Heavy Construction Machines
Construction equipment range from the very heavy equipment to the portable and mobile lighter equipment, some of them with a precise description of their functions are detailed below.
Engineering equipment with a front bucket/shovel and a small backhoe in the rear combined with a tractor is known as backhoe loader. It is mostly used in small construction sites and in urban engineering such as fixing city roads.
A crawler, which is very powerful and attached with a blade, is called a bulldozer. Even though any heavy engineering vehicle is known as bulldozer, it is actually a tractor with a dozer blade.
Combat engineering vehicles are used for engineering work in the battlefield and for transporting sappers. They are mostly armoured vehicles.
A compact excavator is a wheeled or tracked vehicle with a backfill blade and swing boom. It is also known as mini excavator. The functions and movements of the machines are carried out by transferring hydraulic fluid. This makes a compact hydraulic excavator different from other construction equipment.
To compact gravel, dirt, asphalt and concrete in construction work and road laying a road roller which is also known as roller-compactor would be used.
A motorized cultivator with a rotating blade to work in the soil is known as rotary tiller. They are either drawn behind a tractor or self-propelled.
A crane is a derrick or tower equipped with pulleys and cables for lowering and lifting materials. The cranes used in construction industry are mostly temporary structures.
