[Features]

  • NHC-HL has the built-in safety lock(spring) 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]

  • When the jaw opening gets wider by pushing the cam down, insert a work piece into the inside end of the clamp’s jaw opening.  Release the cam and then the safety lock will be automatically locked
  • Clamp the center of gravity of a work piece in order to equally distribute the weight of the work piece.

[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.
  • Do not vertically lift work pieces with horizontal clamps.
  • Never lift narrow work pieces.
  • Never lift bendable work pieces.

[Features]

  • Due to the safety lever, the NVC-L is convenient to use and also easy to separate the clamp after working with thick steel plates.
  • After releasing the lever, the link stops functioning even if the shackle is lifted. Therefore, it is easy to do the biting and releasing work.

[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.

[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.
  • Ensure that during the operation, the lever does not collide with other objects since the safety lever is attached to the exterior of hte clamp.
  • 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 rotation radius of a work piece to send a signal to a crane operator.
