A small gantry crane can be equipped with a micro electric hoist, wire rope electric hoist, or chain hoist. If the customer has a 380 volt power supply, they can choose a three-phase chain hoist. The small gantry crane is also known as: portal crane - simple gantry crane, simple gantry frame, portable simple gantry crane, portable hand-pushed gantry frame, and crane. By matching different models of universal brake casters, it forms a mobile column-type gantry crane frame. This type of gantry crane frame has a lifting capacity of 1-3 tons, generally with a width of 3 meters and a height of 3 meters.
