Jaw combines efficiency, versatility, safety
The new C120 jaw crusher from Metso Mining and Construction Technology is said to combine reliability, crushing efficiency, and versatility in both stationary and mobile applications with safety and ease of use. Metso says the crusher’s design is based on finite element analysis and casting simulations, and every detail is engineered for reliable operation and long life. The crusher is said to feature a long, aggressively directed stroke and a fixed jaw die longer than previously seen in a crusher of this size class. Other features include a large 34- x 47-inch feed opening and an aggressive cavity cross section.
Low-cost, high-performance wheel loaders
Volvo says its new L110G and L120G wheel loaders are strong, versatile machines that feature a 25-percent increase in lifting force, a 15-percent increase in breakout force, and up to 5-percent lower fuel consumption in load-and-carry and truck loading duties when compared to their predecessors. The machines feature Tier 4i-certified engines and new driveline systems; heavy-duty axles; variable-displacement, load-bearing axial piston pumps; and advanced electronic monitoring diagnostics.
Small, but powerful impact plant
The new Rockster R700S impact crusher boasts a compact design for easy transport, yet offers powerful performance. The 19.9-ton portable plant is 29 feet, 6 inches long; 7 feet, 10 inches wide; and 9 feet, 10 inches high. It features a hydrostatic drive for infinite crusher speed adjustment, up to 140-ton-per-hour performance, and an inlet opening of 28 by 25 inches. Technical improvements include an enforced rotor and flipped wear plates. Adjustment of the swing beams is effective through an elevating screw.
Flexco says its new PT Smart belt trainer is made of durable materials, is easy to install, and works with both mechanical and vulcanized belts. Featuring pivot-and-tilt technology, the unit is said to apply greater belt-tracking discipline than conventional pivot-only, belt-steering devices. A fully enclosed, stainless-steel pivot bearing downstream from the roller creates an almost immediate tracking result, requires no lubrication, and is guaranteed not to seize, according to the company.
Productive in extreme conditions
Boasting a maximum payload capacity of 27.5 tons, a heaped capacity of 20.3 cubic yards, and a 365-horsepower engine, the new Terex TA250 articulated haul truck is engineered to be productive in extreme working conditions. Features include a high power-to-weight ratio, Tier 3-compliant Cummins engine, a ZF fully automatic transmission with manual override, maximum torque of 1,234 foot-pounds at 1,400 revolutions per minute, and a 104,068-pound operating weight. The company says it is the only truck in its size class equipped with wet disc brakes on all six wheels.
Atlas Copco’s SBU 220 hydraulic breaker features a patented one-piece housing construction — a solid-body concept that integrates the percussion mechanism and guide system into one single block of steel. The one-piece housing is designed to have fewer components to maintain and to provide greater return on investment. The breaker is intended for carriers ranging in size from 6,150 to 13,230 pounds and features an operating weight of 494 pounds and a tool shank diameter of 2.56 inches.
