Safe anchoring with magnetic anchor points

With McNetiq Controlock® anchor points a scaffold can indeed be securely anchored: lean and mean, only where required and many buttresses can be omitted. The result: savings of 40% on lead time and 70% on materials. Shell

The pilot project with McNetiq Controlock scaffold anchoring: Contractor Bilfinger offered the Controlock® technology to build four scaffolds against ethylene tanks at Dow Chemical in July 2013. See both technical drawings below This produced considerable savings for the chemical company. For detailed information, please refer to the Case study scaffolding saving money with magnetic anchors by Dow →. Since then, other scaffold projects have also been successfully completed. See the testimonials and the photo gallery below. 

Savings for scaffolding


Traditional scaffold

  • 2,100 m³
  • 20 tons of material
  • 20 tons of ballast


Scaffold with Controlock® technology 

  • 275 m³
  • 6 tons of material
  • no ballast


How to use a magnetic scaffold anchor point

Based on the pre-made and pre-defined design, the scaffold is built on site. One of the members of the construction team must be certified for the application of the McNetiq Controlock Scaffold Anchor. This Controlock operator will always arrive with his equipment on site where anchoring needs to be applied according to the design. The operator positions the magnetic anchor and measures the effective tensile and shear force of the anchor at the specific location. If he can determine the measurements required and recorded in the design, he will finally secure the anchor and wil connect it to a scaffold ledger. Then he will move on to the next positioning.

Measuring shear force and tensile force.

Building a scaffold with magnetic anchor points will be explained step by step in this instruction video →

In collaboration with magnet producer SAV Walker Hagou a manual  has been produced for the use of magnetic scaffold anchor points.

Suspended scaffolds

It is possible to anchor scaffolds, that are not built up from the ground, at the location where acces is desired. Especially in shipbuilding and maintenance it can offer a solution to create a work platform without any welding work on the hull. See the photos in the Photo Gallery and the model drawings of the suspended scaffold against a ship wall. (PDF) →
