About This Operator

Right-Sized Hoist Power

The MH delivers hoist-operator capability at medium-duty scale: wall-mounted beside high or vertical lift sectional doors and small rolling doors and grilles, rated for 12 cycles per hour and under 50 per day. It’s the practical choice for service bays, small warehouses, and commercial buildings that don’t need industrial cycling. Its chain hoist with electric interlock allows safe manual operation in an emergency — the interlock cuts power while the hoist is engaged, protecting both staff and machine.

Good to Know

MH — Common Questions

Where does the MH fit best?Smaller, lighter commercial doors with mid-range duty needs — wall-mounted on high or vertical lift sectional doors and small rolling doors and grilles.
What’s the electric interlock for?When the chain hoist is engaged for manual operation, the interlock cuts operator power — preventing the motor from running while someone is on the chain.
How many cycles can it handle?A maximum of 12 cycles per hour and fewer than 50 cycles per day. Busier doors should step up to a Logic 5.0 industrial operator.
Do you stock parts?Yes — we carry motors, limit switches, and hoist parts for the medium-duty line for fast turnarounds.
