Screw clamp for hanging the hook of a lever block when building vessels and manufacturing(attachment and press) construction plants and also for horizontal lifting during the press process.

NPC-A Screw Clamp

· How to use

Insert a steel plate into the inside end of the clamp's jaw opening and then completely tighten the screw.



· Application

A screw clamp for hanging the hook of a lever block when building vessels and manufacturing(attaching) construction plants.

· Features

The NPC-A is a screw clamp used to prevent accidents caused by the widening, slipping or breakage of the hook because the load is concentrated at the end of the hook when hanging the hook of a lever block and a chain block directly on a work piece.

The NPC-A is a safe clamp designed to prevent a work piece from slipping as the jaw opening of the clamp gets smaller by the slope which is proportional to the load on the spherical swivel jaw built in the jig bearing which works as gearing on the opposite side of the screw

· Warning

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.

If the load is placed laterally, not straightly, on the eye hole, use only 1/2 of the rated capacity.

Never vertically erect a work piece with this model.

For horizontal lifting, the clamping point must be two or more. When clamping, the clamps must face each other, not look in one direction.
