According to company managing director Phillip Boot, the Eliminator series features significant advances in product design and safety – including an optional torque nut where the hexagon end shears off at a pre-determined torque setting, eliminating bolt head damage caused by overtightening.
Other features include a tapered shank to reduce resin back pressure and large mixing vanes that produce a spin diameter of 25mm, easily breaking open both capsule casings and pushing the empty casings to the bottom of the hole. This eliminates encapsulation failures known as “gloving”
Larger shank deformations assist with continuous resin mixing and very high load transfer; a longer, fully rounded thread produces a nut thread strength up to 10 tonnes.
The Eliminator threaded thrust dowel also comes in a high density version with 2.15 specific gravity that causes the dowels to sink in the coal washery, significantly reducing contamination of delivered coal, Boot said.
The Eliminator can be installed as a normal threaded dowel or as a thrust dowel to eliminate projection into the roadway traffic area.
Like all AROA dowels the Eliminator is continuously reinforced and made in one single structural piece with no weak “glue on” threads or enlargements, Boot said.
