GH 5HP Heavy Industrial Gear-Reduced Hoist Parts

LiftMaster GH 5HP Replacement Parts — Heavy Industrial-Duty Gear-Reduced Hoist Operator

Genuine LiftMaster replacement parts for the GH 5 horsepower gear-reduced hoist operator. Use the exploded diagram to identify your part by its key number, then match it to the tables below.

The 5 HP GH is a different machine from the rest of the GH range. It has its own gear reducer, its own sprockets, its own chain wheel and hand chain shaft kits, and an electrical box that shares no parts with any other LiftMaster commercial operator. If your GH is 1/2 through 3 HP, you want our main GH parts page instead — nothing on this page will fit it.

Your model number is on the operator’s data label and reads GH5HP23M, GH5HP43M or GH5HP53M depending on voltage. The overload in the electrical box changes with the voltage, so check which one you have before ordering that part.

Models Covered

GH5HP23M (230V, 3PH), GH5HP43M (460V, 3PH), GH5HP53M (575V, 3PH) — all 5 HP

The motor’s part number is printed on the motor’s own data label. If you can reach it, read the number straight off the label and match it above — that is the most reliable way to order the right motor.

Electrical box parts. The 5 HP GH uses a dedicated mechanical control box built around a DIN-rail contactor and a thermal overload sized to the motor voltage. It shares no parts with the Logic 4.0, Logic 5.0, NEMA 4 or contactor-style boxes fitted to the rest of the LiftMaster commercial range.
