10 in. Aluminum Die-Cast Dual Belt Hoist Pulley
The 10 in. Aluminum Die-Cast Dual Belt Hoist Pulley is made from an aluminum die-casting process. Over 15 years of use on BH-USA Flat Plate hoists. They are much stronger in marine environments. They will not swell or bend. The belt-gripping technology on the inside of the pulley prevents belt slippage. Compatible with any known flat-plate hoist. Resistant to warping. Designed to fit drive belts better. The bore is 3/4 inches. Accepts belts up to 1/2 inch.
Worm gears are mounted on the gear plate at the top mounting holes. An assembly block is installed around the middle of the gear plate to match up the gear. When the assembly block’s drive shaft rotates, the worm gear inside the assembly block turns the 96-tooth gear. There is a pulley mounted on the drive shaft of the assembly block, and there is a smaller pulley mounted on the drive shaft of the motor, which is mounted at the bottom of the gear plate. On both pulleys, a belt is installed. The motor rotates its drive shaft in response to the motion of the pulleys on the motor and assembly block, which then turn the worm gear inside the assembly block, which turns the 96 tooth gear. A drive pipe installed through the 96 tooth gear’s bore causes the drive pipe to rotate. If the motor is turning in one direction, or the other, the drive pipe will either raise or lower whatever is attached to it.
