▪ Save labor and greatly improve the efficiency. Ih efficiency with grab= 80h efficiency of 16 workers without grab.
▪ Improve production safety and greatly reduce the personal injury accidents

3. Mechanical grab
Mechanical grab itself no configuration retractable roof structure, usually driven by ropes or the connecting rod force, according to the operating characteristics can be divided into four rope grab and single rope grab, the most commonly used is the double rope grab.
Four wire rope grab reliable work, convenient operation, high productivity, wide application.
Single rope grab rope and support the opening and closing of a wire rope with rope. The winding mechanism of single rope grab is relatively simple, but low productivity, rarely use a large number of loading and unloading operations.
