Designed for easy operation and installation, Harrington's&#174; 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.

Standard control voltage is 24V. Strain relief wire is molded to pendant cord for added support and dependability. E-Stop is standard on all pendants</li><li>Extreme Duty Motor: Increased performance through 30/10-minute duty rating, H4 classification, Class B insulation, cooling fins and external thermal motor protection</li><li>Load Sheave: Five deep-groove pockets fully support the load chain during operation.
