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.
When working with less than 30% of the full rated capacity, the EQ can operate 1.3 times faster, optimizing your work efficiency and production time.
Rated for an ASME H4 Classification, the motor has a 30/10 minute duty rating in a three phase, dual speed offering. The external motor fan functions to quickly eliminate resistor, motor, and brake heat.
Perfect for traversing a load when electric power is not necessary or available. Harrington’s GT geared trolleys can be paired with almost any Harrington hoist.
