China Motor Driven Single Beam Overhead Crane

Motor Driven Single Beam Overhead Crane
Part 1: Description

LD type single girder overhead cranes typically consist of a single girder construction. These can be built with steel beams or more rigid welding box girder type. Single Girder Cranes is
more typical when lifting capacity less than 20T
LD Single Girder Overhead cranes are widely used in our industrial field. It is applied at steel plant, Hydropower Plant, Warehouse, Workshop, Production Line, Maintenance Shop, Material
Transportation, Equipment Assembly Shop etc. We have Comprehensive standard equipment and wide range of accessories to suit individual requirements
