Resources
Features and benefits
Powerful pulldown
Built for availability. Positive bit loading with an electric top-drive rack-and-pinion pulldown means a reduction in wearing components. This feature also offers a robust and precise way to transmit the pulldown force into the bit.
Rugged masts
Drill masts must tolerate high loads, so we used finite element analysis to achieve high-cycle fatigue-resistant structures and control downtime and costs due to repairing cracks. Constructed of standard high-strength alloy steel, the mast provides robust rotary carriage and drill string support.
Superior propulsion
Built for durability with mainframes and crawler frames that can stand up to your hard-rock mine conditions. Rugged crawlers and powerful hydrostatic propel drives deliver maneuverability, gradeability and fast set-ups.
Ample, reliable air compressors
A range of dependable, mining-duty compressors are available to meet the specific bailing air needs for your mine operations. The 320XPC's compressors provide quality service.
Superior operator visibility
Operators have a wide view of drilling and surrounding areas with windows and video technology to help them maintain situational awareness while drilling and propelling. The operator's chair swivels to face the direction of travel during propelling for ease of repositioning.
Productive operator environment
Operator comfort and productivity are key in the FOPS Level II-certified structure, which features shatter-resistant glass, ergonomic controls, intuitive displays and an adjustable air seat suspension with viscous cab mounts to mitigate harsh vibrations.
Easy-access deck design
Safety and serviceability are a priority, with an efficient deck layout that provides wide exterior and interior walkways. Operators have ample room to quickly and easily change bits and pipes with a large rear deck.
Advanced diagnostics
Enhance your machine’s performance and reliability with advanced diagnostics. The Centurion electrical control system uses intelligent sensors and input/output devices that precisely monitor and control hundreds of points on the drill.
PreVail RHM
Support your drill’s productivity with timely and efficient machine health and performance data. The PreVail RHM system transforms data into actionable insights.
Built to withstand arctic conditions
Protect your operator and equipment from low temperatures. The 320XPC is equipped with harsh-climate systems and features to perform in some of the coldest environments.
High-altitude performance
Committed to providing consistent drilling equipment wherever your mine is located, the P&H 320XPC was designed with the power and air capacity to promote productivity at altitudes over 14,000 ft (4,250 m).
Weak power grid protection
An optional soft start transformer mitigates starts on weak power grids by reducing the initial inrush current by over 75 percent compared to regular application without the soft start transformer. This feature may help control your power infrastructure costs and can promote extended main motor and compressor longevity.
