O P E R A - GH   (O G H)

Heavy-Duty Industrial Gear Head Operator With Hoist
25 CYCLES/HOUR  >80 CYCLES/DAY

APPLICATIONS
The Opera-GH is a heavy-duty worm gear industrial operator designed for use on industrial standard, high and vertical lift sectional doors or rolling doors and grilles.

The operator can be wall, hood, or shelf mounted on either side of the door. It incorporates the patented Hoist-a-matic®, a self-engaging chain hoist for manual operation, which simplifies operation and installation.

The operator is available with the new Electronic Control Board (BOARD 070) with or without the option of electrical control for MONITORED external entrapment protection devices (UL325-2010 compliant).

STANDARD FEATURES
Motor:
60Hz high starting torque, continuous-duty, single phase capacitor start or 3 phase motor, open drip proof with enclosed ends or drip cover, protected against overload. Also available with 50Hz 220V 1 phase and 380V 3 phase motor, consult inside sales.

Reduction:
45:1 worm gear in oil bath reducer with air breather and sealed ball bearings. Output shaft is 1" with 1/4" keyway up to 1HP, 1-1/4" output shaft with 1/4" keyway above 1HP. Output shaft speed: 38 rpm.

Drive:
#50 roller chain with a 50B12 sprocket for the operator drive shaft. Door sprocket selected for a door travel of 6"/s to 12"/s.

Hoist-a-matic® self-engaging hoist (floor level engagement device is not required to operate) for manual chain operation. An electrical interlock automatically disconnects power to the motor operator when the the chain hoist is engaged. Hoist on right is standard, but it can be easily moved to the left in the field.

Electrical Enclosure:
All electrical components are in a Nema 1 enclosure. Hinged electrical enclosure cover.

Limit System:
Rotary-type oil-impregnated steel cams, commercial grade switches. Limit shaft is supported by self-lubricating bronze bushings for increased precision. Remains in time when there is a manual operation or after the motor has been removed.

Accu-cam® Feature:
Precise and quick one-handed adjustment of the limits.

Corrosion Protection:
Reducer, control enclosure and frames protected by baked on, long lasting enamel finish. Polymer control box cover. Limit and hoist shaft protected by yellow chromate coating.
