TELESCOPIC TOWER
To suppress a swinging movement due to lifting and improve installation workability.SOLUTION: A telescopic tower 1 includes a base frame 10, a movable frame 20 capable of moving against the base frame 10, a projection portion 41 provided in the movable frame 20, a pair of guide plates 42 provided on the base frame 10, and a positioning mechanism 50 that positions the projection portion 41 to the guide plate 42. The positioning mechanism 50 includes a plurality of through holes 51, a positioning hole 53, a temporary stop groove 55 provided at a tip end of the guide plate 42, a first pin 56 penetrating the first through hole 51A and arranged across the pair of the temporary stop grooves 55, and a second pin 57 penetrating the through holes 51 other than the first through hole 51 and the pair of the positioning holes 53 and arranged.SELECTED DRAWING: Figure 8
【課題】吊り上げによる揺れ動きを抑制し、設置作業性を向上する。【解決手段】伸縮式タワー１は、基枠１０と、基枠１０に対して移動可能な可動枠２０と、可動枠２０に設けられた突出部４１と、基枠１０に設けられた一対のガイド板４２と、ガイド板４２に対して突出部４１を位置決めする位置決め機構５０とを備える。位置決め機構５０は、複数の貫通孔５１と、位置決め孔５３と、ガイド板４２の先端に設けられた仮止め溝５５と、第１貫通孔５１Ａを貫通して一対の仮止め溝５５に跨がって配置された第１ピン５６と、第１貫通孔５１以外の貫通孔５１及び一対の位置決め孔５３を貫通して配置された第２ピン５７とを有する。【選択図】図８
