Tier 4 final certification

Caterpillar Inc. says its new Tier 4 Final 777G off-highway truck offers next generation transmission control with its Advanced Productivity Electronic Control Strategy (APECS), which provides greater productivity at better fuel rates with torque shift management that allows the truck to carry more momentum up grades. The Tier 4 Final engine requires the use of ultra-low sulfur diesel fuel and low ash engine oil, but requires no additional maintenance or operator input. Additional features include enhanced braking and traction control, hydraulic oil-immersed disc brakes, a traction control system that differentiates between tire spin and high-speed turns, wider cab access with hand rails, 50-percent lower noise levels in the cab, and a combination of radar and cameras for enhanced safety and object detection. Maintenance is convenient with ground-level service centers for both electrical connections and fluid fill.

Decreases cost per ton

Buffalo Wire Works says its new Clean PFX screens are engineered to decrease cost per ton through effective use of available deck screening surface area, greater specification produced per unit time, increased screen life, newly innovated polyurethane strips, and wires that vibrate independently from one another at different frequencies preventing material build up. The screens are said to solve the toughest and most severe screening problems while maintaining materials in spec and reducing blinding and pegging. An extensive range of openings is available, and no modification of the crowned deck is required. The screens are available in several models for different applications — Clean PFX-M Series, Clean PFX-N Series, Clean PFX-L Series, Clean PFX-Harp, and Clean PFX-Clean Slot.

Lightweight, powerful breaker

Atlas Copco Construction Equipment says its new HB 4100 heavy hydraulic breaker has a service weight of only 9,039 pounds (designed for carriers in the 88,185- to 154,324-pound weight class), but is as powerful as much heavier breakers. Improvements to the breaker include a guide system that makes the breaker more stable and resilient, a new cover plate for the retaining bars that offers more protection in the lower part of the breaker, and increased wear protection at the bottom of the case. The breaker is suitable for secondary and primary rock breaking.

Maximizes haul truck capacity

Philippi-Hagenbuch says its line of Autogate Tailgates is designed specifically as an avenue to increase haul capacities by up to 20 percent, while also providing added safety and extended tire life. The line of tailgates includes models suited for both articulated and rigid frame trucks and is said to be effective for any material — hard and rocky or liquid. The company constructs each tailgate to the specific spec of each model.
