BH-45 – 4,500 lb. Deluxe Flat-Plate Boat Hoist

The BH-45 – 4,500 lb. Deluxe Flat-Plate Boat Hoist combines an Elite 1 HP Painted Wired Boat Lift Motor and an 6,500 lb. Deluxe Gear Plate Assembly to create a boat hoist.

The 6,500 lb. Deluxe Gear Plate Assembly include the 10-inch aluminum die-cast hoist pulley, 96-tooth cast iron worm gear assembly, extended block bronze worm assembly and 34-inch drive belt.

There are no steel-on-steel moving parts. It has been assembled and tested by the manufacturer. Lifetime warranty included. You can choose between galvanized steel, 1/4 in. aluminum, 1/2 in. aluminum or powder-coated steel for the backplate. This item ships in a single box.

Elite 1 HP Painted Wired Boat Lift Motor are single-phase motors with start capacitors. Standard duty motors. Factory-wired for 220 volts. An electrician can rewire it to 110 volts. Fits all BH-USA flat-plate hoists and gear plates. Fits other brands using the standard 4 ft x 2 ft flat-plate mounting holes.

NEMA 56 frame motor. UL/CSA listed and approved. TENV (totally enclosed, non-ventilating) housing. TENV housing prevents dirt, insects, and water from entering the motor.

Maximum runtime: 15 minutes. Finished in black. Includes colored T-wires. Includes easy-to-follow instructions. Equipment guide and wiring instructions included.

A motor wire harness is installed directly on the electrical motor. Depending on your preference, you can select a maintained (lock-on) or momentary (spring-loaded) drum switch type. The in-line GFCI has a built-in test and reset button.

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.

Gear plates from the Deluxe Series feature cast iron 96 tooth worm gear assemblies and extended block bronze worm assemblies. For the Deluxe series, we use motors up to 1 horsepower.

It is BH-USA’s recommendation to hire a licensed electrician for wiring or rewiring electrical components.

3,500 lb. Deluxe Flat-Plate Boat HoistNever use the same material for both worm gears. The use of steel-on-steel or bronze-on-bronze is not recommended for flat-plate hoists.
