Just like a crab does cross-traveling, A Crab Hoist, a type of wire rope hoist, travels on a double girder overhead crane or gantry crane. It is an electric wire rope hoist mounted on a double rail trolley frame.

The double rail trolley type is our compact standard crab unit for the heavy SWL applications between 1 Ton and 30 Ton. This design is characterised by articulated end carriage joints that ensure positive contact of all four wheels with the track.

His impact construction, low headroom, light weight, modular design, and precise positioning are among other features, all present in the crab hoist, which is produced in accordance with Indian standard
