FAQ: Panel Lifting

The TCA Technical Committee provides answers to common questions about Tilt-Up construction as well as some tips and techniques.


Where can I obtain information on necessary crane rigging, sling lengths, boom length and spreader bars?

The rigging configuration, spreader bar length and sling lengths are specified in the erection booklet prepared by the erection designer. The crane size and boom lengths are determined by the crane company.

At what phase of the job should I plan the erection sequenced?

Before the panels are cast, have the crane company representative assist in the layout to ensure that the panels can be lifted in the sequence cast.

What safety precautions are necessary before and during lifting?
  • Provide the crane company with a set of panel lifting details well before the day of lifting so that they can plan necessary rigging.
  • Double-check that the rigging configuration and that the spreader bars and slings are the correct length.
  • Watch for ditches, holes and overhead obstructions that might prevent the crane from moving.
  • Have a safety meeting at the beginning of the erection to ensure that everyone knows what is expected and how to operate safely.
  • Make certain everyone on the rigging crew knows how the lifting hardware is supposed to work.

About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
