Abstract: The carriage decking device comprises four deck maneuver rails arranged in pairs and opposite one another, and connectors, connected at the deck maneuver rails, and which are capable of sliding up and down along the deck maneuver rails. A certain number of positioning holes are axially distributed on the deck maneuver rails. Yokes are connected on external sides of each connector, and partitions are fastened between the yokes. A depressed mounting cavity is provided on the internal side of each yoke, and a stop pin is provided inside the mounting cavity. A connecting hole that aligns with the stop pin is provided on each connector, and the stop pin extends into the connecting hole. A clutch that enables the stop pins in the mounting cavities to connect with the positioning holes of corresponding deck maneuver rails or to detach from the positioning holes simultaneously is provided between two neighboring yokes.

Abstract: A winch with an anti-locking structure comprises a support and a worm wheel, the two sides of the worm wheel are provided with a ring-shaped left positioning boss and a ring-shaped right positioning boss which protrude outward, the left positioning boss is sleeved with a left positioning sleeve, the right positioning boss is sleeved with a right positioning sleeve, and the outer circumferential surface of the left positioning boss is gaplessly sleeved with a circular hole wall of the left positioning sleeve, the outer circumferential surface of the left positioning sleeve is gaplessly sleeved with an inner hole of the case body, the outer circumferential surface of right positioning boss is gaplessly sleeved with a circular hole wall of the right positioning sleeve, the outer circumferential surface of the right positioning sleeve is gaplessly sleeved with the inner hole of the case body.

Abstract: A chain load binder comprising a housing and a sprocket setup in the housing. A worm, a spline shaft, and a worm gear meshing with the worm are also designed within the housing. The sprocket is opposite the worm gear and both ends of the spline shaft are connected to the worm gear and the sprocket respectively. The housing comprises the left half housing and the right half housing connecting to each other. The left half housing is made of non-metal solid material, where the worm and the worm gear are fixed; and the right half housing is made of rubber, where the sprocket is installed. Both ends of the chain stretch out of the bottom of the right half housing. There is an inner steel plate installed inside the right half housing, attaching to its inner surface.
