Boom crane such as fixed slewing crane, tower crane, truck crane, tire crane, crawler crane, etc. Cable cranes, such as lifts.
According to the nature of lifting: mobile crane, tower crane, mast crane.
According to the driving mode: a type of centralized drive, that is, a motor drives a long drive shaft to drive both sides of the active wheel; The other is driven separately, that is, the driving wheels on both sides are driven by a motor. Medium and small bridge crane more use brake, reducer and electric unit synthesis of "three-in-one" driving mode, large weight ordinary bridge crane for easy installation and adjustment, the driving device often uses universal coupling.
According to the structural form, the crane is mainly divided into light and small lifting equipment, bridge type (bridge type, gantry crane), arm type (self-propelled type, tower type, gantry type, railway type, float type, mast type crane), cable type.Light and small lifting equipment is characterized by light, compact structure, simple action, operation scope projection to point, line. Light, small lifting equipment, generally only one lifting mechanism, it can only make a single lifting movement of heavy objects. Belonging to this category are: jack, block, hand (gas, electric) hoist, winch, etc. Electric hoist is often equipped with running trolley and metal frame to expand the scope of operation.
