Aut-o-doR Swinging Gate or Door Operator (Std.) shall be manufactured by Crown Industrial at 213 Michelle Ct., So. San Francisco, CA 94080 Phone (650) 952-5150.

Each swing type electric operator shall be built into a compact unit consisting of an instantly reversing motor, NEMA rated starter, a precision-made speed reduction mechanism with "V" belt and pulleys, a safety friction disc clutch, an emergency release, fully automatic limit switches and a heavy duty crank and connecting arm assembly and a weather resistant cover.

The motor shall have ample reserve power to take occasional overloads.

All gears in the speed reduction mechanism shall be cut gears. Shafts and gears shall be mounted with "long-life" bearings enclosed in an oil-tight housing and operate at all times in grease. The automatic limit switches which stop the gate in the desired open or closed position shall be built on this reduction unit.

The operating levers shall consist of a heavy duty crank and connecting arms. This operator unit shall produce the harmonic motion principle of operation that will start in a gradual manner with high torque increasing to a rapid speed in the middle of the cycle of travel, then gradually slowing down to the stop position. When the operator is in closed position, the arms shall be in a locked position. The crank arm shall be in a locked position. The crank arm shall be driven by a safety friction disc clutch which shall protect equipment in case the gate comes in contact with an obstruction. A disconnecting device shall be provided to allow manual operation.

Guarantee: There shall be a warranty of 1 year after installation. THE WARRANTY DOES NOT LIMIT THE NUMBER OF GATE CYCLES PER HOUR.
