Features
The NVC-H has the built-in safety latch that prevents a work piece from slipping due to the initial clamping force caused by the spring even if the wire rope becomes loose during the operation.
How to use
- Insert a steel plate into the inside end of the clamp's jaw opening and then lock the safety latch.
- Clamp the center of gravity of the work piece in order to equally distribute the weight of the work piece.
Warnings
- Do not exceed the rated capacity specified on the clamp.
- Use a work piece only which falls within the jaw opening range specified in the instruction manual.
- Never lift two or more work pieces with one clamp.
- Lift a work piece only after checking the biting location and the biting condition of the work piece, and the proper functioning of
the safety latch.
-When lifting a work piece, a signal man must be outside the rotation radius of a work piece to send a signal to a crane operator.
