Atlas Copco takes important step in mechanical rod handling

Atlas Copco launches the rod handling system, RHS E, for use with its Rocket Boomer E-series of face drilling rigs. This means that longer holes for grouting, probing or drainage can be drilled without the necessity of manual rod extension, normally carried out by an operator from the service platform.

In addition to drilling blast holes at the face a Boomer drill rig is often engaged in drilling holes in other directions and for other purposes. In infrastructure projects, especially when excavating through fractured and weak rock or soil, a high number of long holes for pregrouting are drilled 20-25 m ahead the face. This type of drilling requires extension rods. New stricter safety regulations recently introduced in some countries do not permit men standing on the service platform carrying out manual work, while drilling is being performed with other booms. To eliminate time consuming stoppages during extension drilling, one or more booms equipped with RHS E will make the rod handling procedure mechanically while face drilling is being conducted with the other boom(s). The hydraulically driven carousel furnished with two gripping arms accommodates eight 10 ft (3.05 m) extension rods.

−One of the design goals has been the possibility to quickly attach and detach RHS E on site. I am very pleased that we have achieved this very important goal, since it gives the user a very flexible system, says Mikael Ramström, Product Line Manager Underground Drilling Equipment.
 
In addition to an improved working environment RHS E will no doubt make its vital contribution towards faster and more efficient tunnelling.
