SEQ

When voltage is limited, you don't have to be.

Welcome to the SEQ family of powered hoists: smooth starts and stops, adjustable speeds, and unbeatable precision. Fitted with a Variable Frequency Drive and with single phase power, the SEQ is where safety and performance meet innovation.

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.

Seq%20chain%20guide

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.

Kito52134 adjusted

Self-Adjusting Maintenance-Free Brake

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

No-Load High Speed

When working with less than 30% of the full rated capacity, the SEQ can operate 1.3 times faster, optimizing your work efficiency and production time.

Cooling%20fan%20seq

Extreme Duty, Single-Phase, Fan-Cooled Motor

Rated for an ASME H4 Classification, the motor has a 30/10 minute duty rating in a single phase, dual speed offering. The external motor fan functions quickly to eliminate resistor, motor, and brake heat.
