threadbar® mechanical anchors and mechanical rebar anchors are well established systems with a free length. Anchors with a variable free length enable pre-tensioning and thus an active force transmission. The maximum load-bearing capacity of a mechanical anchor is mainly determined by the stability of the borehole (ground characteristics), the amount of pre-tensioning, and the design of the expansion shell.
Main Advantages
Simple handling and optimized installation time
Immediate load-bearing capacity
Field-proven and reliable anchors
Unproblematic installation in auriferous boreholes
Optimized ratio of anchor force vs. borehole diameter
