Selection of construction equipment

A successful proposal involves the management to be given to construction crews.

As with all activities in a bid to find the costs of resources such as team building, help is essential background information. Therefore, the first thing to do is visit the “Tender Information Centre” (CIL) of the entity. There will be something very precious: the names and specific data on the “Dealers”, the distribution companies of construction equipment. Then, you need to go to work packages developed by each of the members of the team, which form the basis for scheduling the tasks of the proposal. Each estimator should have clearly defined the activities of their respective expertise, and resources that each requires for its proper implementation, including construction crews.

But nevertheless, in the specific case of the earthmoving work, present in varying degrees in all the work of engineering, it is important to know the size and nature of the terrain to adapt. With this information you can know fairly accurately what the performance of each team and, incidentally, the utilization time of these, such as bulldozers, tractors, motor graders and more. Next, the box of equipment, including, if applicable, trucks and scrapers for horizontal transport and vertical transport cranes should be developed. And of course, the amounts of each. The next step is to send the information to the “Dealers” in order for them to prepare their proposal.

So far there is nothing new, it is standard procedure that applies in such cases. But now, it is something interesting that can define a tender. There are three possible alternatives when it comes to using construction equipment bound for a work: that is owned, leased, or leasing. Its correct selection may be the factor that allows you to top the bid. It is so expensive in this type of projects, any decision either way can mean large amounts will definitely make the difference between the two proposed lines.

In appearance, it may be best to use the equipment owned by the company and quote this line prices low or zero times. Obviously, this approach can lead to a low price with high chances of winning the bid, but contains several drawbacks. One is that profits will be lower because the cost of operating the equipment will have to cover the contractor. Additionally, you may run liquidity, resources are reduced, the displacement is expensive and you have to cover the amounts for warehousing, maintenance and repair. This, regardless of the implicit cost of obsolescence. But, also, there are positive aspects, complete control of the equipment, tax-deductible costs and high familiarity. Moreover, studies suggest using this possibility when the use of the equipment is above 70% of the activities time.

Now, in the case of use of rental equipment they have advantages of flexibility, pay only for actual use, no involvement by way of travel, use of new models and low financial effort. But, also, it is more expensive and may affect the budget. It has been found that for contracts of more than three months can be costly. Also, you should consider whether it is hired for days, weeks or months.

Finally, there is the widely used figure of leasing. It is more expensive when compared with purchased equipment and hired who must answer for the damage or loss. You pay monthly although the team does not work, interest rates are higher and the penalty for breaking the contract is high. But it is a good choice when funds are limited and the team works less than 60% of the time. In addition, obsolescence is avoided, no advance payments and new models can be selected.

We can see well, although in a very general way, that the selection of construction equipment bound budget for a tender, contains a number of subtleties that cannot be ignored and, instead, deserve a serious, deep and careful study.


Heavy machinery can help with a wide range of tasks, from soft drinks bottling plant to build a new school. But the machinery is powerful and relentless and presents a safety hazard when used incorrectly or haphazard way. Equipment of all types is useful, and workers can operate safely by following some simple rules for a wide variety of equipment.

Read the owner’s manual and only use a machine if you have the right qualifications.

Wear eye protection at all times. Use dust masks when necessary to protect your lungs from foreign debris. Use ear protection when noisy machinery to prevent hearing loss. Wear a helmet when there is a potential for falling objects.

Tie you hair or put it under a tight hat. Avoid using anything that is loose, which could get caught in the machine.

Make sure there is a stop button easily accessible in case an emergency occurs.

Keep well-oiled and maintained so that it is in proper operating condition and less likely to experience a failure, which could create a dangerous situation machine.

Surrounding area with good lighting so you can see the machine and its surroundings clearly.

Keep the space around the machine free of objects and other workers. Make sure that no power cables or other cables running across the floor in a way that might cause someone to trip. Clean up spills immediately.

Do not leave the machine unattended. Turn the machine off when not in use, and inspect it carefully before using it again.

Role of heavy machinery

With the introduction of heavy machinery in the world of construction, primarily to move large loads and replace the man in jobs requiring more physical effort and an increased risk in the execution, they were transformed into simple relative to earthworks and other materials associated with large public works.


It works like the human arm – you can dig, lift the material and unloading. A skilled operator knows backhoe operations require more the use the front loader. The operator must move the backhoe vehicle and operate simultaneously. The beginning of the operation to dig the hole and then download the material dug on the side (or even loading a truck parked nearby).


The caterpillar is perhaps the most basic and versatile machine in the construction industry. It serves many purposes, such as moving loads pushing or pulling them. These are versatile machines in many construction projects, where they can be used from the beginning to the end. Regular earthmoving operation is practically a set of straight forward and backward movements. When the tractor moves forward, the front blade cutting engages the ground, for its load.


It is often used for excavation of rock and soil, however, thanks to its many accessories can also be used for cutting steel, breaking concrete, and holes in the ground, before the foundation of gravel pavement. You can dig, lift the material and unload.


It is a very specialized hydraulic machine that facilitates the work of accelerated compaction and landfills.

Road construction has both science and art. However, forest, both in its planning and execution require a high degree of peculiar qualities. A varied knowledge, extensive experience and constant monitoring are essential for facing difficulties arising from the distance, isolation or limited material means. However, a job is essential because it can be said that where there are no forest roads there is no forest exploitation.

Rubia, a range of TOTAL lubricants approved by manufacturers, is one of the most complete ones. The products are suitable for all makes of trucks, buses and passenger vehicles; TOTAL will work with you to identify the specific products that meet your needs and keep your fleet rolling.

Maintenance of heavy machinery

Operating heavy machinery is very expensive. Do not make repairs to that type of equipment due to poor policy maintenance is simply bad business. Sticking to a list of maintenance can take as little as 15 minutes a day and you can easily find a problem before working days lost due to repairs to equipment. Poor maintenance on heavy equipment can endanger your employees.

Daily maintenance

Make a program to maintain equipment and stick to it. There are certain tasks to do daily, while other tasks need to be completed in a longer program. Once you decide something in a program, prepare a list of maintenance. Daily walks around each team in operation. While doing a visual inspection, check the used and signs of leakage of oil or antifreeze liquid. Make sure the tires are inflated to the proper pressure. Take time to remove debris from the machine. Tap bands and chains to make sure they are not too loose. Lubricate couplings that require daily greasing. Make sure emergency signals and safety equipment are in place. Check the fluid levels in oils, antifreeze and hydraulic. Fill them when necessary. When not at the appropriate levels the life of your heavy equipment is shortened. Check the air filter and clean it if necessary.

Quarterly maintenance

When your machine has 500 operating hours, or about 3 months of service, you should perform maintenance deeper. Change the engine oil, oil filters both the engine and the hydraulic system filter. Replace diesel fuel filter also as part of the quarterly maintenance.

Maintaining season finale

At the end of the season, or at least once a year, change the transmission fluid and the hydraulic oil. Check the antifreeze in your radiator to make sure it is in good condition for the winter season. Check hoses and belts. Drain the fuel from the last season of the tank and fill with a mixture of fuels (can be biodiesel and diesel with ethanol) or type “artic” (a brand that prevents paraffin crystals to deposit on the bottom) so that fuel line does not crystallize when you turn on in cold weather. Thoroughly wash the vehicle. Pay special attention to cleaning the engine and chassis. Clean the cabin and air filters. Make sure the air conditioning unit is clean. Make sure all lights work and replaces defective. Inspect the tires for signs of wear and tear. Replace worn tires during the off season so as not to lose valuable work time.

Definition of backhoe

A backhoe is a machine that can do the work of a charger, a bulldozer and an excavator. This versatile equipment it’s used for heavy digging, gardening, smaller buildings and urban engineering projects. It’s similar to a tractor with a front loader mounted and an arm and bucket at the rear. Because it’s based 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 was called “JCB” by the inventor. The inventor added a bucket 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 it useful in a variety of construction projects, small demolitions, landscaping, building materials moving, excavation, breaking asphalt and paving roads.

Front assembly use

This machine removes excess dirt from one place or places in a process called filling. The front-mounted bucket can tap the loose soil and level. 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 couple 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.

As a backhoe works

A backhoe dig earth pulling back instead of forward lift as push or as a person using a shovel; the operator must be able to handle a backhoe bucket and the bucket itself. 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 in little time.

Backhoe Innovations

Kubota has made small and compact tractors, sold with a backhoe configuration for homeowners. Dynahoe was originally developed in 1959 by Bucyrus-Erie with a gasoline engine. In 1970, a four-wheel drive system was incorporated in a backhoe loader with diesel engine. It was able to be maneuvered in rugged terrain and has been followed by the 590 Turbo CASE designed by a twin-turbo setup attached to the engine, increasing power. The finger is a newer spoon with a hinged metal rod, which is used as a thumb to pick things up.

Diagnosing problems in the John Deere systems

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 wheel engines and combines. These are the lines of superior machines. However, as with many heavy farm equipment has many moving parts and cracks inevitably occur in the hydraulic system. There are several steps to diagnose before calling the mechanic from John Deere which can be an expensive visit.

Instructions :

  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 pumping fluid check oil level. If necessary, replace it. Check if the valve is partially open and close it.
  3. Check if the levers surround the pivots rise and fall correctly. If necessary, lubricate the link. Check the cylinder axes if is bent. Make sure the cylinder and the hub are not overloaded. Entry checks to see if there is fluid low coming from the pump.
  4. Check the auxiliary hydraulic bucket handles if not lean back or forward or too slow. Check if the handle is blocked in the holding position and put it in neutral.
  5. Preselecting opens 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. 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 the exhaust valve which 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 of John Deere.
  • 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 John Deere technician.
