Taller masts can be difficult to mount onto a vehicle due to the longer retracted lengths involved. Our Roof Trolley Systems provide a solution that allows masts up to 30m extended height to be fitted to a wide range of vehicles. The roof trolley system carries the mast in a horizontal position in a frame on the vehicle roof. To deploy, the mast is rolled back and tilted to a vertical position and locked into place. An air hose is then attached and the mast is ready for extension. For more information
