Definition heavy equipment

Bulldozer, front push tractor.

Self-propelled machine on wheels or chains, designed to exert a push or pull. The standard does not elaborate on the attachments (blade, ripper, winches, etc.) or its functions or types of work.

Forklift (Forklift)

Moving machines independently on the ground, primarily intended to carry, push, pull or lift loads. To fulfill this function a fit between work rig forklift (attachment) and the type of load is required.

They are suitable for carrying loads of overhang. It sits on two axes: driving, the front and guideline rear. They can be electric or internal combustion engine.


Self-propelled machine on wheels or chains, equipped with a front bucket, support structure and a set of articulated arms, capable of loading and digging  by its movement and the movement of the arms, and raising, transporting and unloading materials.

BACKHOE (loader, mixed, backhoe, and bow tie)

Self-propelled frame on wheels with a specially designed riding both a front loader and a rear hole so they can be used alternatively.

When used as excavator, the machine normally digs below ground level with bucket motion towards the machine, and lifts, collects, transports and discharges material while the machine is stationary.

When used as loader, loading or digging by shifting and movement of the arms and lifts, transports and discharges material.

SKID (Skid)

Self-propelled wheeled machine, equipped with a front bucket, supporting rigid chassis structure, and a steering system using levers or pedals that can stop or control the two wheels on each side. It is also susceptible to assemble numerous tools for special jobs.

Excavators (Backhoe)

Self-propelled machine on wheels or with a superstructure capable of rotating 360 or digging load rises, turns and discharges material by the action of a spoon attached to a set of boom and dipper arm or without the chassis or the supporting structure move.


Self-propelled machine on wheels or chains, metal or rubber, with a superstructure capable of rotating 360 or digging load rises, turns and discharges material by the action of a bucket mounted on a boom and arm assembly, without the supporting structure it moves and with a weight not exceeding 6,000 kg.


Propelled wheeled machine that has an open box with cutting edge between the front and rear axles, which starts, charge transporting material and extends, using the forward motion thereof.


Self-propelled wheeled machine with an adjustable blade, positioned between front and rear axles which cuts, moves and spreads material usually leveling purposes.


Self-propelled or towed machine on wheels, made of one or more cylinders or masses designed to increase the density of the materials: static weight, shock, vibration or Kneading (dynamic pressure) or combination of any of them.

Checklist preventive maintenance for heavy equipment

The devices are expensive and heavy to develop a program of preventive maintenance to last as much as possible. The maintenance department of this type of equipment must carry a checklist of preventive maintenance on every one of the teams to meet the standards of the Occupational Safety and Health Administration (OSHA). This checklist must have data scheduled, the dates that will carry out and documented to meet the federal guidelines.

Date, time and inspector

Each checklist of preventive maintenance of heavy equipment must record the date on which the inspection was conducted, the time it took place and the name of the inspector who completed the checklist. The intention is not only to keep records, but also to allow the maintenance mechanic or the person who carried out the repair to answer questions later from the inspector about the bugs found during the inspection checklist.

Sections of the checklist

Most checklists of preventative maintenance for heavy equipment are broken down into sections, and each lists the parts to be inspected. One of these lists has sections such as what should be inspected from the ground, which parts should be reviewed in the engine compartment and which must be inspected in the cabin. Many of these lists include a section on safety equipment, where the inspector can record the safety equipment such as fire extinguishers, lights and sound warning, security lights and turn signals and devices protection in general, cages and scrollbars.

Breakdown section

Each section of a checklist of preventive maintenance of heavy equipment is broken down into categories. One will be a list of parts or test items. Another category will list what to look for when that element or part is inspected, and the last category should leave space for additional comments or problems encountered during the inspection.
