SANDVIK DD422I―UNDERGROUND DRILL RIGS
Sandvik DD422i is an intelligent development drill providing a high level of performance for underground mine development and small scale tunneling, including comprehensive drilling and ground support features. It is equipped with an intelligent torque optimized drilling control system which helps to minimize hole deviation during drilling, reduce jammings, and maximize the tool life and penetration rate.
Sandvik DD422i is available with scalable automation options, from hydraulic boom parallel hold without instrumentation, up to the tele-remotely controlled equipment with drill bit changers and fully automated drilling. Comprehensive drill planning, reporting, and analyzing tools help to achieve high quality results in drilling and blasting precision for maximized pull-out per blast.
MAIN BENEFITS
HIGH LEVEL AUTOMATION
Sandvik DD422i has standard features for automatic drilling and boom movements. Intelligent torque optimized drilling control system helps to minimize hole deviation during drilling, reduce jammings and maximize the tool life consistently.
SCALABLE AUTOMATION
With scalable automation packages, Sandvik DD422i offers a wide range of valuable features for automatic drilling:
• A light and compact teleremote control station enabling the drill to be operated remotely and allowing the operator to drill more holes during shift change, blasting and ventilations times.
• A patented semi-automatic drill bit changer: the bits are changed from a safe location, enhancing productivity and reducing the risk of personnel exposure to hazardous ground conditions.
• The boom collision avoidance system ensures the reliability of automatic boom movements, by automatically re-routing the boom when a possible collision is detected.
OPTIMIZED WORKING ENVIRONMENT
Modern and ergonomic cabin for maximum operator comfort with improved visibility and reduced noise level.
TFX TELESCOPIC FEED (OPTION)
TFX telescopic feeds for multipurpose development drilling with Sandvik DD422i. A versatile feed for face drilling, bolt hole drilling, bolt installation and cross cuttings in a limited space where both long and short rods have to be used.
DUAL CONTROLS (OPTION)
This option allows true multipurpose usage of the drill, improving fleet optimization, versatility and performance. DD422i can be used within multiple and different applications.
DIGITAL DRILLER™
Through simulation, operators develop skills fully from basic boom movements and manual drilling to full automated drilling operations using various training scenarios.
