Product Description

The hoist double girder overhead crane is a bridge crane with a hoist lifting mechanism mounted on a centrally-driven double-rail trolley, used in combination with a double-girder bridge. The hoist can be either a wire rope hoist or a chain hoist, depending on user requirements. This crane can be custom-designed to meet different site conditions and operational requirements, with multiple accessory options. It is highly efficient for large-scale material transfer in warehouses or storage yards and precise equipment installation or maintenance in confined spaces.

The hoist double-girder overhead crane is ideal for material handling, assembly, maintenance, and loading/unloading in machinery workshops, warehouses, storage yards, and power plants. Designed for versatility, it can efficiently handle a wide range of operations, including transport, assembly, maintenance, and lifting tasks. This crane can also replace conventional double-girder cranes in light textile and food industry production workshops, providing a flexible solution that meets the diverse requirements of different industries and customers.
