New Holland Redesigned 3- and 4-yard Models

New Holland has unveiled Tier 3 upgrades of its W170B and W190B wheel loaders. The 195-horsepower W170B competes in the 3-cubic-yard bucket class, while the 227-horsepower W190B competes in the 4-cubic-yard class. Both units got an increase in engine horsepower, along with redesigned cabs that feature better visibility, more floor space, and a new steering column with standard LCD screen to check pressures and recalibrate the calipers. The machines offer four power modes so that the operator can optimize fuel efficiency based on performance requirements.

High-production impact crusher plant

Terex Finlay says its new I-1312 impact crusher plant features high throughput, large reduction ratios, and fast setup. The multiple-speed impactor is designed for primary and secondary crushing of limestone and asphalt and concrete rubble. It utilizes a high-performance Cedarapids 5048LP impact crusher with a large discharge opening and standard three-bar or optional four-bar configuration. Other standard features include hydrostatic drive, advanced electronic control system, hydraulically assisted apron setting, grizzly feeder with integral pre-screen, selectable discharge to bypass conveyor or main conveyor, and dust suppression on the main conveyor.

Mobile crushing’s new generation

Metso Minerals heralds its new Lokotrack LT1315 and LT1415 as an entirely new generation of mobile primary impact crushing plants. The new models are said to combine constant high crushing capacity (up to 900 metric tons per hour), a broad range of process options, operator friendliness, and dust and noise-reduction options. The units can be transported on a standard trailer and have low transport heights, according to Metso. They can be equipped with a magnetic separator and pan feeder below the crusher for trouble-free processing of recycled material containing rebar. They use Nordberg NP Series impact crushers and can handle medium-hard rock such as limestone as well as rock-based recycled materials.

Bigger, tougher belt cleaner

Richwood says its new 1C-ITC Magnum Belt Cleaner has been engineered to handle extreme bulk-handling conditions on 84- and 96-inch conveyor belts. The new design is said to provide the same cleaning performance on large conveyors as the standard Model 1C provides on lesser belt widths. It uses Richwood’s patented ITC blade media, which incorporates a unitized blade cartridge with three media layers. Its extreme duty tensioning design is said to work in all operating conditions, including highly corrosive and extreme service environments.

High-speed pre-cleaner

ASGCO designed its new Skalper MDX pre-cleaner for high-speed, high-tonnage conveyor systems in above-ground and underground mining. It has heavy-duty urethane blades to withstand abusive conditions. They mount against the head pulley to provide continuous cleaning. The adjustable 6-inch blade segments can be replaced by removing two bolts. ASGCO says the most unique feature on the Skalper MDX is the torque cam action lever. The impact force creates torque that rotates the blade allowing it to self-adjust to the angle of the belt. The company says this is ideal for removing high volumes of carry-back with minimal blade wear. It also prevents the mounting tube from bending because it allows the tube to rotate and to absorb the shock.

Longer-lasting linings

Cleveland-based Tribco is promoting a 100-percent Kevlar fiber composite lining for brake/clutch plates that it claims lasts three to five times longer than other linings. The company’s Braketex and Clutchtex linings are said to be non-abrasive and ideal for truck clutches as well as wet and dry brakes used on crushers, excavators, loaders, and other aggregates industry equipment. The company stocks replacement brake pads and clutch facings, relines plates and pads, and custom fabricates to order.
