Our SEQ hoists are the industry’s first dual speed via VFD, single phase electric chain hoists. The variable frequency drive furnishes smooth starts and stops, adjustable speeds, and unbeatable precision. The added benefit of a no-load high speed function that automatically increases hoist speed up to 130 percent when the load is less than 30 percent of working load limit takes lifting to new heights.
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.
Die-cast body is lightweight and offers low headroom – one of the best in the industry. Paint is electrostatically applied.
Provides quiet and smooth guiding of chain. Heavy cast iron construction for improved wear versus stamped steel design offered by many manufacturers.
Equipped with an electromagnetic pull rotor brake, the SEQ has no brake coil to fail or discs to replace, making it virtually maintenance free.
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.
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.
