Product Overview

LH double-girder crane with electric hoist consists of box-shaped bridge, trolley travelling mechanism, crab and electric equipment. lt employs fixed electric hoist which is fitted on crab frame as hoisting mechanism. The crab uses LD drive to run, while the trolley adopts LD drive or QD drive. It has three operation modes:ground handle,wireless remote control and cab.The cab has two types: open cab and closed cab.

A compact designed crab unit for the medium load capacity range, with articulated end carriage joints ensuring positive contact

of all four wheels with the track, with two direct drive cross travel motors. Load capacity range: 3 ton to 32 ton.
