< Specification >

1. No need to install, the sucker ring can be directly connected with the crane hook.

2. 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.

3. No need for any control buttons, no need for any external power, not affected by power failure or insufficient voltage.

4. 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.

5. 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.

< Advantages >

Unpowered Sucker is a device that uses the principle of pneumatic pressure to realize adsorption and fixation, compared with the traditional powered sucker(which need to be driven by an external power supply), it has the following advantages:

Save Power and Energy: 

Do not need external power supply, do not consume electricity, save energy costs, reduce the cost of use.

Easy to Operate:

Easy to use, no wiring and power supply, only through the pneumatic pressure control can realize the adsorption and release operation, simple and fast operation.

Safe and Reliable: 

Do not involve electrical components, to avoid electrical failure and safety hazards, the use of more safe and reliable.

Low Maintenance Cost:

The structure is simple, with few parts, low maintenance cost and long service life.

Strong Flexibility:

Suitable for various working conditions and environments, without being limited by power supply, more flexible and convenient.

Environmental Protection and Energy Saving:

Do not produce electromagnetic radiation and noise, in line with environmental requirements, friendly to the environment.

Unpowered sucker adopts advanced adsorption technology, its strong adsorption force can be firmly fixed on a variety of smooth surfaces, to ensure that the lifting process is stable and reliable, greatly improving work efficiency. Choosing unpowered sucker makes lifting easier, safer and more efficient! Let's enjoy the fun of lifting together, finish the work easily and create a better future!
