[0001] The utility model relates to the technical field of fall arresters, in particular to a collision-resistant safety fall arrester. Background Art
[0002] A fall arrester can quickly brake and lock a falling object within a specified distance, preventing injury from falling objects or personnel. It is suitable for cargo hoisting, protecting the lives of ground operators and preventing damage to the hoisted workpiece. There are three main types of fall arresters: wooden tankway fall arresters, steel rail tankway fall arresters, and brake rope fall arresters.
