<p>The present invention relates to a telescopic moveable tower, wherein rectangular telescopic steel cages ascend by means of pulleys by winding steel ropes around the drum or drums via a worm gear reducer. It has the features of locking itself in case the rope breaks or comes loose, can be stopped at the desired point, and the cages can be fixed to each other if desired at the point of elevation. While our telescopic tower can be used as a tower crane by mounting a boom thereon, it can also be used as a telescopic moveable scaffold by mounting a working platform thereon</p> |
