Designed for drilling hole diameters of approximately 76–102 mm, this hydraulic drifter combines high-energy percussion with powerful hydraulic rotation and efficient flushing. Depending on the rotation motor configuration, the COP1840+ provides rotation speeds of up to 215 rpm and maximum torque of up to 1,970 Nm. The rock drill supports T38E, T45E, and T51E shank adapters, depending on the drilling arrangement, and has an approximate operating weight of 174 kg with the shank adapter.
The 8311 1277 05 complete drifter is supplied by ONSAMAK as a high-quality aftermarket alternative for Epiroc COP1840+ hydraulic rock drilling applications. Designed for compatibility with suitable Epiroc and Atlas Copco surface drilling equipment, the COP1840+ incorporates hydraulic percussion, reversible hydraulic rotation, and effective flushing to maintain stable drilling performance and efficient removal of drill cuttings. One of the key improvements of the COP1840+ design is its enhanced Electrical Control Lubrication (ECL) system, developed to support cleaner operation and reduce wear on the feed and boom components. Its optimized hydraulic damping system helps maintain consistent rock contact while reducing harmful energy recoils and mechanical stress during continuous drilling. Engineered for durability, reliable energy transfer, and extended service life, the complete COP1840+ hydraulic drifter offers a dependable replacement solution for professional surface rock drilling operations.
