Hung overhead suspension cranes Cranes can be single, double or triple span. The main advantages of these cranes - small dimensions in height, the possibility of installation in separate areas of the shop, covering large spans.
The crane bridge is a load-bearing I-beam, which is attached to the lower parts of the end beams. The lifting mechanism is a mobile hoist.
To increase the service life of running wheels and suspended tracks, the connection of the supporting beam with one end beam is made movable, as it gives the possibility of changing the span of the crane, which facilitates its self-installation on the tracks, when passing the crane curved sections of suspended tracks. The wheels of the travelling trolleys are freeboard and the side rollers are mounted on the ends of the end beams and contact the side surfaces of the walls of the I-beams of the suspension track.
The overhead travelling crane is supplied for operation indoors, under a canopy or outdoors (1, 2, 3 according to GOST 15150). It can be operated from the floor or by radio channel.
