成したことを特徴とする作業台昇降装置。[Claims for Utility Model Registration] A workbench is mounted on a base via an It consists of upper and lower telescoping booms arranged to be able to come in and out, the upper end of the upper telescoping boom being pivotally connected to the work platform, the lower end of the lower telescoping boom being pivotally connected to the base, and between the base and the intermediate boom. In the work platform elevating device in which the work platform is raised and lowered by an interposed telescopic cylinder, a first synchronization mechanism is provided in each of the intermediate booms to synchronize the amount of expansion and contraction of the upper and lower telescopic booms, and a first synchronization mechanism is provided between each of the pair of intermediate booms. A second synchronizing mechanism between the two intermediate booms is interlocked with the first synchronizing mechanism.
A work platform elevating device characterized in that a tuning mechanism is provided, and each tuning mechanism is constituted by a winding transmission means.
