Rockstop (2)

Product description

Jackpots are single-use hydraulic jacks which are placed on top of timber props and then inflated with high-pressure water through a non-return valve. Under pressures of 120 to 140 bar they expand axially and load the mine props to between 20 tonne and 50 tonne, locking the props into place and applying pressure against the rock mass.
