Repairing a Building's Foundation after an Earthquake

Customer

Sync Lift Systems Ltd. New Zealand

Location

Christchurch, New Zealand

Challenge

After a devastating earthquake, a 2,800 ton city center building was knocked off its foundation and needed to be lifted and leveled by up to 300 mm.

Solution

An EVO Synchronous Lifting System was used to manage the lifting force and extension of 22 high tonnage double-acting CLRG-Series hydraulic cylinders to safely and accurately lift the foundation and building to the required position. Each cylinder was installed in a steel stool which was connected to the buildings foundation. Draw wire stroke sensors were attached to each of the lifting positions, providing displacement information to maintain synchronous accuracy of all positons to less than 1 mm. Managing the lifting operation from one central control system improved safety and operational productivity.
