Heavy Duty Head Jacks

With unusually high horizontal forces to accommodate WorkZone Scaffolds knew that this project would be technically challenging.

Located in Lower Hutt, just north of Wellington, the Naenae Regional Bowls Centre commissioned WorkZone Scaffolds to provide a heavy duty propping scaffold. The purpose was to temporarily support the installation of a 46m wide permanent fabric roof over a new artificial green. The cost of the project was $6.25 million.

Heavy duty scaffolding components

Kurt Simpson, WorkZone Scaffolds Project Manager, said “problem solving was a big aspect of this project. We had a lot of engineering issues to work out!”

Measuring up to 6m wide and 12m long, the scaffold reached a maximum height of 10m and required Layher’s heavy duty propping components to be used in conjunction with its Layher Allround Modular scaffolding. The main propping column consisted of eight Layher Allround scaffold standards, joined using twin wedge couplers, heavy duty base jacks and U head jacks.

Technical calculations

Layher helped with design concept and technical calculations. Kurt said “the support received from the Layher Engineers was top notch. With such high loads and small tolerances the propping solution needed to be 100% accurate”

Kurt continued “the client was impressed with the solution and professional service provided by WorkZone on the project.”
