PROBLEM TO BE SOLVED: To enable the reduction of a cycle time when lifting a carriage between travel paths having different vertical heights.SOLUTION: A carriage lifting device comprises: lifting platforms 4a, 5a for supporting and lifting a carriage 1 between an elevating limit height corresponding to an upper side travel path 2 and a lowering limit height corresponding to a lower side travel path 3; and carriage drive means for transferring and moving the carriage 1 between the lifting platforms 4a, 5a and the upper and lower travel paths 2, 3. The lifting platforms 4a, 5a are divided into a plurality of lifting units 52-54 that are arranged serially in a direction of the transfer and movement of the carriage 1, and one carriage 1 is supported by the plurality of lifting units 52-54. Lifting drive means 55-57 are provided together with each of the lifting units 52-54, and thereby the plurality of lifting elements 52-54 can be lifted at different timing separately.

    【課題】上下高さの異なる走行経路間で搬送台車を昇降させるときのサイクルタイムを短縮出来るようにする。【解決手段】上側走行経路2に対応する上昇限高さと下側走行経路3に対応する下降限高さとの間で搬送台車1を支持して昇降する昇降台4a,5aと、この昇降台4a,5aと上下各走行経路2,3との間で搬送台車1を乗り移り移動させる搬送台車駆動手段を備えた搬送台車昇降装置において、前記昇降台4a,5aは、搬送台車1の乗り移り移動方向に直列する複数台の昇降単体52〜54に分割して、1台の搬送台車1を当該複数台の昇降単体52〜54によって支持するように構成し、これら各昇降単体52〜54に昇降駆動手段55〜57を併設して、これら複数台の昇降単体52〜54を各別に且つ異なるタイミングで昇降させることが出来る構成。【選択図】図12
