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. |
