PROBLEM TO BE SOLVED: To provide an elevation device which permits the reusing of one elevation device by making the elevation device detachable to a guide rail when being required, bears economical superiority of a device cost because installation of the elevation device at every construction on a high place at all times gets to unnecessary and, at the same time, reduces the number of times of maintenance of the elevation device.SOLUTION: An elevation device includes a housing frame, a moving wheel, a driving pinion roller which is coupled and connected with an engine and an auxiliary roller. Therein, the auxiliary roller is arranged on the upper side of the driving pinion roller while retaining a fixed interval, upon installing operation of the elevation device, the housing frame is inclined to the front side, in the first place, contacting operation of the auxiliary roller is performed from a back surface of a rack rail, subsequently, the housing frame is turned to a vertical attitude so as to engage the driving pinion roller with the rack rail and, upon releasing operation of the elevation device, the housing frame is inclined to the front side, the driving pinion roller is separated from the rack rail and, at the same time, the auxiliary roller is separated from a back surface of the rack rail.SELECTED DRAWING: Figure 1

    【課題】必要なときに昇降装置をガイドレールに脱着可能とすることにより1個の昇降装置を使い回しができることとなり、高所な構造物ごとに常時、昇降装置を装置しておく必要がなくなり装置コストの経済的優位性を生むことができると共に、昇降装置のメンテナンスの個数を軽減したものである。【解決手段】昇降装置は匡体フレームと、移動用車輪と、原動機と連動連設し、駆動ピニオンローラと、補助ローラとよりなり、補助ローラは一定間隔を保持して駆動ピニオンローラの上方に配設し、昇降装置の装着操作時には、匡体フレームを前方に傾動して補助ローラをまずラックレールの背面より当接操作し、次いで駆動ピニオンローラをラックレールに噛合させるように匡体フレームを垂直姿勢とし、昇降装置の離脱操作時には匡体フレームを前方に傾動して駆動ピニオンローラをラックレールから離反しながら補助ローラをラックレールの背面より離反するように構成した。【選択図】図1
