DJB-WNN wall-mounted cantilever crane, the cantilever is made of H steel and the lower support structure. It can be used on reinforced concrete walls or factory building columns. The lifting height can be determined arbitrarily according to the site requirements. The decisive advantage of the wall-type cantilever crane is that it saves space on the ground columns and is simple to install. The ready-made standardized bracket saves a lot of complicated calibration work. The wall-mounted jib crane is suitable for a load range of up to 3000kg and a maximum cantilever length of up to 10m.
