Look to the DM series of drills for the best value in quality, productivity and reliability to achieve your blasthole drilling objectives.
• The robust DM45/50 mainframe and tower design ensure a high asset life even in some of the toughest mining conditions. The double cut structural tower lacing ensures a strong tower structure without the added weight of less efficient designs.
• A spacious one piece FOPS (Falling Object Protective Structure) rated cab with electric over hydraulic controls that are common with the DM30 II and DML make the DM45/50 easy to operate, especially for drillers who have experience in other DM series machines.
• For single pass applications the DM45/50 can achieve a clean hole depth of 8.5 m (27.4 ft) and for multi pass depth can achieve depths of up to 53.3 m (175 ft).
• When more air and pulldown are required, the DM45 evolves into a DM50 to give added flexibility to the larger hole sizes in the DM45/50 range.
