Electric Over Head Crane

An overhead crane consists of two parallel rails seated on longitudinal I-beams attached to opposite steel columns by means of brackets. The traveling bridge spans the gap. A hoist, the lifting component of a crane, travels along the bridge.It consists of foot mounted motors with horizontal gearboxes. It is operated by push-button pendant station, radio remote, or operating cabin mode. In double girder EOT crane, a rotary limit switch is used to calculate the hook traveling and the up and down movement should be controlled accordingly.
