MinePro distributes P&H crawler and walking draglines with bucket capacities ranging from 10 to 160 yd3/13 to 122m3. P&H draglines handle some of the world's most demanding material moving challenges and perform at unprecedented levels of efficiency, reliability and availability. With boom lengths from 290 to 405 feet/88.4 to 123 meters and a highly reliable four-chord boom design, the flagship P&H 9020 delivers giant productivity gains. Using computer analysis, P&H engineers have optimized the geometry of the P&H 9000 Series machine's A-frame, mast, and boom combination for maximum efficiency, structural integrity, and dynamic performance. The P&H 9000 Series large-diameter roller circle provides more rollers to distribute loads on the rail-pad support structure and reduce contact stresses, greatly improving reliability in the tub and deck as well as improving roller circle life. Both the walk and swing systems feature quality P&H designed and built planetaries for smooth and dependable operation.
