Fully Automated Telescoping Stackers

Superior Industries offers an eight-panel, color brochure outlining its TeleStacker Conveyors, a line of fully automated telescoping radial stackers. Units offer customizable automation packages that allow the creation of fully or partially desegregated stockpiles, while meeting more demanding specs and reducing labor and maintenance costs. Stockpiles are built in layers of windrows using an automated system that controls the movements of the stinger, incline and radial travel to complete a desegregated pile according to the limits and increments set by the operator. Models are outfitted with the patented FD series axle assembly, which provides safety and stability during operation and fast conversion from stockpiling to transport mode. Options include the 110-ft., 130-ft., and 150-ft. sizes.

Quantis Reducers with Twin-tapered Bushings

Rockwell Automation offers the Dodge Quantis reducer with twin-tapered bushings. The bushing system option is available on motorized shaft-mount and right-angle helical bevel products. The item was introduced on Dodge Torque-Arm speed reducers. Now as an option on MSM and RHB products, the feature provides easy-on/easy-off mounting for all reducer sizes from factional to 150 hp. A tapered bore in both sides of the reducer’s output hub fits snugly against a matching taper on the outer surface of the bushing, giving the feature its name. Twin-tapered bushings provide reliable support on both sides of the reducer and deliver maximum torque and shock load capability, while eliminating driven shaft damage and reducing wobble, according to the company. The bushing system also fits undersized shafts.

Rivet-attached, Hinged-plate Fastener

R5 MegAlloy rivet-attached, hinged-plate conveyor belt fasteners from Flexible Steel Lacing Company are made of a special metal that offers superior resistance to wear and abrasion, for heavy-duty applications requiring small-diameter pulleys such as those found on portable conveyors, trenchers, cold planers and construction equipment. According to the company, the new fasteners provide two to three times more wear life than conventional steel fasteners. Fasteners are recommended on belts with thicknesses ranging from 7/32 in. to 7/16 in. and with mechanical fasteners ratings up to 450 P.I.W. Fasteners operate smoothly around end pulleys with diameters as small as 9 in. for belts operating at 100 percent of their tension ratings, according to the company.

Air-Supported Conveyor Brochure

A six-page brochure discussing the advantages of the Stealth Air-Supported Belt Conveyor in the transportation of bulk solids is available from Martin Engineering. Stealth units use air pressure passing through openings in the belt support trough to eliminate the need for conventional idlers, says the company. Applied to the belt’s bottom surface, this film of air supplies almost frictionless support for the moving and loaded belt. According to the company, advantages of the design include reductions in friction, which results in reduced energy expense and increased belt life, and the need for only a single, low-horsepower fan to support the belt on a conveyor up to 600-ft. in length. Stealth conveyors incorporate a patented system that allows for retrofitting of existing conventional (troughing idler) conveyors. A modular design provides effective and economical upgrades of even portions of existing conveyors, according to the company.

Svedala Mobile Plant Bulletin

Svedala Industries’ Mobile Solutions—North America bulletin describes the product line for mobile plants used in the construction, mineral processing and recycling industries. According to Svedala, its challenge is to create mobile plants that combine mobility and flexibility with productivity of high quality product. The bulletin shows the range of mobile crushing plants available from Svedala.

Wearwolf Wear Parts

The Frog Switch & Manufacturing Company launched its “WearWolf” brand wear parts after a year-and-a-half of field testing at mining and aggregate locations across the country. Results to date indicate a 40 percent average improvement in wear life over standard manganese castings, according to the company. The company describes WearWolf as “a new generation micro-alloyed manganese steel exhibiting an accelerated work hardening characteristic.” Given the patent-pending status of the new material, no details on the actual manufacturing process can be released, said the company.
“We are so excited about this new product. The industry was ready for it,” said Bill Walters, director of sales and marketing at Frog Switch.The company plans to market WearWolf castings as a premium alternative to less expensive parts produced by low cost, foreign competitors.

Lippmann-Milwaukee 3650 Jaw crusher

Lippmann-Milwaukee, Inc. offers the model 3650 Jaw Crusher for maximum capacity aggregate processing. The machine has been successfully operating in underground applications, such as Conco Western’s North Aurora, Ill., operation, which produces more than 1 million tons of limestone per year. The Lippmann unit has increased capacity 20 to 25 percent, according to Delmar Hansen, the mine’s general superintendent. The jaw uses a unique chamber design, a larger eccentric throw and a toggle plate set at an optimum angle for crushing action resulting in higher crushing capacity, according to Lippmann. The crusher’s oil lubrication system pre-lubes the bearings prior to starting. Oil is filtered as it is pumped through the system and a large tank provides a cooling and supply reservoir. Gauges confirm flow and temperature.

Greystone Aggre-spec III Program

Greystone, Inc.’s Windows-based Aggre-Spec III controls system is designed to allow operators to consistently maintain production of specification sand products. Designed for multi-tasking with other Windows programs for data logging, trending and reporting, its recording techniques monitor feed material-to-spec product ratio. The program detects potential stockpile problems. Management can also observe trends with accurate production records, says the company. The program’s two-method system automatically selects the best process for re-blending sand. Production increases by up to 15 percent can be achieved over programs using single-method systems, according to Greystone. Operators can produce up to two spec products at a time.

Rammer 20 Series Hammers

Rammer 20 Series hammers are designed to provide maximum breaking power at all blows regardless of engine speed, according to the company. The Rammer Constant Blow Energy design is used on six basic 20 series models with ratings from the 200 to 1,600-ft. lb. impact energy classes. Designed for use on smaller carriers such as mini-excavators, skid steer and backhoe loaders, the 20 Series models have working weights ranging from 290 lbs. to 1,810 lbs.

Volvo 7-cu. yd. wheel loader

Volvo Construction Equipment has launched its first model in its new E-Series, the L220E, a 7 cu. yd. wheel loader. Items include a Volvo D12C engine, Contronic 3.0 electronic monitoring and hydraulic pump capacity, improved steering with accumulators, improved serviceability and a new design, according to the company. The turbo-charged, electronically controlled diesel engine produces 92 percent of maximum torque at 800 rpm and maximum torque of 1,301 ft. lbs. at 1,200 rpm.

To reduce sound levels and vibration, the engine is three-point mounted in the rear frame. The unit is also equipped with a new load-sensing hydraulic system that produces constant oil pressure and variable oil flow. A unique and patented Volvo Torque Parallel (TP) linkage lift arm system offers excellent parallel action throughout the entire lifting range, according to Volvo. Other items include Volvo’s APS II (Automatic Power Shift) automatic shifting system; a 6-in. longer wheelbase; and the Volvo Contronic 3.0 integrated electronic engine monitoring system.
