TRUCK:Heavy equipment refers to heavy-duty vehicles, specially designed for executing construction tasks, most frequently ones involving earthwork operations. They are also known as heavy machines, heavy trucks, construction equipment, engineering equipment, heavy vehicles, or heavy hydraulics.

Mobile Crane:

A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers. They are designed to easily transport to a site and use with different types of load and cargo with little or no setup or assembly. Mobile cranes generally operate a boom from the end of which a hook is suspended by wire rope and sheaves.

Excavator:

Excavators are also called diggers. These are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the “house” .The house sits atop an undercarriage with  tracks or wheels. A cable-operated excavator uses

winches and steel ropes to accomplish the movements. Modern, hydraulic excavators come in a wide variety of sizes. The smaller ones are called mini or compact excavators.

Usage:

Digging of  trenches, holes,  foundations

Material handling

Brush cutting with hydraulic attachments

Forestry work

Forestry mulching

Demolition

Crawler dozer:A bulldozer is a crawler continuous tracked tractor equipped with a substantial metal plate known as a blade used to push large quantities of soil, sand, rubble, or other such material during construction or conversion work and typically equipped at the rear with a claw-like device (known as a ripper) to loosen densely compacted materials. Bulldozers can be found on a wide range of

sites, mines and quarries, military bases, heavy industry factories, engineering projects and farms.The term "bulldozer" refers only to a tractor usually tracked fitted with a dozer blade. Most often bulldozers are large and powerful tracked heavy equipment.

Loader:

A loader is a heavy equipment machine often used in construction, primarily used to Load material (such as asphalt, demolition debris, dirt, snow, feed, gravel, logs, raw minerals and recycled material . A loader is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted square wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground.

Skid steer loader :A skid loader or skid-steer loader is a small rigid frame, engine-powered machine with lift arms used to attach a wide variety of labor-saving tools or attachments.Though sometimes they are equipped with tracks, skid-steer loaders are typically four-wheel vehicles with the wheels mechanically locked in synchronization on each side, and the left-side drive wheels can be driven independently of the right-side drive wheels

Graders:A grader, also commonly referred to as a road grader, a blade, a maintainer, or a motor grader, is a construction machine with a long blade used to create a flat surface. Graders are commonly used in the construction and maintenance of dirt roads and gravel roads.

In the construction of paved roads they are used to prepare the base course to create a wide flat surface for the asphalt to be placed on. Graders are also used to set native soil foundation pads to finish grade prior to the construction of large buildings.

Tower crane:Tower cranes are a common fixture at any major construction site. They often rise hundreds of feet into the air, and can reach out just as far. The construction crew uses the tower crane to lift steel, concrete, large tools like acetylene torches and generators, and a wide variety of other building materials. Tower cranes are a modern form of balance crane that consist of the same basic parts. Fixed to the ground on a concrete

slab and sometimes attached to the sides of structures), tower cranes often give the best combination of height and lifting capacity and are used in the construction of tall

buildings.

Truck mounted crane:A crane mounted on a truck carrier provides the mobility for this type of crane. This crane has two parts: the carrier, often referred to as the Lower, and the lifting component which includes the boom, referred to as the Upper. These are mated together through a turntable, allowing the upper to swing from side to side. These modern hydraulic truck cranes are usually single-engine machines, with the same engine powering the undercarriage and the crane. The upper is usually powered via hydraulics run through the turntable from the pump mounted on the lower.

Dump truck:

Dump trucks or production trucks are those that are used for transporting loose material such as sand, dirt, and gravel for construction. The typical dump truck is equipped with a hydraulically operated open box bed hinged at the rear, with the front being able to be lifted up to allow the contents to fall out on the ground at the site of delivery. Dump trucks come in many different configurations with each one specified to accomplish a specific task in the construction chain.

Crawler excavator:

A crawler excavator (crawling digger) is a vehicle designed to dig or move large objects, and is classified by its mode of locomotion. The many types of excavators include wheeled, walker, towed and rail excavators. More like a Sibling to the crawling-tanks widely used by the armies, these crawlers move upon the same rotating wheel systems; but along with that have the ability to Dig, Pick and Transport Earth-substance On the Go.

Road Roller:

A road roller sometimes called a roller-compactor, or just roller is a compactor type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations, similar rollers are used also at landfills or in agriculture.In some parts of the world, road rollers are still known colloquially as steam rollers, regardless of their method of propulsion. This typically only applies to the largest examples (used for road-making). Road rollers use the weight of the vehicle to compress the surface being rolled or use mechanical advantage (vibrating).

Conveyors:

A conveyor system is a common piece of mechanical handling equipment that moves materials from one location to another. Conveyors are especially useful in applications involving the transportation of heavy or bulky materials. Conveyor systems allow quick and efficient transportation for a wide variety of materials, which make them very popular in the material handling and packaging industries.

Sheer foot roller:

A cylindrical steel drum to which knob headed spikes are fastened used for compacting earth also known as tamping roller. A self-propelled or towed drum like roller with projecting studs that penetrate the surface of the ground used to obtain deep compaction of fill material Effective for compaction of clay soils.

Concrete mixtures:

A concrete mixer (also commonly called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete. A typical concrete mixer uses a revolving drum to mix the components

Concrete truck:

Special concrete transport trucks (in–transit mixers) are made to transport and mix concrete up to the construction site. They can be charged with dry materials and water, with the mixing occurring during transport. With this process, the material has already been mixing. The concrete mixing transport truck maintains the material's liquid state through agitation, or turning of the drum, until delivery.

Stone crusher:

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Paver:

A paver (paver finisher, asphalt finisher, paving machine) is a piece of construction equipment used to lay asphalt on roads, bridges, parking lots and other such places. It lays the asphalt flat and provides minor compaction before it is compacted by a roller. The asphalt is added from a dump truck or a material transfer unit into the paver's hopper. The conveyor then carries the asphalt from the hopper to the auger. The auger places a stockpile of material in front of the screed. The screed takes the stockpile of material and spreads it over the width of the road and provides initial compaction.
