SEQ Production Electric Chain Hoist

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.

Also available in 3-phase power with model EQ.

 

  • 115 Volts
  • 230 Volts

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 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.

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 to quickly eliminate resistor, motor, and brake heat.
