The PowerMaster 02-44000 GT-104 is a 1HP, 230/460V, 3-phase gearhead trolley operator engineered for heavy-duty commercial and industrial sectional doors. Its gear-driven design delivers strong lifting power, precise motion control, and long-term reliability, making it ideal for demanding applications requiring consistent performance.
With its robust gearhead drivetrain, the GT-104 provides superior mechanical strength and reduced wear compared to standard trolley operators. It is built for high-cycle environments such as warehouses, manufacturing plants, distribution facilities, automotive service centers, and commercial buildings where durable overhead door automation is essential.
The GT-104 integrates easily with modern access control systems, monitored safety devices, and automation accessories, ensuring a complete and secure overhead door solution.
