Single head unpowered suction lifting equipment is more suitable for work without hydraulic power supply and is very suitable for working in special operating environments.
No need to install, the sucker ring can be directly connected with the crane hook.
Rely on the slack and tension of the chain to control the vacuum generation and release, and complete the suction and release operations through the vacuum control valve.
No need for any control buttons, no need for any external power, not affected by power failure or insufficient voltage.
Since there is no need for external wires or air pipes, the equipment can be moved to any place with lifting equipment to work, and the equipment can rotate freely 360 degrees.
Only when the workpiece is put down and the chain is completely slack, the workpiece can be released. There will be no misoperation, so the safety is extremely high.
