LiftMaster MT5011 Replacement Parts — MT and BMT Medium-Duty Trolley Operators

Genuine LiftMaster replacement parts for the MT and BMT medium-duty trolley operators. The MT5011 is by far the most common version — 1/2 HP, 115V, single phase. The BMT is the braked version of the same machine; the brake components shown in the dashed boxes on the diagram fit BMT models only.

Your model number is on the operator’s data label. The first two digits after the letters are horsepower and the last two are voltage, so MT5011 is 1/2 HP at 115V and MT5025 is the 230V 50Hz export version. A U or E after the number is the logic board type. Electrical box parts are further down this page, split by logic control and mechanical control. Parts marked no longer available have been discontinued by the manufacturer and are listed for identification only.
