Hydrocell Pre-Stressing Plate
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.
Hydrocells are available in different sizes. The load produced is directly related to the size of the plate.
- Pressure required to open inlet valve for inflation is 29 psi
- Relief valve releases at 290 psi
- Normal expansion is between one & three inches
