T-style trolley commercial door operators are optimal for general
industrial applications. Suspended from the ceiling, the operators are
used on sectional overhead doors with standard lift. T operators are directly
attached to drive and control the door.
SECURITY+ 2.0 RADIO RECEIVER - Standard on-board with Logic 5.0 operators.
- Accepts up to (90) single-button or (30) 3-Button remote controls plus up to (30) wireless keypads or an unlimited number of DIP switch remotes.
MOTOR - Continuous-duty high-starting torque motor with instant reverse and overload protection.
- Available in 1/3, 1/2, 3/4 and 1 HP; single- or three-phase.
- Capacitor start on single-phase.
- Removable without affecting limit switch settings
WIRING TYPE - Operators are factory preset to C2 wiring, providing momentary contact to open and stop, with constant contact to close.
- Monitored entrapment protection, using approved photo sensors or sensing edges is optional, although recommended, when using C2, D1 or E2.
- All other wiring types, B2, T, TS and FSTS can be selected with the addition of an appropriately monitored entrapment protection device (LiftMaster CPS-U photo eyes, LiftMaster OES monitored sensing edge, or a monitored sensing edge supported by the CPS-EI, as examples).
- Logic 5.0 operators can only accept UL-Approved LiftMaster monitored entrapment protection devices.
CONTROL CIRCUIT DRIVE REDUCTION - First-stage heavy-duty 5L V-belt; second #41 chain; #48 (for 1/3 and 1/2HP) and #41 (for 3/4 and 1HP) output chain on trolley
BEARINGS - Industrial ball bearings on output shaft, heavy-duty oil-filled bushings on reduction shafts
BRAKE - Standard on 3/4 and 1 HP operators (optional on 1/2 HP, not available on 1/3 HP).
CONSTRUCTION - NEMA 1 type electrical box, heavy-duty 11-gauge steel frame with durable powder coat finish, all reduction sprockets drilled and pinned to shafts.
TROLLEY ROLLER CHAIN - #48 on 1/3 and 1/2 HP.
- #41 on 3/4 and 1HP.

FLOOR LEVEL CHAIN HOIST WITH ELECTRICAL INTERlock
- Provides easy disconnect and manual operation in an emergency.
HEAVY-DUTY WORM GEAR-IN-OIL GEAR REDUCER
- Delivers performance for heavy industrial, high cycle applications.
CONTROL FUNCTION SELECTOR DIAL
- Enables easy selection and programming of (7) wiring types, from constant pressure to close, to specialized Timer-to-Close functionality to meet end-user needs.
TIMER-TO-CLOSE
- Conveniently and confidently closes the commercial door automatically after a predetermined amount of time has elapsed for added security and peace of mind.
CONTINUOUS-DUTY HIGH-STARTING TORQUE MOTOR
- Performs in demanding industrial overhead and rolling door applications.
MOTOR REMOVABLE WITHOUT AFFECTING LIMIT SWITCH SETTINGS
- Saves time and money for maintenance.
MID-STOP
- Enables partial opening of door to a pre-programmed position for energy savings, time savings, and convenience.
MAXIMUM RUN TIMER
- Reverses or stops door if closing time exceeds expected time-frame to limit damage to door and operator.
DELAY-ON-REVERSE CIRCUIT
- Prevents abrupt reversal of door, reducing wear on the door and operator system.
3-BUTTON CONTROL STATION WITH MAINTENANCE ALERT SYSTEM (MAS)
- Provides open/close/stop functions and notification when routine maintenance is required.
