This is a self-contained small drill rig for drilling holes and installing rock bolts in low-height stopes. By clamping itself between the footwall and hanging wall the Autorock rig stabilises and guides the rock drill, allowing remote operation and faster penetration. This gives marked improvements in safety and productivity.
The Autorock rig is made in a number of models, to suit different stope widths, user preference of power sources and rock drills.
Today more than 5000 units are operated in South Africa.
The material is hot rolled carbon steel of homogeneous microstructure and uniform hardness across the cross-sectional area. Rock bolt assemblies are packaged as complete, ready-to install units and are used for anchoring, roof stabilisation, rock surface control and structural reinforcement.
Rock bolt assemblies with extended-length coarse thread, for multiple re-tightening after installation with resin capsules. Assemblies comprise the stud, matching nut and bearing plate washer, in a variety of bolt diameters and lengths. Rock bolt assemblies are packaged as complete, ready-to install units.
The stud portion of the Rock Bolt Assembly comprises a deformed steel bar with a cold-rolled thread at one end.
The Tyta Bolt has a 6mm pitch knuckle thread, with proprietary form, from lengths of 200 mm up to a maximum of 500 mm in length.
Its design enables it to achieve 50 % more thrust during drilling or bolt installation compared to other machine types which require a 3rd stage leg for similar reach.
The careful selection of materials and design allows the Super Turbo to be the lightest and strongest machine available which enables it to operate reliably and effectively in even the toughest mining environments.
