This explosion-proof geared trolley was developed by Hengying Special Lifting Equipment. It is a lightweight handling device with a simple structure and convenient hand-chain operation. Combined with a hand chain hoist or electric chain hoist, it forms a travelling lifting unit. It runs on the lower flange of an I-beam track, including curves within its specified radius, and can be installed on straight or curved overhead monorails or manual single-girder, overhead and jib cranes.
