T Trolley Operator

Logic 5.0 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.

  • MyQ Technology enables you to securely monitor and control your facility door operator and lights with your smartphone, tablet or computer for greater peace of mind.
  • Alerts can be received as email or pop-up (push) notifications.
  • Control function selector dial allows for easy selection and programming of (7) wiring types, from constant pressure to closer 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.
  • Mid-stop enables partial opening of door to a preprogrammed position for energy savings, time savings and convenience.
  • Dual voltage connections increase flexibility by enabling the Installer to select the required voltage within phase to meet job-site requirements. Within phases, voltage is selectable at the time of installation with the placement of a connector.
  • Continuous-duty high-starting torque motor with instant reverse and overload protection. Capacitor start with single phase, removable without affecting limit switches.
  • Adjustable friction clutch helps to protect door and operator from damage should the door meet and obstruction.
  • 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).
  • Drive reduction, first stage heavy-duty 5L V-belt; second #41 chain; #48 (for 1/3 and ½ HP) and #41 (for ¾ and 1 HP) output chain on trolley.
