Atlas Copco Surface drill rig

CM 785Technical specification

Straight forward design, ground-breaking performance1. Advanced, well proven feed system that optimizes the performance of the rock drill 2. Productive drilling in the most challenging rock conditions due to the high torque and air available 3. Proven and maintenance-friendly hydraulic control system CM 785 is intented for aggregate and cement quarries. The main components are:

Mechanized pipe handling•Automatic throttle•Max engine rpm control•Central hydraulic system test ports•Three speed cooling fan control •Tier III emission compliance•2D electronic angle indicator•Feed extension•Dual pinning for L/R horizontal drilling•Water mist system preplumbed for tank•Preseparator (with swing)•Dust collector•

Retractable dust hood•Thread greasing device •FOPS and ROPS operator safety cab•Cab air-conditioning•Work lights•Back up alarm•Heavy duty tracks with full length rock guards •Track oscillation•Variable air volume control for collaring•DTH hammer lubricator device (pneumatic)•Spindle locking plate and adapter wrench•
