A dual arm barrier assembly comprising spaced-apart stanchions and a pair of barrier arms pivotally connected to a first stanchion for movement between closed and open positions. The barrier arms have distal end portions immediately adjacent to and out of engagement with the second stanchion when in the closed position during normal operation and when the vehicle is out of engagement with the barrier arms. The first barrier arm in the closed position is at a height corresponding to vehicle's windshield, and the second barrier arm in the closed position is below the first barrier arm and is at a height corresponding approximately to the vehicle's body or frame. The second stanchion engages the barrier arms only when the vehicle presses against barrier arms, thereby securely retaining the barrier arms in the closed position.

Dual arm fortified barrier assembly

The present disclosure relates generally to barrier assemblies, and more particularly, to the coupling of a barrier operator to the barrier that the operator is to move. In one embodiment, a barrier operator coupling includes a wedge member that is fixedly attached to an output shaft of the barrier operator. A housing is brought to bear against a wedge member, and an adjustment device is used to maintain the force between the wedge member and the housing.

Coupling apparatus for barrier assemblies and related methods

A barrier operator moves a movable barrier using a motive source having a movable member, a station, and first and second flexible members. The station includes a drive system operatively coupled to the movable member of the motive source. The drive system includes input and output members. The first and second flexible members each have first and second ends and a portion extending from the station. The first ends of each flexible members are operatively coupled to the movable barrier and the second ends of each of the flexible members are operatively coupled to the output drive system member of the station. Aspects include the first and second flexible members being cable or wire. Other aspects include the output drive system member of the station being a spool. The drive system further includes a gear box operatively coupled to the spool. Other aspects include the movable barrier being a gate or door. Further aspects include the motive member being a 3-phase alternate current electric motor having a motor shaft as the movable member. The electric motor is supplied with 3-phase electrical power having voltage levels less than 65 volts root mean square. Additional aspects include calibration of fully opened and closed positions of the movable barrier, automatically positioning of the movable barrier by the barrier operator, supplying 0 hertz electrical power to the electric motor for heating based upon a temperature threshold, and control of frequency of the electrical power supplied to the motor based according to a continuous function of barrier position.
