The box grabbing process of the trolley spreader: when the trolley spreader needs to descend to grab the box, the trolley spreader descends without load, and the trolley spreader drives the lifting drum a1 to rotate forward through the lifting wire rope, and the trolley spreader drives the lifting drum a1 to rotate forward. The rising potential energy of the counterweight a5 is mainly provided by the falling potential energy of the trolley spreader, and the energy consumption of the lifting reel is mainly used to control the descending speed of the trolley spreader. When the trolley spreader descends to the container , the balance weight rises to the limit position, and the lifting reel stops forward rotation;

The lifting reel reverses, the trolley spreader grabs the box and rises, and the balance weight drops to release energy. At this time, the energy consumption of the lifting reel is mainly used for lifting the container, and the lifting of the spreader itself is controlled by The counterweights provide energy.

For those of ordinary skill in the art, other changes or changes in various forms can also be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the protection scope of the present utility model.
