STANDARD FEATURES

• Motor:
1/2 HP, 115V single phase intermittent-duty motor with instant reverse and internal automatic reset thermal overload protection. Removable without affecting limit switch settings. Also available with 50Hz motor, consult inside sales.

• Reduction:
First step in reduction 5L/B V-belt drive, additional steps by chain and sprockets. Input shaft is 5/8", supported by precision ball bearings. Output shaft is 1" with 1/4" keyway, supported by ball bearings. Output shaft speed: 36 rpm.

• Clutch:
Friction type, positioned on input shaft, easily adjustable from outside.

• Drive:
#41 roller chain with a 41B12 sprocket for the operator drive shaft. Door sprocket selected for a door travel of 6"/s to 12"/s.

• Brake:
Mechanical brake.

• Manual Operation:
