8,500 LB. BHUSA Gear Plate Assembly- Powdercoated



12679: 8500 lb Advanced Dual Pulley Gear Plate Assembly- Powdercoated


The 8,500 lb Advanced Dual Pulley Gear Plate Assembly features a solid aluminum worm housing, extended support blocks, easy-to-reach grease fittings, and composite bronze backplate bearing. No steel on steel moving parts. The 8,500 lb plate has a single worm gear with a hardened steel worm and solid bronze 96 tooth worm gear. Rated for 8,500 lb capacity. The motor is not included.

Assemblies include the 10-inch aluminum die-cast hoist pulley, 96-tooth bronze worm gear assembly, extended block bronze steel assembly, and 34-inch drive belt.

The extended block worm assembly has a 2-inch bearing block, a worm on a driveshaft, and an aluminum housing with 1/4 inch grease fittings. Attaches directly to the gear plate. The assembly has standard flat-plate mounting holes.

The 96 tooth worm gear assembly comes assembled with the gear, sleeve, backplate bearing, axle sleeve bolt, and snap rings. 1/4 inch easy-reach grease fittings are included. The gear fits standard gear plates used in flat-plate hoists.

The 10 in. Aluminum Die-Cast 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.

The AX-34 is a 34-inch drive belt that is compatible with all flat-plate boat hoists from BH-USA. This belt is the perfect length to fit around a 10-inch hoist pulley and to be able to attach it to a 2-inch motor pulley. As the motor’s driveshaft turns, the pulleys turn the belt in order to complete the movement of the hoist.
