Surface Drill Rig The T35 E surface drill rig, the latest addition to the PowerROC product family, is an extendable boom ver‐ sion of the T35 drilling rig currently in use. This new, no‐ cabin model provides straighter holes, more safety and comfort for the operator and easy‐access maintenance. The new PowerROC was designed with an aluminum feed system to drill straighter holes. Aluminum is highly resistant to bending, and the prism shape of the feed profile allows two directional sliding surfaces as a stable guide for the rock drill cradle. The T35 E feed system also uses a cylinder with cables that drives the rock drill cradle to provide more consistent ground contact with the drill bit for higher quality holes. Drilling and tram‐ ming controls are located in three separate areas on the machine. This allows operators to safely and efficiently run the T35 E in difficult environments. There is no need for the operator to stand next to the feed, resulting in less dust and noise exposure. Furthermore, a swing arm provides greater safety and comfort. Atlas Copco Construction & Mining, ROTR Tire The new Double Coin REM‐28S radial off‐the‐road (ROTR) tire is ideal for use on loaders, graders and mobile cranes in winter applications.
