Heavy machinery the future is electric

Speaking of hybrids, we tend to think of cars. In fact, most probably we think of the Toyota Prius, which is an excellent hybrid vehicle that has earned its well-deserved reputation. The hybrids have found their niche due to fuel savings they achieve and that is always attached to an equally significant reduction in emissions. Also they get additional savings in terms of lifetime of motor (in a given period of time the combustion engine is less pray on), and for wear of certain components: The braking system substantially prolongs its duration since a good part of this task is performed by the electric braking mechanism also used as energy recovery system. Naturally the question arises: Can we move this large-scale, heavy machinery? Fortunately, many engineers have done before this question with a yes. Although they are unknown to the general public, and there are options in the field of heavy machinery to work vehicles hybrids. Doing a little searching on these issues, we can find some very interesting cases.

We are talking about a truck with a load capacity of between 360 and 400 tons, used in open pit mining. The truck has a diesel engine 90 liter engine, 20 cylinders in V, and 3650 horsepower, designed by the manufacturer MTU. The  same engine is used in some airports to move emergency electric generators. It can produce 2.7 MW

Komatsu series E

Komatsu in 1996 began using electric propulsion systems for mining trucks. It has a number of trucks in this line, from the small family (730E) to the greatest of them (960E with an 18-cylinder diesel engine and 3500 horsepower engine), and all have electric drive systems.

As trucks (with electric drive) from other manufacturers in the mining sector, the truck offers the possibility of using a catenary system to improve performance and significantly reduce operating costs.

The manufacturer seems determined to continue investing in this line and, today, is providing updates and news trying to offer even better performance. In the video using a catenary system is shown in a mining open pit. The figures presented are the most eloquent.

In presenting this bulldozer, although many details were not given, it does indicate some key facts: Its price is 20% higher than the conventional model (Caterpillar D7R). The estimated recovery time from the extra investment is 2.5 years. Fuel savings is obtained between 10 and 30%. With the same amount of fuel, you can move 25% more material than the conventional model.

Hybrid port cranes

The sector of heavy cranes (port cranes, overhead cranes) has also been able to see the advantages of using electrical devices. Some manufacturers already offer such cranes to customers.

Hybrid trains

Finally, other means of transportation that we have become accustomed to see electrified. In this case, the advance is the ability to use without overhead lines, but using a hybrid train (diesel / electric) instead of using traditional diesel locomotive. The Tango 730, which has recently begun to operate using this system. For now, it has been reduced nearly an hour the time spent on the journey of some routes.

In short, it appears that the field of heavy machinery begin to see the advantages of using hybrid mechanisms. In addition to the cases presented, we find hybrid wheel loader high capacity (technologies Hitachi L130, Caterpillar 6120B H FS), and other heavy vehicles known as bulldozers and even tugboats. The excellent results obtained make it increasingly more the number of manufacturers that are committed to these technologies, achieving a fuel savings and emission reduction levels several orders of magnitude higher than what a particular user can achieve when you decide to buy a hybrid or electric vehicle.

Heavy machinery

Infrastructure development, construction of roads, buildings, monuments, have become very expensive these days. Clearly, for all types of construction, a large number of equipment and construction machinery, heavy and light are used. But it is not necessary for each new construction to buy a new machine. In fact it is considered a very wise and practical decision to use  used equipment . In this article you will find some tips you can follow to get a good deal on used construction equipment, whether rural equipment or agricultural machinery .

The purchase of second hand heavy machinery for construction is a smart way to save some money .

Do not just watch the machinery or construction equipment

When you as buyer decide to opt for the purchase or rental of construction used equipment, always try to use it yourself. Even if you are sure that the machine is reliable, the model or brand is a well-known brand, and you know the seller personally or appears to be trustworthy, you should still try the construction equipment itself. Purchase and sale of heavy machinery used is like buying a new car. Undoubtedly, the car may look good, but you cannot buy unless you take a drive test. Similarly for construction equipment or agricultural machinery, try what the team has to either lift, dig, scrape, push, etc.

Before construction machinery rental take your time to assess your condition

Slowly and carefully, and constantly observe the heavy machinery used. Do not take the decision hastily. New paint jobs on the machine make it look good and may even cover many problems. Therefore you must identify if there is any patch of rust or damage covert. Check the bottom of the equipment for leaks. Hoses and valves must also be checked properly before and after the test drive.

Whether rural or agricultural machinery use your senses

Do not let your eyes fool you. Use all your senses. Pay close attention and listen to the engine and hydraulic system at the time you test the equipment or construction machinery. Are you putting more pressure on the machinery or is it doing more sounds than it should? Do you notice burning gas smells? Are there electrical issues? Are the controls and buttons as responsive as it should?

It is very important to buy used special machinery or farm equipment, always concerned with the respectable and reliable distributors. If you buy construction equipment from individuals or businesses not engaged in the sale or rental of heavy machinery, it is likely that you face many setbacks. Buy from reliable sources has many advantages, such as:

  • They have a reputation in the industry.
  • They know that if you go to buy used construction machinery at present, is likely to buy a new machine in the future.
  • They can repair any problems with the equipment.

Heavy equipment

Our main concern when acquiring an asset is to preserve it and in the event of a loss, to be able to replace it. Today we will talk generally about a policy for Heavy Equipment.

This policy provides coverage for damages that may occur to mobile equipment that does not require a license plate and are at times required to move over public roadways.

This equipment includes:

  • Tractors
  • Backhoes
  • Cranes
  • Forklifts
  • Graders
  • Farm Equipment


  • Fire and/or lightning
  • Theft
  • Explosion, except the explosion originated within a steam boiler or internal explosion
  • Cyclone
  • Tornado and/or hurricane
  • Flooding (flooded streets)
  • Earthquake
  • Collapse or sinking of bridges, piers or sewers
  • Collision
  • Mud slides

Overturning or fall of machines operated with gasoline, diesel, fuel, vapor or electricity Derailing or overturning of driving equipment.

As you can see, this policy covers the equipment itself. Therefore you must consider contracting an additional policy covering civil liability in order to cover possible damage to third parties that may be caused by the equipment.

In order to provide you with a quotation for this policy, we need to obtain certain information:

Make, model, series, value, year, engine, weight. If other information is required, the insurance company will so advise.

We recommend that you approach your insurance broker for more details if you require this policy and request several quotations to obtain the best coverage and rates.

Heavy equipment – buying tips

Sometimes it is better to think twice before spending a lot of money in new heavy construction machinery or equipment. You can save a lot of funds by purchasing used equipment. But before reaching a decision you may want to think about it.

Used equipment could be a solution for your business, as long as the machinery works as it should. Of course, it is used, but the machinery used is typically refurbished and has technical reviews. But perhaps your personal experience is better than all those criteria. Although the used machinery looks great, is a famous brand or the seller convinced of the quality of your used equipment, you should be trying it before you buy. Always try to test the used machinery before purchasing or have someone to test the used machinery to you. Scraping, digging, lifting, unloading, pushing, whatever function the vehicle has. Go through all the functions of the used machinery and make sure they all work.

Visual inspection is another form of control for used construction equipment. Even if you have already made a decision on the purchase of equipment and construction, you should be entitled to a good bargain. And good business means you get a good quality used heavy machinery for less. Take the time to inspect the used construction equipment, and try to cover all important areas. Paint Quality of used equipment is not critical. However rust is a problem, so try to see if there are stains or covered only by reason “cosmetic” holes. Grab a tool and try to push or strike at suspicious areas of the used heavy machinery to see if any rust falling on the ground. Slide under the used machinery and search for leaks. Try the potential problem of filtering the used machinery after having passed the driving test. Also check valves and hoses before the test drive, and then see if leaks are present in these places.

The test should not stop here. Listen to the engine for more than a minute or two. Also listen to the hydraulic system when the used heavy machinery is carrying out special functions. Try to detect any strange smells such as burning oil or electrical shorts. When driving or levers, try to feel if the controls work as they should. However, you should keep in mind one thing: even the new heavy equipment may be faulty at times, so be prepared to deal with any problems that may arise with the used machinery, and not just assume the problem was caused by the fact that the machinery was old.

As a final advice of your shopping adventure of used construction equipment, try to avoid buying from people who have no knowledge of construction equipment. Construction equipment distributors can often offer a maintenance service and warranty with your used construction equipment that can extend from 30 to 60 days, making sure that unexpected problems will be treated professionally.

And of course, do not forget to negotiate the price of used construction equipment. You can find a dealer that is flexible with price negotiation and give a better deal than private owner. Good luck shopping for used machinery. For more resources about used heavy equipment or even about used machinery please review

Diagnosing problems in the John Deere system

The first name for all what is related to John Deere tractors. Their distinctive green tractors are tough and reliable. This company manufactures many models as utility tractors, four wheels engines and combines. These are the lines of superior machines. However, as with many heavy farm equipment has many moving parts, cracks inevitably occur in the hydraulic system. There are several steps to diagnose before calling the mechanic John Deere for what can be an expensive visit.


  1. Check the oil level if the system pumps is noisy. Fill as necessary. Replace oil and filter if the oil viscosity is not correct. Check whether the ventilation cover of the reservoir is locked.
  2. Check air leaks in the internal air pump and accessories if there is a system of oil pumping fluid is low. If necessary, replace it. Check if the valve is partially open. If it is, close it.
  3. Check if the levers surround the pivots and if they rise and fall correctly. If necessary, lubricate the link. Check that the cylinder axes are bent. Make sure the cylinder and the hub are not overloaded. Entry checks to see if there is low oil fluid coming from the pump.
  4. Check the axillary hydraulic bucket handles if it’s not leaning back or forward too slow. Check if the handle is blocked in the holding position. Put it in neutral.
  5. Preselecting doesn’t open the valve if the hydraulic oil overheats. The passage of oil to the engine could be closed.

Tips & Warnings

  • If the hydrostatic pressure load is low, the oil level in the reservoir may be low. The load lines may be covered, compared to the same problem.
  • For a noisy pump system pumps cannot be centered neutrally. It may also be that the hand brake is engaged. Check that the suction line is not blocked.
  • If there is no pressure in the hydraulic system, the hydraulic pump can be worn. It may also be that the exhaust valve is damaged. For this problem, see the sales agent of John Deere.
  • For problems with levers that are not properly raised or lowered, this could indicate that the rotary pump is damaged. Consult your sales representative John Deere by this problem.
  • If the hydrostatic head pressure is low, this may indicate a malfunction in the exhaust pressure of the load. The exhaust will need to be replaced by a technician John Deere.

Definition of backhoe

A backhoe is a machine that can do the work of a charger front, a bulldozer and an excavator. This versatile equipment used for heavy digging, gardening, smaller buildings and urban engineering projects. It is similar to a tractor with a front loader mounted on the front and an arm and bucket at the rear. Because it’s sitting on a tractor with a diesel engine, it can lead directly to a job site instead of being loaded onto a trailer and be pulled.


The backhoe was developed in 1953 by Joseph Bamford in the UK, where it is called a “JCB” by the inventor. He added a bucket mounted on the front and a backhoe to an agricultural tractor, creating a very versatile piece of equipment. Backhoes became very popular in the US in 1960.

A versatile piece of equipment

Its precise controls and the relatively small size make useful backhoes in a variety of construction projects, small demolitions, landscaping, building materials moving, excavation, breaking asphalt and paving roads.

Front assembly uses

This machine removes excess dirt from one place or places it in a hole in a process called filling. The front-mounted bucket can tap the loose soil and leveled. Some buckets have a retractable fund called “clamshell” to empty its load more efficiently and is often used for scraping and graduation. The front bowl assembly can be removed to set other tools. A charger can be equipped with a coupler of tools that can expand and retract, allowing different tools to be attached to the unit. A rotor side is a device that allows more joint accessories, making this a suitable machine for carrying tools.

How a backhoe works

A backhoe is digging the earth by pulling back instead of forward lift as a push or a person using a shovel, the operator must be able to handle a backhoe  and the bucket. The backhoe is more complex, requiring skill and experience as the operator must be able to use a control lever while driving the tractor. There are three separate hydraulic connections that must be operated in coordinated steps. The machine arm extends to dig, then pull the bucket back and then push through the soil. This process is repeated until a pit or trench is dug. The hydraulic system can deliver tens of thousands of pounds (kilos) of pressure, much higher than men with shovels, and little time is needed to do a job.

Innovations Backhoe

Kubota has made small and compact tractors, sold with a backhoe configuration for homeowners for projects under excavation. The Dynahoe was originally developed in 1959 by Bucyrus-Erie with a gasoline engine. In 1970, a four-wheel drive system is incorporated in a backhoe loader with diesel engine. You can maneuver in rugged terrain and has been followed by the 590 Turbo Case designed by a twin-turbo setup attached to the engine, increasing power.

Cat backhoes problems

Caterpillar Inc. (Cat), a global vendor of heavy land-based removal equipment of Peoria, Illinois, is well known as the largest manufacturer of construction and mining equipment in the world. One of the machines that it does is the backhoe / loader, commonly used in small ditches work for companies of public services, but that team is not without problems.

Cat history

Caterpillar has been since the last decades of the 1800s, and is known for its excavators (conducted on the tracks), and the largest mining truck, the 797E. Cat has earned a reputation for producing machines seen as the “gold standard” of heavy equipment in the industry.

Backhoe functions

The Cat backhoe works as any other brand. Its main components are a tractor powered by a diesel engine and massive hydraulic systems for front and rear attachments. The front of the machine is a loader bucket-shaped, usually with a capacity of one cubic yard, which is used to move large amounts of land to establish degrees and loading trucks. The backhoe has a digging tool consisting of a main arm, a secondary arm (rocker) and a small toothed hub assembly designed to rip through compacted soil and cement. The end of “hoe” tractor is commonly used for digging by residential utility companies, such as energy, telephone and cable television, and is small compared to most other Cat machines.

Case against CAT backhoe

The Case backhoe is considered by the operators of construction equipment as the fastest backhoe in terms of daily production of trenches and most reliable by the number of hours between breakdowns. In the 1980s, Cat decided to start making their own backhoes. One might assume that a company that can successfully produce one of the largest land moving equipment of the world could be equally adept at making the smallest backhoe; however, this was not the case. The first models had more common problems, including a slow hydraulic and excess gross weight.

Cat backhoes problems

Construction companies expect their backhoes to dig trenches feets per day, and Case backhoe, a fast machine, you can easily meet production standards. The Cat, however, operates at a much slower rate than Case. The speed of the boom for a Cat, the rate at which the operator can rule out a bucket of dirt aside, and after further digging, is slow and has never equaled that of the Case. The backhoe Cat brakes have also been a problem, not because they are inefficient, but because they are always loud and irritating for anyone in a nearby area.

Cost of a cat

Typically, a backhoe Case basic and stripped cost about US $ 45,000, while a similar model Cat cost about US $ 10,000 or US $ 15,000 more, probably because it carries the name Caterpillar (prices as they were in November 2009). Regardless of the problems that has a Cat backhoe when compared with other popular brands, it remains a powerful and reliable reputation worthy of the Cat machine.

Calculating rates of heavy equipment

The rental of machinery includes bulldozers, backhoes, large dump diesel engines, loaders and other large buildings and equipment business. When a rental business operating heavy equipment, rates are determined based on the owner’s desired benefit over two to four years. To determine what types of benefits it provides, the costs of maintaining the equipment must be considered, taking into account the depreciation of the equipment over time. The amount of the value of equipment depreciates over time,  the rate should be calculated in planning as an expense (also called “responsibility”.


  1. Visit the local government office in the county where each piece of heavy equipment has its registration taxes and questions about the acquisition or purchase of a list showing the three years of depreciation of the same make and model that will rent. Since literally thousands of different county governments are around the United States (and the provincial governments of Canada), the depreciation rates are highly dependent on how the local government determines the valuation of such machines.
  2. Visit several auctions of heavy equipment where equipment similar to yours are sold after three to five years of use and record the final selling prices. Between step 1 and this step, you have two numbers value for each machine type: a depreciation schedule of the government and a price based auction after three to five years of use. For the rest of this article, a maximum of 5 years rent will be assumed by way of example.
  3. Sum depreciation government based on the final auction price after five years for each machine and then divides the sum of the two numbers by two. Suppose the machine sold for $ 100,000 in new sales floor. If the depreciation of the government after five years showed a loss in value of $ 40,000 after five years and is selling machine in auctions by an average of $ 70,000 after five years, then we have two numbers: US $ 60,000 value after five years according to the government and the value of $ 70,000 after five years in accordance with the current auction rates. Adding the two together amounts to US $ 130,000 if divided by two giving a final average value of $ 65,000 after five years of use. Subtract the $ 100,000 US $ 35,000 machines is depreciated over five years on average.
  4. Calculate rates for hours of use, so the machine is amortized over five years and the average pay for depreciation using the above figures. In Step 3, the new total cost of the machine was $ 100,000 and the average total depreciation over five years was US $ 35,000. Adjust the start speed per hour so after five years, the machine will generate US $ 135,000. Thus, the responsibility of depreciation became income. When the machine is sold after five years, the final sale prices will also income, because the responsibility of depreciation has refused.
  5. Determine the total cost of employees and expenses of the business operations and then this final figure includes costs for business. These expenses should be planned to “go to the customer” if the depreciation-denial strategy described in this guide is used, as this will prevent your rental prices to be competitive. Instead, use the receipts for purchases and maintenance, tax deductions at the end of each year to reduce the amount of taxes you must pay.
  6. Establishe a preliminary rental price based on the machine you have to pay for your new price in five years, plus the impairment loss. In this example, $ 135,000 is the desired amount of more than five years, and then adds an income of 60 percent extra on top of this to have a cash flow to purchase parts for the repair and the payment of wages the employees. In this example, there is an additional US $ 81,000. For five years, the total to be collected at this point is US $ 216,000, which is US $ 116,000 more than the cost of a new machine at the dealership at the time of purchase. This percentage should be changed based on the number of employees and what the agreed salary per year.
  7. Set personal cost of living wages for a period of five years for you and your family and add them to the figure of five years of US $ 216,000. This is where rental prices must be balanced to be competitive with what other rental companies are renting heavy equipment for its units. In a way, this will determine how you’re going to live in this kind of business. A good percentage of the cost of living, however, it should be about 20 percent of total annual five done before. Thus, 20 percent of US $ 216,000 is US $ 43,200 of annual income. In five years, an additional US $ 216,000 is added for a total of $ 432,000 over five years.
  8. Setting the hourly rental brings the final amount in five years. A good estimate is to keep the machine rented 200 hours per week, or 800 hours per month, allowing weekends are excluded. For five years, this will be around 48,000 hours. If the machine is rented for US $ 10.00 per hour to the hours leased, if successful, will generate US $ 480,000 during the period of five years. Adjust to US $ 20.00 per hour if the machines just try to rent half of the required hours.

Tips & Warnings

  • The estimates here are very conservative and somewhat rigid. A rental company of heavy equipment may have a greater number of employees or fewer employees. In addition, maintenance costs can vary in different areas and these differences have to be considered in a way that the business still generates the desired level of revenue. In the real world, to pay all costs while still making the desired benefit may require an hourly rate of rent between US $ 50.00 and US $ 100.00 per hour in some cases. Serve your business interests to establish your closing prices (as long as competitive) to what others are renting similar machines in a given area.
  • This article and the final breakdown of the rental cost per hour is a conservative business that makes a living renting more than one machine at a time instead of one. However, this breakdown for example must scale to your desires, regardless of the number of machines in the fleet.
  • Know your costs of doing business and discover all the big and little things in your final hours chosen. Add to insurance costs of the machine, office equipment and computers, fuel costs, insurance workers’ compensation for the employee (s), taxes in accordance with state and federal codes for your desired income taxes, etc. Every business is unique and all things must be taken into account. Consider hiring an accountant to help you make your business profitable.
  • The annual gain is, in its most basic form, the operator desired gain added on top of total costs, liabilities and taxes.

Preparation Guide for Heavy Equipment Mechanic exam

For an individual seeking a career as a mechanic of heavy equipment, there are several types of preparation guides for exam. The preparation guides can be bought or borrowed from your local library. The preparation guides are comprehensive and extensive, and prepare the individual to become a mechanic of heavy equipment. These guides are formatted with a strategy that includes information on topics, creating work space scenes and environment; at the end of each section, pre-tests are provided.

Mechanical knowledge

Basics of machinery and mechanisms are the foundation of exam preparation guides. The guidelines incorporate a strategy based on theory and illustrations of machinery and knowledge working on computer. The strategy extends the basic knowledge of various mechanical processes –electric generated steam, hydraulics– and how to use these processes in a mechanical environment. A recommendation to understand the mechanics portion of the study guide is attached using a basic guide and become familiar with electrical and hydraulic terms.

Logic and reasoning

The exam preparation guides include sections of mathematical logic and reasoning strategies to test the thinking process. The guidelines are designed to improve research skills and solving problems using individual deductive strategy; reasoning prepares an individual to think on a larger scale when confront with a mechanical problem involving a piece of machinery or security situations. In combination with the preparation guide for the exam, the basic study of mathematical disciplines such as algebra, geometry and trigonometry can improve knowledge of logic and reasoning for examination purposes.


Understanding security is mandatory for an individual seeking designation as a mechanic for heavy equipment. The preparation guide provides a strategy for implementing safety awareness in industrial environments and situations. The security portion of the guide tests the individual’s ability to detect dangerous situations through critical thinking and evaluation of a work environment. In conjunction with the study guide, an individual should also consider taking a course or seminar on ISO 9000 safety requirements that will be in the actual exam.

Equipment Identity

Heavy equipment mechanics should know when to use appropriate analytical tools to detect and repair a problem. The guide provides preparation test scenarios and strategies for using voltmeter: hydraulic equipment pressure test and general electrical problems. A strategy plan to determine the various types of equipment and become familiar with them, is to buy a guide of heavy mechanical electrical and hydraulic equipment which details the history and evolution of heavy machinery equipment in various industrial environments.

Apprentice training

Individuals who plan to be mechanics of heavy equipment must have two years of training as an apprentice under a certified mechanic. Apprentice training, combined with study preparation guide, is a strategy that pays big dividends. Working scenarios can familiarize the individual with mechanical concepts and terms before the test for certification.
