SAS Anchor Systems for Tunneling and Mining 


SAS an­chor sys­tems are used in va­rious ways in mi­ning and tun­nel­ling con­struc­tions and ser­ve to op­ti­mi­ze traf­fic rou­tes or mi­ne raw ma­te­ri­als. De­pen­dent on the con­struc­tion sys­tem used, geo­lo­gy of the sur­roun­ding rock and hy­dro­lo­gi­cal con­di­ti­ons un­der­ground, we of­fer a va­rie­ty of an­chor sys­tems to meet spe­ci­fic pro­ject re­qui­re­ments.

SAS an­chor sys­tems are avail­able using thre­ad bars in the gra­des SAS 450/700, SAS 500/550 (with DIBT ap­pro­val), SAS 650/800, SAS 670/800 and as smooth bars, gra­de E 360/690-830. The wi­de ran­ge of steel gra­des en­su­res tech­nic and eco­no­mic op­ti­mi­zed con­struc­tion sys­tems.

SAS an­chor sys­tems such as the SAS ex­pan­si­on shell an­chor or SAS re­sin an­chor sys­tems are eit­her in­di­vi­dual­ly as­sem­bled or sup­p­lied as pre­as­sem­bled an­chor sys­tems. SAS an­chor sys­tems ef­fec­tive­ly im­pro­ve the sta­bi­li­ty of un­der­ground rock mas­ses. The in­crea­sed load-be­a­ring ca­pa­ci­ty of the rock con­di­ti­ons enables an ear­ly con­struc­tion start, thus pro­vi­ding both tech­ni­cal and eco­no­mic ad­van­ta­ges.

Thanks to our sys­tem­s’ fle­xi­ble ap­p­li­ca­ti­on op­ti­ons, our cust­o­m­ers can choo­se next to me­cha­ni­cal and che­mi­cal an­chors and bolts from a va­rie­ty of an­cho­ring sys­tems, e.g. eye­bolt an­chors, hook an­chors and ad­di­tio­nal roof sup­port struc­tu­res, which are all cust­om-tailo­red to sa­tis­fy in­di­vi­du­al pro­ject re­qui­re­ments.
