What is SiteCover

SiteCover is designed as a permanent building that is easy to assemble and meets the production standard for towercranes.
SiteCover is:

  • Not a permanent building although it is designed according to Eurocode in all aspects.
  • Not a tent, since it carries the full design loads for both wind, snow and cranes.
  • Not a tower crane although it is produced according to Execution Class 3

Designing SiteCover

The SiteCover structure is designed to withstand the same design loads as a permanent building. It can carry a full load of snow on the roof, with the cranes still being operateable. 

The structures stability against wind loads is tested in a wind tunnel, which concludes the design to maximise its stability in high velocity winds.

The SiteCover legs consist of an outer- and an inner shell. The legs are mounted with ladders inside and outside, for easy access.

The legs are telescopic with a reach of 16 to 27 meters.

The pyramid shaped roofstructure breaks the windflow passing over the structure better than a saddle roof, reducing the uplift. Placing the steel structure on the outside and membranes underneath also reduces excelled wind speeds over the structure.

The base of SiteCovers steel structure is placed on a 2.4∗2.4 concrete base. The concrete base gives stability during assembly and serves to distribute the vertical loads from the steel structure to the ground. No additional foundation is needed.

The overhead crane is specifically designed to move fast. The crane is costumizable by the costumer: number of cranes, lifting capacity, and the position of cranes. The configuration pictured shows a 27m wide crane with 2, 5 ton hoists, capable of lifting 10 tons in conjunction.

The SiteCover structure it stabilized only by using torque rigid joints. No bracing is used. Choosing torque rigid joints as the main method of stability, means that the amount of steel going in to the structure is much higher than e.g a steel hangar structure. The benefit of this design is the ability to distribute the loads evenly throughout the entire structure. When a storm hits, the loads are directed to the ground via all legs, not only via legs stabilized with bracing.

The pyramid roof is designed much like an umbrella. The 4 legs of the pyramid are folded together, forming one unit during transportation. 

The pyramids unfolds as they are lifted into place.
