Zusammenfassung: | To provide an over-inclination correction unit of an elevating scaffold which enables correction of over-inclination of a scaffold with a simple structure and at low cost.SOLUTION: An over-inclination correction unit of an elevating scaffold consists of a first and a second mast parts, erected with a predefined space in between, a first moving part 5 and a second moving part 6, freely movable along the mast parts 1 and 2 respectively, and a carrier part 7, set as bridging over both moving parts 5 and 6 for carrying workers. There are plural dogs 28 arranged vertically at even intervals on each mast part 1 and 2, and a first and a second limit switch 25 and 26, arranged in each moving part 5 and 6, for detecting position of a dog 28. When the carrier part 7 elevates as both moving parts 5 and 6 move up and down, for instance, if a first limit switch 25 detects one of the dogs 28, a control moving part 31 stops the first moving part 5 with the first limit switch 25 temporarily.SELECTED DRAWING: Figure 9
【課題】容易な構成でかつ低コストで作業床の過度の傾斜を補正する昇降式足場の過傾斜補正装置を提供する。【解決手段】本発明は、所定の間隔を隔てて立設される第1のマスト部1及び第2のマスト部2と、両マスト部1,2に沿ってそれぞれ移動自在な第1の移動部5及び第2の移動部6と、両移動部5,6に掛け渡されるように支持されるとともに作業者が搭乗する搬器部7と、を備える。各マスト部1,2に上下方向の等間隔にそれぞれ設けられた複数のドグ28と、各移動部5,6にそれぞれ設けられ、いずれかのドグ28の位置を検出する第1及び第2リミットスイッチ25,26とを備え、両移動部5,6の移動による搬器部7の昇降時に、例えば第1リミットスイッチ25がドグ28のいずれかを検出したとき、第1リミットスイッチ25が設けられた方の第1移動部5の移動を一時的に停止させる移動制御部31を備える。【選択図】図9 |
