Atlas Copco’s new Boltec S rig is designed to prevent the need for manual rock bolt installation on even the smallest of projects. The new rig can be used in tunnels with headroom as low as 2.8m but has a reach of up to 7.5m.
“With this launch, we are filling a gap in the market in terms of small, fully mechanised rock bolting rigs,” says Atlas Copco Underground Rock Excavation division president David Shellhammer. “We’re glad to be able to offer a rock bolting rig that fits the smallest tunnels and mines.
“No one should ever have to work beneath unsupported ground, and with this rig you will be able to eliminate manual bolting which, in many cases, has previously been the only option in this segment,” added Shellhammer.
Another key feature of the new rig is the operator panel, which features only two multifunctional levers that control the whole operation, from drilling to bolting.
Atlas Copco has also incorporated a new resin injection steering system, which is also controlled from the operator panel, and makes the loading of resin cartridges into the pre-drilled hole a lot easier since it is not necessary to move the whole bolting unit. The bolting unit is mounted in a forward facing position. According to Atlas Copco, this makes it easier to install bolts in both the left and right hand corners, and also allows for face bolting when necessary. The bolt carousel can be loaded in a vertical position, resulting in a much faster reload time and a better working environment for the operator.
