Electric Overhead Crane

Electric overhead crane is important overhead lifting equipment, and it is widely used for indoor and outdoor lifting work. It adapts to many occasions, such as workshop assembly, overhaul, and maintenance, garage maintenance, metallurgy factory, iron and steel plant, and dock goods lifting and transferring.

Main Parts and Accessories of Electric Overhead Crane

The crane mainly comprises main beam, end beam, end truck, hoist or trolley traveling track, bridge drive, lifting mechanism, control system and so on. Lifting mechanism is the most important and basic mechanism for the crane, and its working performance affect that of the overall crane. The lifting mechanism generally includes drive device, wire rope winding system, extract device and safety protection device and so on; the drive device consists of motor, reducer, brake, drum group and coupling; the wire rope winding system includes wire rope, drum group, pulley block and hook group;  the extract device consists of hook, eyebolt, grab, electromagnetic chuck and other hoisting tool; the safety protection device mainly contains overload limiter, lifting height limiter, over speed protection switch and safety brake.

The bridge frame is the main force mechanism of the crane, and it can adopt single girder single track or double girder double track structure; main girder and end girder are the main force part, and there are trolley track, walking platform, railing and ladder for double girder crane. The main girder adopts normal box structure and the main force material is Q235B, which can make sure the crane has enough strength, rigidity and stability; the end beam uses box structure and the connection between the main bean and end beam is rigid connection.
