Heavy Lift & Rigging

Heavy Lift

Liftech provides structural design and review of heavy lift procedures including criteria; lift systems, such as jacking systems and cranes; and various hardware. Projects include nuclear power plants, offshore platforms, blimp hangar repairs, and others.  

Our expertise also includes structural design and review of large land-based and floating cranes. We have helped design and review cranes of capacity up to 12,000 t.  Examples include assistance with the 1,700 t floating crane that erected the major components of the San Francisco-Oakland Bay Bridge self-anchored suspension span and the Bigge AFRD land-based ringer cranes. We have worked on several other specialized, confidential crane systems that have major impacts in their marketplace.

Moving Heavy Objects

We have designed systems for moving dockside cranes and other objects. We are familiar with and design schemes that incorporate dollies and heavy haul trailers, air or Teflon pad skid systems, and Hilman rollers. We design crane move systems that lift and move cranes with little out-of-service time for the crane.
