To provide an engagement chain type lift which can maintain a push-up load of an engagement chain irrespective of a lift stroke by suppressing an inclination and buckling of the engagement chain.SOLUTION: An engagement chain type lift 100 of this invention comprises a chain guide mechanism 130 for supporting an engagement chain 120 which is constituted so that a pair of chain members 121A, 121B are engaged with each other, and integrally rigidified in self-standing states while being freely branched from each other due to mutual disengagement so as to be liftable in a prescribed position in a vertical direction. The chain guide mechanism 130 comprises: a pair of support bodies 131 arranged at a pair of guide rails 108 for leading and guiding a lift body 101, and guiding a lift of the engagement chain 120 from at least both sides of the engagement chain 120 in an engagement direction; and a movable mechanism 140 for moving a pair of the support bodies 131 between a support position and a retreat position in which a lift of the lift body 101 is not hindered.SELECTED DRAWING: Figure 1
【課題】噛合チェーンの傾斜や座屈を抑制して噛合チェーンの押上げ荷重を昇降ストロークに無関係に維持することのできる噛合チェーン式昇降機を提供すること。【解決手段】本発明の噛合チェーン式昇降機100は、一対のチェーン部材121A,121Bが相互に噛み合って自立状態で一体に剛直化するとともに相互に噛み外れて分岐自在となるように構成された噛合チェーン120を鉛直方向における所定位置にて昇降自在に支持するチェーンガイド機構130を備え、チェーンガイド機構130が、昇降体101を誘導案内する一対のガイドレール108の各々に設けられ少なくとも噛合チェーン120の噛合方向両側から噛合チェーン120の昇降をガイドする一対の支持体131と、一対の支持体131の各々を支持位置と昇降体101の昇降を妨げない退避位置との間で移動させる可動機構140とを備えた構成とされる。【選択図】図1
