Top 25 Rollouts of 2010
Harp wire reduces downtime
Major Wire says its new LFM Harp Wire is manufactured with straight wires firmly molded into polyurethane strips that hold the wires in place at the crown bar, eliminating steel-on-steel wear. The polyurethane strips are said to keep the wires equally tensioned, creating better wire vibration, reducing blinding, and increasing production of a cleaner aggregate. The company says its new wire handles high-impact loads better and lasts up to twice as long as conventional harp and piano wire.
Earthmover tires for rocky terrain
Michelin Earthmover Tires says its new X-Traction tires are now available in North America. The E4 tires are designed for earthmover transport equipment operating in rocky terrain. A new cooling system shoulder design and C2 Technology casing architecture reduce heat build up, allowing trucks to operate continuously at higher speeds. The tires feature 13-percent deeper tread and thicker under-tread rubber for resistance to cuts and impacts.
Low-profile, high-capacity scales
Mettler Toledo says its VTC221 concrete deck scale incorporates the newly released Powercell PDX load cell network. The scale combines a concrete driving surface with an orthotropic understructure found in steel deck scales for extra strength. Features include a low-profile design; 100,000-pound concentrated load capacity; gross load cell capacity of more than 800,000 pounds; onboard diagnostic capabilities; lightning protection; and a 5-year warranty on parts, labor, and travel.
Efficient portable crushing
Powerscreen’s Pegson XA750 portable jaw crusher is fitted with a hydraulically driven pan feeder and live pre-screening unit with a bolt-in, cartridge-style grizzly section to remove fines and sizes prior to crushing. A 55- by 32-foot unrestricted feed opening prevents bridging and maintains consistent feed. Features include a hydraulically adjustable product conveyor with a 13-foot, 1-inch discharge height; a modular hopper that can be removed for transport; and two-speed tracks for maximum site mobility. The product conveyor can be raised and lowered hydraulically during operation and for transport or maintenance.
Weigh on the go
Rice Lake Weighing Systems’ new WLS-C compact on-board weighing system for skid steers, wheel loaders, track loaders, and lift trucks offers a compact profile that fits easily into any cab, at an economical price. The system installs with a printer to create an all-in-one mobile weighing and ticketing operation, thereby reducing unnecessary trips to a central scale.
Land-based bucket-ladder dredge
Rohr Corp.’s newest development in underwater mining technology, its land-based, bucket-ladder dredge, is new in the United States. The company says the dredge can extract deposits at shallow-water depths of 36 to 40 feet. Once extracted, the material can be stockpiled, conveyed directly from the dredge, or fed onto a haul truck.
