●The gripper plate is very thin, it can be easily intruded into the bottom of the weight for lifting heavy objects.
●It is most practical in a narrow situation where large cranes cannot work.
●High efficiency, safe and convenient.
●The spring can be automatically retracted.
●The machine should put on a flat place when using , and avoid deflection
●It is strictly prohibit the lifting height more than the product requirement limit , or else leading to the Guide fall off from the machine.
● Forbid the overload operation.
