All ANVER VT Vacuum Tube Lifters can be equipped with a release assist valve, model VT-RAV-M-CV for the Mini size lifters and VT-RAV-S-CV for the Standard size lifters. The VT-RAV-M/S-CV valve will aid in the release of any load, and is especially useful when handling loads that require extra effort to break the vacuum seal when attempting to release the load. The VT-RAV-M/S-CV is recommended for use with multi-pad vacuum tube lifters equipped with articulating extended length handles.
Principle of Operation:
The operation of the lifter for attaching and lifting the load is the same as for a standard lifter without this feature.To release the load, once the load is in its release position, fully depress the control lever, and tilt up the pad attachment to break the seal. If the seal cannot be broken in this manner, pull and hold the RED release knob while holding the control handle down. Once the seal is broken, and the load is released, release the control handle and the RED release knob, and the lifter will rise up. Once the lifter is clear of the load, reposition the vacuum lifter to its working height.
