LDP electric single-beam bridge crane is a bridge crane with the bridge supported on the track by two side beams. The main difference between the LDP single beam and the LD single beam is that the LD is the common electric hoist that operates at the lower end of the main beam (I-beam), while the LDP is a pedestal hoist that is mounted on a trolley and runs off-track on the main beam, similar to an L-type gantry crane.

LDP electric single beam bridge crane advantage is that the car runs smoothly, the same elevation of the big car running track surface, lifting height can be increased by 1.5 to 1.8 meters. The shortage is that the production is more complicated than the hanging process, and the production cost is higher. It is widely used in mechanical manufacturing, assembly, production workshops and warehouses, and its fetching device is usually a hook.
