Abstract
The present invention concerns a telescopic mast which at least includes one or more telescoping joints, where a telescoping joint consists of two telescoping sections dimensioned so that one section can be moved into another section, where between each of 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 overlapping each other when the telescopic mast is collapsed.
Claims9
A telescopic mast including at least one or more telescoping joints with parallel walls, where one of two adjacent telescoping sections is narrower than the other of the two adjacent telescoping sections, so that one telescoping section can be moved into and out of, respectively, of a second telescoping section in a telescoping section as well as the second section may be moved into and out of a third telescoping section in a further telescoping joint, where between each of two adjacent telescoping sections in a telescoping joint there is provided at least one actuator, preferably several actuators, adapted to urge the adjacent telescoping sections away from each other, where these actuators are disposed internally of the telescoping joints, wherein actuators in the telescopic mast are mutually offset at the internal periphery of said telescopic mast, and that at least one actuator and preferably several actuators mounted in a telescoping joint are completely independent of one or more further actuators which are mounted in one or more further telescoping joints or in the same telescoping joint, where said actuators are gas springs.
