PROBLEM TO BE SOLVED: To provide a wrecker belt recovery system that replaces a conventional fixing system for making a gear bite into with a structure which does not damage a wrecker belt and carries out an automatic recovery like the conventional system.SOLUTION: A wrecker belt recovery system 10 comprises an outer shell 12, a roll 31, a wrecker belt 20, a take-up device 50, and a transmission mechanism 40. The roll 31 includes a hub 30 rotatably attached in the outer shell 12 and inserted into a hole 32 and a pair of pan bodies 38 respectively fitted with the hub 30. The wrecker belt 20 is inserted into the hole 32 of the hold 30 so as not to move and has both ends extended from the outer shell 12, thereby moving between an extensional position and a retraction position. The take-up device 50 feeds the hub 30 with an active force necessary to automatically wind the wrecker belt 20. The transmission mechanism 40 is installed between the take-up device 50 and the hub 30 to vary a take-up speed with a gear ratio. |
