FLEXCO Controlled-flow transfer chutes Matches breaker frequency to ground conditions The DXB260H hydraulic breaker from Doosan features two-speed control of breaker frequency, which allows the operator to match the breaker frequency to the ground conditions. The 5,400-pound breaker delivers up to 600 blows per minute and is designed for use with excavators in the 27- to 37-metric-ton weight range, specifically Doosan's DX300LC and DX350LC. Standard features include a cradle-mounted grease station that delivers continuous grease flow to reduce bushing and tool wear, and blank-fire protection that uses a cushion of oil at the base of the cylinder to reduce metal-to-metal contact. The breaker's suspension system extends excavator workgroup life by absorbing harm- ful vibrations and stress waves. A patented main-valve design reduces hydraulic pressure peaks that can reduce pump life, crack excavator workgroup welds, and cause system overheating. An energy recovery system increases strike power Flexco uses Tasman Warajay Technology to develop custom transfer chutes for material- handling operations. The controlled-flow technology improves throughput and conveyor belt life, yet reduces excessive dust, spillage, plugging, downtime, belt wear, material degradation, and noise. Each material transfer system is designed to control the flow of material by keeping it in a continuous stream throughout the transfer. Material discharged from the system is deposited softly and uniformly at a predetermined velocity and direction on the receiving belt, so the material settles rapidly and without turbulence.

Hitachi says its Zaxis-5 Series excavator — the ZX210-5 — is loaded with customer-driven enhancements. It features an Isuzu EPA IT4-compliant engine that is easy to maintain and requires no special additional fluids other than ultra-low-sulphur diesel fuel and CJ-4 engine oil. The excavator features hydraulics with multiple sensors that instantly feed automatic micro- adjustments for increased hydraulic power to maintain steady movements. A multi-language LCD monitor in the cab tracks scheduled maintenance and provides diagnostic codes to assist in troubleshooting. The boom, arm, and mainframe are warranted for three years or 10,000 hours, whichever comes first. Filters and checkpoints are conveniently grouped, and centralized lube banks are easy to reach. Optional features include a rear-view camera; a control pattern change valve; a variety of track widths, arm lengths, and bucket sizes; high-flow auxiliary hydraulic JOHN DEERE Operator-friendly artic truck John Deere's 460E articulated haul truck is said to be the largest, most operator friendly truck ever built. The 46-ton truck features a John Deere PowerTech 13.5L IT4 engine with 481 net horsepower. A purpose-built ZF transmission includes a high-capacity retarder, eight forward gears, and four reverse gears. The new axles in- clude on-the-fly differential locks and outboard planetaries. Axles are independently pressure lubed and filtered and use internal wet disc brakes with independent cooling circuits. With the differential lock system in automatic mode, it will automatically control the axle differential locks and the inter-axle differential lock when ground conditions get soft and difficult, all while the truck is moving. The dump body can be restricted from rising when the rear chas- sis exceeds a predetermined slope angle to minimize rollover risk. An onboard weighing system allows operators to view the weight and number of loads carried via JDLink. John Deere; deere.com.
