The RoboSwing is our most advanced swing gate operator for single family residences and residential complexes up to 15 units. Designed for super-quiet operation, it can handle up to 250 cycles per day (when used with a plug-in transformer) with gates weighing up to 400 lbs. and up to 16 feet in length.Unlike other systems, the Robo Swing is designed with a ''non-scissor action'' swing arm to greatly reduce the risk of injury. What's more, the system features a DC motor with a 12-volt, 7-amp hour battery for dependable operation, even when the power goes out. Plus, this system helps to simplify installation by allowing installers to use low-cost, low-voltage wiring or an optional solar panel for operator use in remote locations.
