Introduction

Heavy machinery, known by the other terms: Engineering/construction equipment, earth movers, heavy equipment or just plain equipment, are machines,vehicle machines, in the most basic form, are compound machines composed of simple machines. These components make up the five equipment systems: implement, traction, structure, power train, control and information. Through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied. Currently most equipment use hydraulics as a primary source of transferring power. The use of heavy equipment has a long history. Vitruvius a 1st century B.C. engineer gives detailed descriptions of Roman heavy equipment and Roman cranes in his treatise De Architectura.
Heavy equipment requires specialized tires for various construction applications. While many types of equipment have continuous tracks applicable to more severe service requirements, tires are used where greater speed or mobility is required. An understanding of what equipment will be used for during the life of the tires is required for proper selection. Tire selection can have a significant impact on production and unit cost. There are three types of off-the-road tires, transport for earthmoving machines, work for slow moving earth moving machines, and load and carry for transporting as well as digging. Off-highway tires have six categories of service C compactor, E earthmover, G grader, L loader, LS log-skidder and ML mining and logging. Within these service categories are various tread types designed for use on hard-packed surface, soft surface and rock. Tires are a large expense on any construction project, careful consideration should be given to prevent excessive wear or damage.

Wheel Excavator


The Caterpillar 300 family excavators provide governmental agencies with more working advantages, whether you need more digging depth, more power, greater reach, more lift capacity, higher breakout force or more swing torque. The Caterpillar 300 Family Excavators are recognized by their sleek, modern styling and feature innovative hydraulic systems that put power where and when it's needed most.Increased lifting capacity, improved cycle times and ease of operation lead to increased productivity and lower operating costs.

Telehandler



Move massive amounts of material fast with a
NEW LM5000 Series telehandler. A combination of
outstanding operator efficiency and raw power and
lifting performance makes these new machines the
most effective way to load, stack, scoop and dig.

Larger, more comfortable cab
The spacious modern cab makes you more
comfortable, and more productive. The cab itself is
rounded with expansive visibility to the work area
around you.
Increased lift capacity
Lift capacity up to 8,800 pounds and a lift height
up to 31.5 feet allows you to do things that skid
steers, tractors, wheel loaders and fork lifts can’t,
like stack large balers six to eight levels high, scoop
a bucket of silage from the top of a bunker silo, and
much, much more.Improved reliability,Designed and manufactured by New Holland.

Pipelayers



Cat Pipelayers have been the standard of the pipelining industry for decades. A worldwide network of Caterpillar dealers, in tune with the special high production needs of pipeliners, supports these durable, dependable machines.
Engineered for demanding work. The 572R Series 2 power and versatility, combined with rugged components, are designed for tough and varied working conditions. This machine offers you the reliability and durability you expect from Cat Pipelayers

Cold Planer


A cold planer (also known as a pavement planer, pavement recycler, milling machine or rotomill) is an engineering vehicle used to remove bituminous or asphalt concrete from roadways, resulting in a smooth, even surface. This is accomplished by bringing a spinning mandrel or "head" into contact with the pavement at an exact depth or slope. It is normally fed by conveyor into a dump truck, but can be left in place or "wind-rowed" to be removed at a later date.The new PM-102 combines enhanced production capabilities, optimized performance and simplified service to complete tough milling applications with productive results. The Caterpillar 3126B ATAAC engine is dependable and field proven meeting U.S. EPA Tier 2 and European EU Stage II compliancy. Designed for high production and long life, the PM-102 rotor has quick release conical tool holders for quick and easy tool replacement. And the conveyor can be folded to reduce machine dimensions during transport.

Front shovel


Developed specifically for high production mining applications, the 385C Front Shovel delivers high bucket fill factors and fast cycle times to maximize your productivity. Designed and built to meet the performance and reliability expectations of Cat customers, this machine delivers dependability.The integrated engine oil and filter system extends service intervals. This combines the oil stabilizing systems, Reserve and Centinel, with the Eliminator self cleaning oil filter to extend, with oil analysis, the oil change interval to 4000 hours. Make and model 2 x Komatsu SDA16V160 Type 4-cycle, water-cooled, direct injection Aspiration Turbocharged and aftercooled Number of cylinders 16 Rated power @ 1800 rpm (SAE 1995/J1349) 2 x 2,010 HP 2 x 1500 kW Governor All-speed, electronic.

Bulldozer


A bulldozer is a crawler (caterpillar tracked tractor), equipped with a substantial metal plate (known as a blade), used to push large quantities of soil, sand, rubble, etc, during construction work. The term "bulldozer" is often used to mean any heavy engineering vehicle (frequently loaders and in particular track loaders), but precisely, the term refers only to a tractor (usually tracked) fitted with a dozer blade. That is the meaning used here.Sometimes a bulldozer is used to push another piece of earthmoving equipment known as a "scraper". The towed Fresno Scraper, invented in 1883 by James Porteous, was the first design to enable this to be done economically, removing the soil from the cut and depositing it elsewhere on shallow ground (fill). Many dozer blades have a reinforced center section with this purpose in mind, and are called "bull blades."
