Operating conditions at the Otterbein quarry are made even more difficult when slippery surfaces form in the quarry after rainfall. Pfohl is able to improve the stability of the rig effectively using the optional extendible solid prop on the chassis. In addition, the superstructure can be tilted hydraulically against the crawler frame in the direction of travel to ensure displacement of the center of gravity for optimum stability. \u201cAs well as in drilling, I utilize this option in resetting the rig, when I can align the superstructure against the vertical on the steep slopes,\u201d the quarry manager explains. This greatly assists the driving safety and mobility of the Ranger DX800. Despite the solid construction of the most important components, with a total weight of just 16 t the rig is easy to transport and easy to shunt on the crawler chassis. The comprehensive concept goes into details here. The standard safety equipment of the Ranger DX800 also contains a newly developed protective cage on the mount (Figure 2), with which Sandvik closes the gap in possible sources of danger on the moving parts. Unintended intervention in the circulating operating process can thus be reliably prevented.<\/p>\n The procurement of a drill rig is an investment for at least 10 years \u2013 equipment should preferably last twice as long. \u201cThe Ranger DX800 makes a convincing case there too,\u201d says Pfohl. \u201cSandvik supplies everything from a single source, so long-term maintenance from a single source can also be relied upon. With one welcome exception: Warranty and servicing of the cat motor are dealt with by the local Zeppelin dealer, which also looks after our cat equipment.\u201d<\/p>\n Further information:<\/p>\n![\"\"](\"https:\/\/2025.mining-report.de\/english\/wp-content\/uploads\/sites\/3\/2018\/10\/FN_02_Sandvik_Otterbein.jpg\")
