Innovation In Roof Lifting

CribPost System

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.

A system that accommodates EVERY situation

  • Lift to ANY desired clear height without costly staging. Do NOT limit the efficiency of your expansion to double the original clear height.

  • Extend height with a new column or short insert. NOT limited to unsightly sleeves around old columns.

  • Can raise the roof even where columns are not present. Does NOT require a new column to be installed when none are required.

  • No under-slab work required.

  • Can increase bay sizes when necessary by removing existing columns.

  • Continuous fall-back protection at every inch.

  • Can lift at a rate of up to a foot per hour.

  • Laser monitored control of entire lift.

  • Synchronized central control system ensures even lifting and no damage to existing framework and roofing.

We at Polaris were very amazed at the efficiency and dedication exhibited by your employees. This dedication contributed greatly to a successful project completed ahead of schedule. Rooflifters personnel were always concerned not only for the safety of their own employees but also were very attentive to Polaris employees who were in the area while all the preparation for the lift was taking place.

When we’re working with an incumbent building, height restrictions can sometimes prevent us from utilizing the full capabilities of our equipment. Finally there’s a way to avoid the capital costs of reconstruction or a new building.

I was speaking with a real estate agent who was bemoaning the fact that he couldn’t sell an industrial building because of its low ceiling, …and one thing led to another.

One of the reasons companies are moving is they’re looking for modern buildings elsewhere, with greater height underneath the joists. If we can persuade a company to raise the roof to allow for more warehousing space, so they don’t need to relocate outside Toronto, then we’ve saved jobs and taxes.

Ronald Rea, Toronto Economic Development

If we were to turn that whole building into rubble and start fresh, it would cost a whole lot more money than it’s costing to just raise the roof and fix it up. We’re just lifting the roof and adding steel.
