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.
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.
New concrete plants
Astec Inc.’s new line of concrete products and facilities includes individual components and full plants, as well as a roller-compacted concrete plant. These plants offer continuous blending, belt scales with weigh idlers and fully variable speed drives, in-house designed twin-shaft mixer, and self-erecting cement silo. The stationary concrete facilities combine modular structures with built-in stairs, decks and ladders, and interchangeable deck mixers with the company’s proprietary surge hoppers. Seismic designs are available. Equipment will be sold through the company’s newly formed Concrete Products Group.
Online safety training
Caterpillar’s Web site, Safety.Cat.com, partnered with PureSafety to expand its services to include online safety training. The new safety training Web site, Safety.Cat.com/training, offers classes related to general safety awareness issues common at most job sites. Available courses include Environmental Awareness, Fall Protection, OSHA 10-Hour Training Program for Construction and General Industry, Trenching Safety, Scaffolding, Electrical Safety, and more.
Columbia Steel Casting Co., Inc. specifically designed its new anti-slab jaws to handle troublesome slab materials. The jaws are based on traditional and high-tooth jaw designs, but with additional raised slab breakers in pitch with conventionally located teeth. Jaws are available in standard manganese steel alloy and in Xtralloy premium manganese.
Self-lifter for equipment
Vacuworx International released its new patent-pending, fully self-contained self-lifter, which attaches easily to excavators, forklifts, wheel loaders, cranes, and boom trucks. It lifts materials such as steel plates, concrete slabs, or landscape rocks, as well as tubular products such as steel, concrete, plastic, or coated pipe, according to the company.
Attachment locking mechanism
Caterpillar’s new center-lock pin-grabber coupler for hydraulic excavator models 311 through 385 uses a patented over-center locking mechanism and two hydraulic locking features to assure work-tool attachment. An in-cab switch engages the coupler with a work tool; the coupler’s cylinder extends to close the primary hook around the tool’s rear pin; the cylinder housing adjusts its position and forces a combination of three attached parts – center-lock rocker, connector link, and secondary lock – to snap into an over-center position (similar to closing the handles of locking pliers). This action forces the secondary lock to grip the forward pin. Constant hydraulic force exerted by the cylinder and the action of a counterbalance valve provide additional locking forces.
Innovative wheel wash system
Vehicle & Equipment Washers, Inc. (VEWI) says it uses its patented flushing system to make its wheel wash system the only self-cleaning system in the marketplace. VEWI’s patented solid steel or concrete self-flushing wash deck alleviates the risk of structural failure and debris build up of elevated grating designs. The TW1000 and TW1000 Plus are permanent systems. The TW2000 (shown) is a completely portable system that arrives on the job site as a complete unit including wash unit, filtration tank, pumps, and all hoses and fittings. Assembly takes approximately 2 to 4 hours depending on the desired optional equipment.
Extend life cycle of tools/equipment
La-Man Corp.’s patented series of extractor/dryers is a two-stage filter that removes moisture and contaminants to improve and extend the life cycle of tools and equipment. According to the company, the air filtration system operates most effectively within 25 feet of the point of use. Each model offers a standard 5-micron rating, with lower micron ratings available. Flow ranges vary from 15 to 2,000 scfm and pressure ratings of up to 250 psi. Additional features include a built-in differential pressure gauge and weep drain, and in-line dryer.
Caller ID streamlines dispatch orders
Command Alkon says its new Auto Caller ID (ACI) feature for its CommandSeries line of products streamlines the order entry process for dispatchers. When a call is received, the ACI pops up a display on the dispatcher’s monitor. Features include automatic customer lookup from existing entries, expanded order history information displays, automatic display of New Contacts screen for easy data entry if the caller is a new customer, ability to search for contact by phone number and by name, and easy integration with the VoiceGate call-processing technology.
