ADAPTABLE SUPPORT DEVICE WITH STEP-WISE RELATIVE POSITIONING

摘要

FIELD: personal use articles.SUBSTANCE: device contains multiple vertical actuating mechanisms positioned on bridge modules installed across and above the cavity so that to enable movement relative one another. The invention is as follows: the device contains two double groups of hydraulic cylinders positioned between every two bridge modules. Each group contains two hydraulic cylinders with varied operating stroke, oriented in opposite directions and connected to each other with back sides of their heads, which allows each two modules to move relative each other step-by-step with installation in four fixed positions depending on which cylinders are actuated.EFFECT: device improvement.6 dwg
