Harrington’s unique SEQ model hoist is a DUAL SPEED VFD, 1-PHASE electric chain hoist with re-connectable 115/230V power. This hoist also includes 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. Mount the SEQ hoist to our PT push or GT geared trolley to transport any load. Our SEQ hoist is a true REVOLUTION in SINGLE PHASE lifting!
