Rollouts August 2011
The Doosan DL200TC tool carrier with parallel-lift linkage system keeps the work tool flat as it is lifted, an advantage when loads need to stay level. Built around a Tier 3-compliant, 143-horsepower, six-cylinder Doosan diesel engine, the machine has an operating weight of 25,708 pounds with a standard 2.6-cubic-yard bucket; dump height is 8 feet, 11 inches; and dump reach is 3 feet, 1 inch. Bucket breakout force is 23,149 pounds with a pin-on bucket. Static tipping load is 18,913 pounds with a straight frame and 16,272 pounds at the maximum steering angle of 40 degrees. Four forward speeds range from 4.1 to 21.7 miles per hour; three reverse speeds range from 4.5 to 15.5 miles per hour.
Titan Tire Corp. says its next generation 007 MFT mining tire offers enhanced durability, a more aggressive tread pattern, and improved heat dissipation. According to the company, testing shows that the nylon casing design ran 15-percent cooler than the steel casing in an equivalent tire, which makes the tire less susceptible to sidewall fatigue and cut damage. A new triple-bead belt package is said to improve durability, as well as the cut, chip, and wear characteristics of the tire. Sipes are incorporated into the tire lugs to provide additional traction and heat dissipation. A non-solid, center-tread design helps reduce internal heat generation and allows the heat to more easily dissipate, which allows end users to run haul trucks longer distances and at higher speeds. The tires are available in 59/80R63, 53/80R63, 40.00R57, and 27.00R49 sizes.
Major Wire says its new line of 1- by 2-foot Flex-Mat 3 self-cleaning, polyurethane modular screen media panels will fit virtually any flat-surface screen deck, allowing screening operations using traditional polyurethane and rubber panels to increase their screening capacity and in-spec material throughput up to 50 percent. Operations can choose between snap, step, pin, and grooved panels with opening sizes of 0.020 inches up to 1½ inches. Each new 1- by 2-foot panel increases total screen media open area by 4.6 percent when compared to two 1- by 1-foot panels. No screen box changes are necessary to switch to the larger panels.
Diesel-powered portable stacker
McCloskey International’s new diesel-powered, track-mounted stacking conveyors can be easily moved and reconfigured on site as operational requirements change. The Track Stackers are 36 inches wide and are available in 65-, 80-, and 100-foot lengths. The 80-foot model has a maximum capacity of 500 tons per hour at the highest incline; the 65- and 100-foot models can carry 600 tons per hour. Up to 800 tons per hour is available as an option on all three models. The company says the conveyors are counter-weighted and the undercarriage is set back from center, which allows them to run at a 22.5-degree incline and stockpile all the way to the head pulley without burying the tracks. Discharge heights are 25 feet, 10 inches for the 65-foot stacker; 36 feet for the 80-foot stacker; and 40 feet, 5 inches for the 100-foot stacker.
Mettler Toledo says its new VTS101 and VTC101 truck scales use a Powercell PDX load cell technology that eliminates the typical maintenance, repair costs, and downtime related to conventional vehicle scales. The VTS101 consists of a steel deck supported by orthotropic ribs that are sealed from the elements by automated continuous welds. The VTC101 draws on the strengths of both a concrete driving surface and a steel orthotropic understructure, thereby eliminating voids in the deck that occur when pouring concrete around I-beam flanges and sharp corners. The company says the Powercell PDX load cell provides predictive diagnostics, including automatic notification of weighing errors, overloading, environmental conditions, network health, load cell voltages, and enclosure integrity, without the need for maintenance-prone external converter boxes.
