[Features]

Due to the safety lever, the NVC-LB is convenient to use and also easy to separate the clamp after working with thick steel plates. Since the lever is attached to the inside of the clamp, there is a lower possibility of damage by the mid-air collision of clamps.
Even for a high working place, it is easy to separate the clamp from the ground by connecting a rope to the safety lever.

[How to use]

Insert a steel plate into the inside end of the clamp's jaw opening and then lock the safety lever.
Clamp the center of gravity of the work piece in order to equally distribute the weight of the work piece.
When pulling the rope to release, pull it lightly with wrist snap.

[Warnings]

Do not exceed the rated capacity specified on the clamp.
Lift 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 lever.
When lifting a work piece, a signal man must be outside the roattion radius of a work piece to send a signal to a crane operator
