Construction Equipment

Standard-sized excavators weigh between seven and 45 metric tons. These versatile excavators are the most common size for commercial construction projects, and offer enough power and hauling capacity to handle a variety of tough jobs.

A wheel excavator is a large heavy equipment machine used in surface mining. The primary function of is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns.

The long boom excavator is a development of the excavator with an especially long boom arm, which is primarily used for demolition and many other applications. Instead of excavating ditches, the high reach excavator is designed to reach the upper stories of buildings that are being demolished and pull down the structure in a controlled fashion.

A Mini excavator is a tracked or wheeled vehicle with an approximate operating weight from 3.8 to 8.7 tones. The Bucket Capacity Range is 0.06 m³ - 0.4 m³. It generally includes a standard backfill blade and features independent boom swing.

A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car). Back then it was based on a tractor and had a rear wheel drive. They are often seen building or removing road blocks and building bases.

An amphibious excavator is a type of excavator that can perform dredging while afloat on soft terrain such as swamp, wet land, and shallow water. An amphibious excavator is better adapted for removing silty clay, clearing silted trenches, swampland operation and shallow water operation than traditional barge-mounted dredgers.

A dozer is a crawler equipped with a substantial metal plate 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 to loosen densely compacted materials. Dozers can be found on a wide range of sites, mines and quarries, military bases, heavy industry factories, engineering projects, and farms.

A grader, also commonly referred to as a road grader, motor grader, or simply a blade, is a form of heavy equipment with a long blade used to create a flat surface during grading. Although the earliest models were towed behind horses, and later tractors, most modern graders are self-propelled and thus technically "motor graders". Typical graders have three axles, with the steering wheels in front, followed by the grading blade, then a cab and engine atop tandem rear axles. Some graders also have front wheel drive for improved performance. Some graders have optional rear attachments, such as a ripper, scarified, or compactor. A blade forward of the front axle may also be added. For snowplowing and some dirt grading operations, a main blade extension can also be mounted.

A road 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. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion.

Soil compaction is a vital part of the construction process. It is used for support of structural entities such as building foundations, roadways, walkways, and earth retaining structures to name a few. For a given soil type certain properties may deem it more or less desirable to perform adequately for a particular circumstance. In general, the preselected soil should have adequate strength, be relatively incompressible so that future settlement is not significant, be stable against volume change as water content or other factors vary, be durable and safe against deterioration, and possess proper permeability.

Tandem rollers are used primarily to compact paving materials, such as asphalt mixes and roller-compacted concrete. These machines have two steel drums that vibrate via an internal, eccentric mechanism, which often can be adjusted to vary the frequency and amplitude of the vibratory action.

The pneumatic tire roller is a self-propelled compaction device that uses pneumatic tires to compact the underlying HMA.

Walk-behind rollers or trench rollers are perfect compactors for narrow work areas that need preparation, such as pavement, shoulders and sidewalks. When equipped with a smooth drum, these rollers compact granular soil such as gravel or sand.
