摘要

The device has actuation units (3) on bridge piles for installing platform. Each unit has a fixed support (10) and mutually superposed leveling wedge (18) and slider (21). The wedge and slider execute cyclic alternate movements under an action of jacks (30, 31). The slider rises with the platform, moves with the platform in a longitudinal direction and is lowered by resting the platform on the support during the cyclic movements.
