Existing fall arrest safety ropes typically use spring-loaded buckles for their connecting parts, which cannot effectively lock into the fixed rope, resulting in insufficient safety.
The device employs a sliding assembly and a clamping assembly. The sliding assembly slides on the fixed rope to adjust its position via first and second rollers, while the clamping assembly uses a handle to drive a cam so that its top surface abuts against the fixed rope to achieve a clamping effect.
The clamping effect between the fall arrest safety rope and the fixing rope has been improved, increasing safety.
