in the third step, after the device is used, firstly, the rope and the pull ring (17) are unfastened, the second motor (36) is driven to withdraw the rope, the retracting wheel (32) is wound up, then the locking bolt of the driving mechanism (28) is loosened, the driving mechanism (28) is removed, then the first roller (14) and the second roller (19) are detached, the bracket mechanism (8) can be separated from the support (2), the bracket mechanism (8) is removed, the locking bolt of the support (2) is loosened, the support (2) is separated from the chassis (1), after the support (2) is laid down, the cross beam (6) and the reinforcing rib plate (4) are detached, then the detached device parts are loaded on a car, and detachment is completed.
