Clamping device for lifting equipment with clamps

technical field

The utility model belongs to the technical field of lifting equipment, and relates to a lifting equipment for lifting with clamps, in particular to a clamping device for lifting equipment for lifting with clamps.

Background technique

Lifting equipment refers to the electromechanical equipment used to carry or move heavy objects. Most lifting equipment starts a vertical or vertical and horizontal working stroke after retrieving the material. After reaching the destination, it unloads and then travels empty to the reclaiming location Complete a work cycle, and then carry out the second lifting or handling. Generally speaking, when the lifting equipment is working, the retrieving, moving and unloading are carried out in sequence, and the work of each corresponding mechanism is intermittent; Bulk materials such as , ore, grain, etc., can be used to lift liquid materials such as molten steel after being equipped with a bucket; some lifting machinery such as elevators can also be used to carry people. Lifting equipment is a very important work machine, for example, cranes for loading and unloading materials in ports and stations are the main work machines.

Clamp lifting equipment is a kind of lifting equipment that is convenient for loading and unloading. It has the advantages of high efficiency and convenient use. It is not necessary to manually pack and tether the goods, so it can save manpower, save time and improve efficiency; the clamping device of the clamp lifting equipment is the core component of the clamp lifting equipment.
