Technical Field
[0001] The utility model relates to the technical field of working tools for working at heights, in particular to a connecting rope for a fall arrester. Background Technique
[0002] A fall arrester, also called a speed differential device, is a protective product that can quickly brake and lock a falling object within a limited distance. It is suitable for cargo hoisting, protecting the lives of ground operators and preventing damage to the lifted workpiece. Most personnel who need to work at heights need to connect to the fall arrester through a rope before the operation to ensure the personal safety of the operators.

Since the hook of the fall arrester is too high, a rope needs to be used for connection. A direct connection with a single rope will occupy the space of the loading position and is likely to hang on the oil tanker, leading to accidents. Therefore, we propose a connecting rope for a fall arrester. Content of the Utility Model
