Specific introduction to the non-powered suction crane

　　The working principle of the self-priming vacuum lifting machine is described as follows: The vacuum generator of the vacuum lifting machine includes a sealed cylinder and a freely movable piston. There is a movable air sealing diaphragm between the piston and the cylinder. The sealing effect of the sealing diaphragm is not achieved through metal friction or interference fit, so it does not lose effectiveness during use.

　　The vacuum suction and release cycle is completed by the active circulation valve at the bottom of the piston. When the vacuum lifting machine is placed on the surface of a heavy object and the chain is slack, the cam automatically opens the piston valve. When the chain pulls the piston upwards, a strong vacuum is generated inside the cylinder and the vacuum suction cup. When the heavy object is completely lowered, the chain becomes slack again.

　　The cam closes the piston valve, and the internal vacuum is released. Then, the vacuum lifting machine is lifted, preparing for the next adsorption. The suction and release occur instantaneously. Because the cam only switches actions when the chain is completely slack, it cannot switch the piston action during use, thus avoiding the generation of *.

　　The non-powered vacuum lifting machine company’s cantilever crane plays a very important role as an indispensable part of the entire equipment. According to the usage scenarios and requirements, we provide customers with two types of cantilever cranes: aluminum alloy track cable-stayed type and folding arm type, with a design coefficient of 1.4 and a safety factor of 5. Through structural optimization and lightweight design, these two types of cantilever cranes are far ahead of other brands in terms of technical level, craftsmanship, and quality.
