May 2009 – RollOuts
Two new crushers debut
McCloskey International launched two new crushers – the C50 jaw crusher and the C44 cone crusher. The C50 (left) is a primary crusher designed with the durability and high performance of a stationary crusher in a portable unit. It features a 350-horsepower Tier III Caterpillar C9 engine, a 50-inch-wide Telsmith jaw, a 42-foot main conveyor, and a level hopper capacity of 8.9 cubic yards (gross hopper capacity is 13.3 cubic yards).
The C44 (right) is a portable cone crusher that features a powerful Caterpillar Tier III 430-horsepower engine, a high-efficiency diesel hydraulic system, heavy-duty hardox steel hopper combined with a metal detector and automatic release system to protect the cone, and user-friendly controls. The crusher sets up in 10 minutes and is highly maneuverable on site. Transport height is 11 feet, 2 inches; length is 53 feet, 7 inches.
Wheel loader gets technological enhancements
Komatsu America Corp. says its new WA150-6 wheel loader with hydrostatic transmission boasts significant technological enhancements over the Dash 5 model to deliver greater performance, operator comfort, and efficiency. Its operating weight is 17,271 to 17,461 pounds and heaped bucket capacity is 2.7 to 2.2 cubic yards. The wheel loader has a breakout force of 16,310 pounds and high static tipping. Features include long lift arms for high dump clearance and maximum dump reach; Komtrax technology, which sends machine-operating information such as fuel consumption, operating hours, working hours, location, and maintenance alerts to a secure Web site via wireless technology; and Komatsu’s exclusive Equipment Management Monitoring System, which monitors all critical systems.
Motor grader with choices
John Deere says its six new G-Series motor graders offer users a choice of console-mounted controls or armrest-mounted fingertip controls, as well as features like cross-slope control, automatic differential lock, and a rearview camera. The graders are available with a front- or mid-mount scarifier, or a rear ripper/scarifier, so users can pick the tool configuration that’s best for the jobs they do. All machines have keyless start with multiple security codes. Three models have six-wheel drive rather than tandem drive, giving operators increased traction and a 30-percent increase in tractive effort.
Hydraulic screen vibrator
Martin Engineering says its hydraulic screen vibrator provides efficient power to sort or separate material and offers improved pricing, delivery from stock, and a three-year warranty. The units work in portable screen applications where no electricity is available and provide up to 8,300 pounds of centrifugal force for material separation. Other features include simple installation, quiet operation, and low maintenance – the company says the only service required is bearing lubrication every 2,000 operating hours.
Self-cleaning conveyor pulley
Douglas Manufacturing says its vortex spiral clean pulley uses an innovative concept in self-cleaning pulley design. The pulley’s spiral design aids in belt tracking by moving the belt gently from the center of the pulley to the opposing edges with equal force. The company says the pulley features a more efficient self-cleaning ability, smoother running with reduced vibration for improved sealing at transfer points and reduced level of noise, a continuous flight design that prevents wing folding, and an abrasion-resistant contact bar that extends pulley life by as much as 50 percent.
Self-service ticketing kiosks
Libra Systems Corp. says its new self-service kiosks act as extensions of the Generation3 system and allow material suppliers to increase revenue by handling more truck traffic without increasing the number of operators. Kiosks are available to handle all of the various roles in ticketing, including check-in, check-in with tare, checkout, and ticket printing.
Backup cameras
RMT Equipment’s new North American line of safety backup cameras, Track-Vision, helps to prevent accidents while maneuvering trucks and equipment. A standard installation includes one heavy-duty camera mounted on the back of a vehicle and a 7-inch color, flat screen LCD installed in the cab. Additional cameras can be added to increase visibility around the vehicle.
