- Aug 09, 2017 -

Lifting machinery according to its function and structural characteristics, can be divided into the following categories:


1, light and small lifting equipment Light and small lifting equipment is characterized by light, compact structure, simple action, the scope of projection to point, line-based. Light and small lifting equipment, generally only one lifting mechanism, it can only make a single heavy lifting movements. Belong to this category are: jack, pulley, hand (gas, electricity) hoist, winch and so on. Electric hoist is often equipped with running trolley and metal frame to expand the scope of operations.


2, boom-type crane boom crane features can be hung on the hook or other objects on the device in the space to achieve vertical lift or horizontal movement. The boom crane includes a hoisting mechanism, a luffing mechanism, and a rotating mechanism. Rely on these institutions with the action, can make heavy objects in a certain cylindrical space lifting and handling. The boom crane is mounted on a vehicle or other form of transport (moving) tool, thus forming a jib rotary crane. Such as truck cranes, tire cranes, tower cranes, portal cranes, floating cranes, railway cranes and so on.


3, bridge crane bridge crane characteristics and basically the same arm. Bridge cranes include: hoisting mechanism, large, car operating mechanism. Rely on these institutions with the action, can make heavy objects in a certain cubic space lifting and handling. Bridge cranes, gantry cranes, loading and unloading bridges, metallurgical bridge cranes, cable cranes and so on are such.


4, the lift is characterized by lifting or lifting device can only lift along the rail. Although there is only one lift in the lift, but in the lift, there are many other ancillary devices, so separate constitute a class, which includes: elevators, freight elevators, shippers and so on. In addition, the crane has a variety of classification methods. For example, cranes, grab cranes, grab cranes, cranes, metallurgical cranes, stacking cranes, container cranes and rescue cranes, etc., are sorted by transport, fixed cranes, running cranes Truck cranes, crane cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes, cranes , Storage cranes, construction cranes, engineering cranes, port cranes, shipyard cranes, crest cranes, cranes on board.
