Linear OSCO LRA Swing Gate The Linear/OSCO LRA Linear Residential Actuator is designed to open and close a light-duty residential swing gate. The operator can be used in left‑hand or right‑hand swing gate installations on gates weighing up to 600 pounds. The operator is connected by a cable to an APeX electronic controller, which provides all connections for input and entrapment detection devices. The Controller is housed in a separate enclosure and contains a built-in radio receiver for wireless activation by remote control transmitters. Brackets attached to the gate and gate hinge post are for mounting the operator and to provide a mechanism to move the gate. When the operator activates, the worm drive in the linear actuator changes the distance between the two brackets that the operator is mounted on. When the operator pulls the two brackets closer together, the gate opens. When the operator pushes the two brackets farther apart, the gate closes. Click here for an application example.
