Harrington’s SMRQ Series dual speed motorized trolley coupled with our SEQ Series single-phase dual speed electric chain hoist are a true revolution to the industry. Dual speed is achieved in the hoist and trolley via VFD for precise lifting and moving needs.
All models come with a standard “under-the-cover” variable frequency drive – regardless of voltage. This device works by varying the power to the motor, which allows you to adjust both the high and low speeds. It also provides a soft-start/soft-stop operation to reduce shock loads, swing, and bounce – resulting in more precise load control and longevity of the hoist.
Provides quiet and smooth guiding of chain. Heavy cast iron construction for improved wear versus stamped steel design offered by many manufacturers.
Equipped with our pull-rotor motor brake, the SEQ has no brake coil to fail or discs to replace, making it virtually maintenance free.
When working with less than 30% of the full rated capacity, the SEQ can operate 1.3 times faster, optimizing your work efficiency and production time.
Drop stops and rubber bumpers not only provide additional security for the operator, they also protect the equipment against collisions.
