AI Technical Summary

Technical Problem

Existing cable anchoring systems cannot effectively absorb impact when the lifting device moves suddenly, leading to rapid cable wear and requiring frequent and expensive maintenance.

Method used

A rotatable drum with a variable bending radius structure on its side surface was designed, allowing the cable to travel a large distance during winding and unwinding, while the spring absorbs the impact force to prevent cable wear.

Benefits of technology

This allows for a large cable travel distance within a limited space, reducing wear and tear and lowering maintenance frequency and costs.

Abstract

The present invention relates to a reel (1) suitable for anchoring a cable (3) to a frame (2), the reel (1) being adapted to be rotatably mounted on the frame (2) about a rotation axis (X), the reel (1) having a side surface (S) about an axis (Y) parallel to the rotation axis (X), the reel (1) being characterized in that the side surface (S) includes a first portion having at least a first bending radius measured in a plane (P) perpendicular to the rotation axis (X), the first bending radius being substantially greater than at least a second bending radius of a second portion of the side surface measured in the plane (P), the reel (1) being adapted to allow the cable (3) to travel by winding and / or unwinding the cable (3) along the first portion about the side surface (S) and by rotating the reel (1) about the rotation axis (X) between a first stop position and a second stop position.
