It was a time when the construction of palaces or castles took away decades. Today, your services available: truck, auto cranes, bulldozers, concrete mixers, buwith revealing installation, crushers, excavators, timber, pipe layers, dump trucks and other construction equipment. In addition to construction, such a technique also used in mining, forestry and agriculture. Construction equipment as you can buy and rent on the desired period of time. For those who do notmoney ad advise see section on National trading floor "from hand to hand".

Special equipment can be divided into such types: road construction, rigs, excavators, forestry, loaders, dump trucks, construction cranes. In this article we consider the basic and most-usedcular species: bulldozer, excavator, loader, crane and truck.

loader

It is a bright representative of the industrial machinery used for loading, lifting, loading and transportation of materials and goods. What, then, are different cranes and loaders? They differschayutsya that propelled trucks are much more compact and agile than the cranes, which is why they are indispensable in engineering, manufacturing, commerce, warehouses and agriculture.

Construction crane

This is a lifting appliance that is needed for moving and lifting during repair, installation and handling operations.

The crane consists of a 3-hourchildren:

  • The base (skeleton, skeleton) of the crane, which is a metal structure, which includes flights, support and arrows;
  • The lifting mechanism that Commission, and include a lifting body (steel wire rope and chain), cargo winch, Front-end opgan (hook and loop);
  • Lifting equipment that is as non-automatic (hook or loop) and automatic operation (electromagnet spreader or pneumatic suction cup).

Classification construction cranes:

  • According to the type of support: support, Pneumatic, suspended, tractor, rail and others.;
  • By type of lifting body: grab, hook, tick, container, magnetic crane;
  • According to the degree of rotation: turning and immovable;
  • According to thePOSSIBILITY move: mobile, resettable, radial, and jack-stationary;
  • According to the type of drive: electric, hydraulic, pneumatic or manual drive.
