Abstract
A movable barrier operator (200) comprises a motor (201) having an output drive shaft that itself comprises a first end (202) and a second end (203) that is disposed opposite to the first end. The movable barrier operator also comprises a hand-operated chain hoist (204) that is connected to the second end of this output drive shaft. By one approach, the movable barrier operator also comprises a reduction mechanism (207) and a transmission (210). The reduction mechanism is disposed parallel to and laterally of the motor and comprises a movable barrier drive output (208) and an input drive shaft (209). The transmission, in turn, is disposed to couple the first end of the output drive shaft of the motor to the input drive shaft of the reduction mechanism.
