PROBLEM TO BE SOLVED: To provide a lifter device equipped with a push-up auxiliary mechanism which comprises a linkage and which can elevate a loading table in association with telescopic motion of a link.SOLUTION: A lifter device comprises a push-up auxiliary mechanism 26 in which a tip 17 of a chain 16 is fixed to a loading table 2, the other end thereof is fixed to a winding shank 22 of a drum 15 which is rotated by a motor 20 with a speed reducer, an intermediate part of the chain 16 is wound on a sprocket 18 which is attached to at least one place of a movable side shaft which constitutes a linkage 3 and wound on the winding shaft 22 of the drum 15 by rotation of the drum 15 thereby elevating the loading table 2, and even from the state that the loading table is lowered, the loading table can be easily elevated.SELECTED DRAWING: Figure 2
【課題】 リンク機構を備えて該リンクの伸縮動に伴って載置台が昇降動することが出来る押上げ補助機構を備えたリフター装置の提供。【解決手段】 チェーン16の先端17を載置台2に固定し、他端を減速機付きモータ20にて回転するドラム15の巻付き軸部22に固定し、そしてチェーン16の中間部をリンク機構3を構成する可動側軸の少なくとも一か所に取付けたスプロケット18に巻き掛けし、ドラム15を回転することで該ドラム15の巻付け軸部22に巻付けることで載置台2は上昇し、そして載置台が降下した状態からでも容易に上昇出来るように押上げ補助機構26を備えている。【選択図】 図2
