Single girder electric hoist bridge crane is composed of bridge frame, trolley, cart operating mechanism and electric equipment and is applicable for the workshops, freight yards and warehouses in stations, ports and mining enterprises, hoisting, transporting and loading all kinds of materials in the fixed spans.
According different environments and purposses, the crane can derives many models such as low speed, explosion proof, insulation, electromagnetic, bucket grab, double trolleys and dual purposes, and triplicate purposes
Capacity of 1----32t and a span of 10.5m-35.5m. Lifting height 1---100m
we have top running and under running bridge crane, can meet your different requirements
Top Running vs. Under Running
Top Running vs. Under Running is primarily determined by two factors:
- Capacity - Although under running can be up to 25 ton capacity, the practical limit is more like 15 tons and the economic sweet spot is 1 to 7.5 ton range.
- Support Structure - Under running can be suspended directly from the overhead steel (for lighter cranes). Top running cranes will require a bracket off the building support steel (up to 10 tons capacity) or independent columns for heavier capacities
