Variable Frequency Drive (VFD)

All dual speed 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.

COMPACT ALUMINUM BODY

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 of chain. Heavy cast iron construction for improved wear versus stamped steel design offered by many manufacturers.

Self-Adjusting Maintenance-Free Brake

Equipped with an electromagnetic pull rotor brake, the EQ has no brake coil to fail or discs to replace, making it virtually maintenance free.

HIGH SPEED WITH NO LOAD

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.

Extreme Duty, Single-Phase, Fan-Cooled Motor

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.
