About our spider cranes

BOB-LIFT BLS3.0T spider crane with its outriggers spread in our factory

A spider crane is a compact crane that stands on several outrigger legs instead of a truck. It is built for narrow or awkward work areas, indoors or outdoors, where a truck crane cannot drive in or set up.

BOB-LIFT offers two spider cranes: a knuckle boom version and a telescopic boom version. The knuckle boom version can reach over or around obstacles, while the telescopic version gives a straight, direct reach. Both are built in our Xuzhou factory, which exports to 120+ countries. Spider cranes of this type are typically used for glass and panel installation, building maintenance and lifting inside halls or courtyards.

To get the right setup, tell us the heaviest load, the working radius and height, and the narrowest doorway, corridor or lift the crane must pass through. Check the ground where the legs will stand, and read the load chart for the radius you need. If the site has truck access, compare our truck mounted cranes as well.
