This gearbox housing is made of solid aluminum and finished with marine-grade paint. The straight-line capacity is 4,000 lbs. Gear ratio 450:1. The gearbox comes factory lubricated with special gear oil. Seals are replaceable. It does not freewheel. Designed with one of the world’s largest worm gear reducer manufacturers. Stainless steel or black finish 1 HP electric motor available. Installation is easy with option hoist mounts. The motor has an in-line GFCI and can operate on 110v or 220v with a control cable of 16 feet from the motor to the plug.
The A-Drive 40:75 Double Worm Reducer Gearbox is a direct-drive gearbox designed with a double worm gear reducer. Featured on the 3,000 lb and 4,000 lb enclosed boat hoists of the A-Drive series. The 3,000 lb A-Drive boat hoist is powered by a 3/4 HP wired motor. The 4,000 lb A-Drive boat hoist is powered by a 1 HP wired motor.
The gearbox housing is made of solid aluminum with a marine-grade finish. The gearbox ratio is 450:1. This gearbox includes bronze-on-steel gears. The enclosed gears are permanently lubricated with BH-USA gear grease. No leaks are guaranteed. Includes cast flange mount for the output shaft. Stainless steel fasteners are used.
This gearbox works on both overhead boat lifts and pile mount boat lifts, provided that the appropriate mounting plate is used. Attaching the direct drive boat hoist to the boat lift drive pipe requires a hardened output driveshaft.
The Elite 1 HP Stainless C-Face Wired Boat Lift Motor is a single-phase, dual voltage motor. Painted black finish. Includes start capacitor. Direct drive mounting pattern. Compatible with our A-Drive direct drive boat hoists.
The Elite 3/4 HP Stainless C-Face Wired Boat Lift Motor is a single-phase, dual voltage motor. Stainless steel finish. Includes start capacitor. Direct drive mounting pattern. Compatible with our A-Drive direct drive boat hoists.
