A platform for research: civil engineering, architecture and urbanism
The present invention concerns a telescopic mast which at least includes one or more telescoping joints, where a telescoping joint is formed of two telescoping sections dimensioned so that one section can be moved into another section, where between each of the two adjacent telescoping sections in a telescoping joint there is provided at least one actuator urging the adjacent telescoping sections away from each other, where these actuators are disposed internally of the telescoping joints and offset at the internal periphery. By disposing actuators offset at the inner periphery of the telescoping sections, several advantages are achieved. The actuators are provided at a protected location, and the actuators may be designed with lengths that overlap each other when the telescopic mast is collapsed.
