The number of the balancing weights can be adjusted according to the weight of the lifted goods.

The X, Y axle direction of chassis is square, and the upper portion center is equipped with the stand, and the stand passes through the pull rod in four directions and is connected with four angles of chassis, makes the rigidity of stand strengthen. The four corners and the center of the lower part of the chassis are provided with traveling wheels which can be pushed by manpower or by a maneuvering scheme. The travelling wheel is also provided with a locking device, so that the locking device can be released before hoisting, a machine is moved, and the travelling wheel is convenient to take place. And locking the locking device in the hoisting process, and relatively fixing.

When the power device is used, the assembled machine is put in place, the travelling wheels are locked, and then the power device is powered on. The rotating arm is rotated to enable the lifting hook to reach the position of the lifted goods, the goods are hooked, the lifting key is pressed to lift the goods, the key is stopped after the lifting key reaches the target height, then the rotating arm is rotated to be in place, the descending key is pressed to place the goods, and a cycle of operation is completed.

The utility model discloses mainly be applicable to in the civil engineering construction operation of goods loading and unloading car and lower height, have that the dead weight is light, convenient to carry, the equipment moves a plurality of advantages such as dress swift, nimble flexible, be indispensable practicality machinery in operations such as commodity circulation center, storage storehouse, rural house-built, it can alleviate workman's the labour bitter, can improve work efficiency again, practices thrift the operating cost.
