Rope Gripper is responsible
for the safety of our customers.
Rope Gripper ™ is an over speed protection device that protects passengers from the risk of injury due to failure of the brake control system of the elevator, breakdown of the brake, and failure of the component that determines the car speed in the ascending or descending direction. If the elevator car door is open due to slipping or if it exceeds the rated speed, it will stop the car safely by catching the main rope of the elevator when sudden rise or fall.

01
Using a spring moving along the fixed cam
It has the mechanical advantage of using a spring that moves along the fixed cam, so it can grab the main rope strongly but smoothly so that excessive pressure or damage can not be applied to the main rope of the elevator without modifying the machine or hoisting machine sheave or other devices.
02
It is possible to prevent accidents when the slipping phenomenon of the traction machine occurs.
When the slipping phenomenon of the traction machine occurs, the accident can be prevented. This cam action is designed to compensate for lining wear and spring drooping so that constant pressure is applied to the elevator rope, even if the spring force is reduced to less than half the original.
