Designed with safety in mind
This cable bolter is designed for safety, with the bolting process performed by a single operator situated away from the drilling, grouting and cable installing module. There is no manual cement bag handling, the ergonomic cabin has better visibility and most safety checks can be done from ground level.
One hole automation and automatic cement mixing process ensure high bolting quality. Drilling accuracy is improved through better process control and automation. There are several automatic functions available, depending on automation level.
The fully instrumented boom ensures fast and accurate boom positioning while RD414 high-frequency rock drill and the drilling control system provide increased penetration rates.
