The Lifting Industry’s next generation lifting hooks

Advancing Workplace Safety

NDL hooks incorporate the company’s patented, double locking mechanism. An innovative safety feature that independently, and automatically, locks the hooks mechanism on two opposing axis to ensure load integrity is maintained at all times, effectively eliminating known equipment related risks and associated hazards of unplanned hook openings or hooks self-releasing the load.

A safety initiative to improve safety in the Offshore sector where lifting equipment is subjected to the unpredictable, sometimes abnormal, forces generated by the hydrodynamic nature of the marine lifting environment.

NDL hooks set a new, industry wide, standard for lifting hook intrinsic safety and integrity.

As secure as a shackle, much easier and quicker to use, the advanced NDL hooks combine functionality with simplicity, significantly improving operational safety in the lifting environment.

  • Simple, easy thumb activation required to unlock the hook
  • Clever combination between the integral safety handle and side-mounted actuator provides an ergonomic "rotational" wrist action to open and discharge the hook
  • Unique operating motion that eliminates the wrist bending action (strain) required to operate traditional safety hooks
  • Added leverage provided by the patented safety handle gives the hooks a very light fee to control or operate
