Designed for easy operation and installation, Harrington’s MRQ Series dual speed motorized trolley paired with our EQ Series three-phase dual speed electric chain hoists are the answer for lifting and moving material in medium- and heavy-duty industrial applications. Both hoist and trolley are dual speed via VDF so you can fine tune speed to meet your 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.
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.
Equipped with our pull-rotor motor brake, the EQ has no brake coil to fail or discs to replace, making it virtually maintenance free.
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.
Drop stops and rubber bumpers not only provide additional security for the operator, they also protect the equipment against collisions.
