Side lift crane

A side lifter Crane is a road-going truck or semi-trailer, able to hoist and transport ISO standard containers. Container lift is done with parallel crane-like hoists, which can lift a container from the ground or from a railway vehicle.

Gantry crane

Long popular in Europe, gantry cranes have become a widely accepted alternative to overhead bridge cranes. This type of crane is similar to the bridge crane except that it runs on a runway at the floor level. The bridge is supported by a pAir of rigid steel legs which are carried by a pair of end trucks along the floor level runway. Gantry cranes often costs less than a bridge crane and built to heavy duty Class D specifications, which meet the demands of high duty cycles and multiple

Bridge Crane
