CM 765 and CM 785 Hydraulic DTH Drill rigs

  CM 765 and CM 785 crawlers reflect the straightforward design of the drill rigs in AtlasCopco's 700 series. The rigs combine well-tested features and components common to AtlasCopco's ROC crawler range.

 

 

 

 

Combining productivity and cost efficiency

    Modifications have been made to further improve drilling capacity, hole quality, and overall cost efficiency. The CM 765 and CM 

785 DTH crawlers maximize productivity by drilling high-quality holes at a high penetration rate with optimum fuel economy, long accessory life and low maintenance costs. The CM 765 and CM 785 DTH crawlers are built for maximum profitability.

Advantages of the CM 765 and CM 785:

A highly-advanced, dependable feed system optimizes rock drilling performance.

Productive drilling, even in the most challenging rock conditions.

A reliable, maintenance-friendly hydraulic control system.

 

The powerful rotary head provides sufficient torque, even in the toughest rock conditions. This reduces the risk of jamming, leading to high productivity.

 

Tube breaking directly by the rotary head with the help of low-torque Z threads reduces wear on the pipes since there is no mechanical hard grip when breaking the joints.

 

A cylinder-driven,aluminium feed system.

 

Variable cooling fans optimize horse power draw and minimize fuel consumption and ambient noise.

 

An adjustable air flow switch allows the operator to adjust the flushing air volume as required from the cabin to improve hole quality, especially when collaring in poor rock conditions.

 

Spacious, operator cabin certified by FOPS and ROPS. Load sense-activated engine RPM control (auto throttle)helps save energy and reduce noise.

 

Optimal power for maximum profitability

The CM 765 and CM 785 DTH crawlers are equipped with a cylinder driven aluminium feed system that provides smooth feeding and contributes to a high penetration rate and long accessory life. The system secures  continuous  contact  between  the  drill  bit  and  fresh  rock to optimize the performance of the rock drill. The rigs are also equipped with an adjustable air flow switch that enables the operator to regulate the  flushing  air  volume  as  required  from  within  the  cabin  to  help maintain  hole  quality, particularly  when  collaring  in  poor  rock 

conditions.

 

Flexibility and mobility in focus

The CM 765 and CM 785 DTH crawlers have excellent terrain manoeuvrability. The well-balanced and sturdy super-structure with 432mm (17 inches) of ground clearance and full-length rock guards enable  the  rigs  to  drill  in  rough,  highly-demanding  terrain. Sufficient air and high torque allow the rig to cope with a wide range of rock conditions.

 

Ease of maintenance

To  minimize  and  simplify  maintenance, the number of hoses and valves on the feed system has been reduced to a minimum, and the breakout table has been built in a single piece. Simplified electrical system and pilot control hydraulics are easy to maintain. The feed profile  itself  is  sturdy  and  highly  resistant  to  bending,  with  sliding surfaces  protected  by  easily-exchangeable  steel  caps  that  virtually eliminate feed profile wear. The aluminium cradle is designed for easy retightening to compensate for sliding pad wear, ensuring smooth guid-

ing  at  all  times.  Service  points  are  within  easy  reach  along  the perimeter.

 

 

Optimimum fuel economy

Both models are equipped with variable-speed cooling fan controls to optimize horse power draw and fuel economy while minimizing the ambient noise  level.  Load-sensing hydraulics  and  engine  auto-throttle  help  to  save energy and minimize fuel consumption.  

 

Arctic package for extremely cold climates

 

The package consists of a 100,000-Btu, diesel-fired heat exchange pump that preheats the engine, fuel tank, hydraulic oil tank and water mist tank. A pressure-relief valve unloads the compressed air tank to  ensure easy cold start. The air regulators are also covered by heated pads, and all exposed hoses are spe-

cifically designed for arctic climate.
