Double-girder bridge crane parts
The LD single-girder eot crane (E-Bridge Crane) is designed to provide an efficient lifting solution for light and medium-duty applications. It utilizes a single girder as the bridge's main beam and features a trolley that moves along the beam to lift the load. Driven by an electric motor system, it delivers smooth and precise lifting operations.
Its compact design makes it suitable for environments with limited headroom or space constraints, such as factories, workshops, and warehouses. It is ideal for lifting small and medium-sized loads efficiently and at low operating costs.

Single-girder double-hoist overhead cranes utilize a box girder or I-beam as the primary load-bearing structure, with two electric hoists (typically wire rope hoists or chain hoists) mounted on the same main girder. Load capacities typically range from 5 to 20 tons (single hoist) or 10 to 32 tons (double hoist combined), with spans ranging from 5 to 22 meters. Their simple structure reduces manufacturing and maintenance costs compared to double-girder cranes. Their light weight makes them suitable for applications with height restrictions or limited load-bearing capacity.
