Introduce the working principle of the vacuum suction crane.

　　The vacuum lifting machine (commonly known as the elephant trunk vacuum lifter) is a fast, safe, and convenient automated device. It uses the principle of vacuum adsorption, employing a vacuum pump or vacuum blower as the vacuum source to create a vacuum at the suction cup end, thereby securely lifting various workpieces and transferring them to a designated location via a reversible mechanical arm.

　　The vacuum lifting machine is almost omnipotent: whether you need to stack boxes, load barrels onto a truck, handle metal sheets or wood in a warehouse, or transfer stones or furniture—using a vacuum lifting machine will always be your best transfer solution. Transferring with a vacuum lifting machine is faster, more ergonomic, and safer.

　　For those who need to move heavy objects, investing in a vacuum lifting machine is an investment in health. It eliminates diseases such as joint injuries caused by labor from lifting heavy objects, thereby improving employee motivation and production quality. Objects are lifted using only one power source, without the need for other power sources such as cranes, mechanical arms, or hydraulic cylinders.

　　The operator only needs to use the control handle to adjust the vacuum level of the system. The more vacuum there is, the higher the object is lifted; the less vacuum there is, the more slowly the object is lowered. Its high lifting speed can reach up to 70m/min. The quick-start unidirectional safety valve, combined with a large-area vacuum suction cup, ensures that the lifted object will not fall when there is a power failure.
