Above the safety bolt 20, a millimeter scale 24 is placed, which in combination with the centimeter scale 43, renders the exact suppor height of the hydraulic sheeting support.With the lock on the upper cylinder of the hydraulic sheeting support, the uncontrolled falling out of the upper cylinder 40 from the operational cylinder 18 is prevented.With the option of installing exhcangeble upper pedestals 47. It is possible to elevate (and support) various load forms, and using the separate incline adjustable lower pedestals of the hydraulic sheeting support 50, it is possible to install the same on inclined and uneven surfaces.
