[0002] Gantry stacker reclaimer is a heavy-duty mechanical equipment specially used for material reclaiming operations. It is widely used in coal, ore, bulk cargo terminals, electric power, chemical and other industries. This equipment can efficiently carry out material reclaiming operations in large open-air yards or warehouses through its unique gantry structure design.

[0003] The existing gantry type stacker and reclaimer drives the grab claws with grabbing function to move horizontally and vertically on the track, so that the grab claws can approach the material pile at a faster speed to pick up the material, and then grab the material with the grab claws to transfer the material, so as to pick up the material. However, during use, the material moved by the gantry type stacker and reclaimer is generally heavy, and may produce a certain degree of shaking due to the inertia of movement when being grabbed and moved by the grab claws, and the grab claws generally only grab the material from the horizontal direction.
