Liftmaster TDC22X4BMC Extended Duty Gate Trolley

Product Description

The LIFTMASTER TDC22X4BMC is an extended duty trolley designed for use in commercial and industrial gate control applications. The trolley serves as the drive mechanism that connects the gate operator motor to the gate itself, transferring power to move the gate along its track. Extended duty construction means this component is built to handle higher cycle counts and greater mechanical stress than standard-duty alternatives. Licensed gate system installers and commercial door technicians are the primary professionals who specify and install this part.

This trolley is intended for gate controller systems requiring a robust, high-cycle trolley assembly. Extended duty trolleys are commonly found in commercial access control installations such as parking facilities, industrial yards, and gated communities where gates operate at elevated daily cycle counts. The unit of measure is each, sold individually.
