Designed for easy operation and installation, Harrington’s MRQ Series dual speed motorized trolley paired with their 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.

• Variable Frequency Drive (VFD). This device works by varying the power to the motor, which allows you to adjust both the high and low speeds
• Die-cast body is lightweight and offers low headroom – one of the best in the industry. Paint is electrostatically applied.
• Unique Chain Guide provides quiet and smooth guiding
• Equipped with Harrington's pull-rotor motor brake, the EQ has no brake coil to fail or discs to replace, making it virtually maintenance free.
