When you need to meet your drilling and blasting needs at the lowest cost per meter drilled, these powerful and reliable systems make P&H drills your best choice. Our powerful and rugged rotary carriages are able to provide ample torque and bit loading through the toughest rock conditions in the world. Difficult operating environments, such as arctic conditions, high altitude and weak power grids are no match for our drills. Powerful pulldown Top-drive, rack-and-pinion pulldown has fewer wearing components requiring maintenance, contributing to better machine availability Powerful rotary carriages provide ample torque and bit loading to break through the toughest rock conditions Superior propel Mainframes and crawler frames are built for maximum strength and stand up to the most challenging hard rock mine conditions Rugged crawlers and powerful hydrostatic propel drives deliver maneuverability, gradability, and fast set-ups Rugged masts Drill mast is designed for high-cycle fatigue resistance, resulting in less downtime and lower costs for crack repair Mast, constructed of high-strength alloy steel, provides maximum rotary carriage and drill string support Excellent operator visibility and protective operator environment Operator's cab provides a clear, unobstructed view of the drilling area, including the areas surrounding the drill Full windows, coupled with video cameras, ensure that your operator has maximum visibility during drilling and propelling operations Operator's chair can swivel to face the travel direction, allowing safer repositioning FOPS Level II-certified structure and shatter-resistant glass protects your operator during harsh mining conditions Operator controls are located within easy reach to allow for maximum productivity Superior extreme environment capabilities Options are available that make our blasthole drills ideal for some of the toughest mining conditions in the world: Weak power grids: has a soft-start transformer available that reduces the initial inrush current, limiting the impact of starting the drill on weak power grids; this can reduce your overall power infrastructure costs and increase the life of the main motor and compressor (320XPC model) Arctic conditions: equipped with the necessary heaters and insulation to protect both your operator and the drill in temperatures that reach -40°C (-40°F) High altitude: has the power and air capacity to maximize productivity in altitudes up to 4572 m (15,000 ft.) P&H 77XR Robust solid boxer style mast construction with a simple rack and pinion pulldown design to reduce maintenance effort while increasing drilling forces Innovative automatic bit handling and pipe handling functions to improve safety and increase machine utilization P&H 320XPC Up to 68,038 kg (150,000 lbs.) of bit loading Handles 270 to 444 mm (10 5/8 to 17 ½ in.) hole diameters P&H 285XPC Up to 53,524 kg (118,000 lbs.) of bit loading Handles 229 to 349 mm (9 to 13 ¾ in.) hole diameters P&H 250XPC Up to 40,823 kg (90,000 lbs.) of bit loading Handles 200 to 311 mm (7 7/8 to 12 ¼ in.) hole diameters KOMATSU GLOBAL >> Other products and services Construction equipment Forestry log stackers Forest machines Montabert breakers Service Customer service portal Parts manuals portal Product training Regulatory certificates Suppliers SNC portal Supplier portal Conflict minerals Employees Connect using VPN Connect using Citrix My Joy Global Company Global locations Joy stickers Finance Resource library Suppliers Our privacy policy Terms and conditions Website content change request Site map © 2019 Komatsu Mining Corp
