Hydrocell Pre-Stressing Plate

Hydrocell Pre-Stressing plate is a welded, expandable sheet metal plate used for pre-loading support props and cribs. Hydrocells fill with water from a hose or pump and expand to apply load to the roof. Hydrocells are capable of supporting up to 10 tons of installed load.
INSTALLATION

Hydrocells are placed above the roof support, below the wedges (if used) and headboards. Using a pump or hose, the Hydrocell is filled with water and expands to apply pressure upward on the roof. Hydrocells are capable of supporting up to 10 tons of installed load.
