Harrington® EQ dual speed VFD 3-phase electric chain hoists are designed for medium to heavy-duty industrial and workstation applications. These hoists include a unique no-load high speed function that automatically increase hoist speed up to 130% when the load is less than 30% of working load limit. 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. Die-cast body is lightweight and offers low headroom-one of the best in the industry. Paint is electrostatically applied. 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 EQ 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 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.
