The CribPost system is best described as a series of temporary hydraulic post-shores that can be extended to nearly any reasonable height.
Each post is built up with bolted sections. The bottom of the post is contained within a frame that holds a 25-ton capacity hydraulic jack which pushes the post upward and allows new sections to be added at the bottom as lifting progresses. This allows us to accommodate any clear height without the added cost of moving the lifting mechanism up the column and welding on additional steel.
All hydraulic work is done at ground level, the hydraulics are not suspended from a location 15 or more feet off the ground, which ensures the safety and speed of all hydraulic work.
