Your complete guide to new and updated equipment and supplies in the aggregates industry.

High-Volume Primary Crusher
Telsmith engineered its new PA6060
for high-volume crushing with minimal maintenance requirements. The
primary Andreas-style impact crusher can handle up to 40-inch feed. It
has a solid-type sculptured rotor for higher inertia and greater blow
bar backing support; a hydraulic tilting feed plate that safely
eliminates bridging; interchangeable, reversible mono-block aprons for
wear parts cost control; oversized bearings; and advanced hydraulic
controls that reduce maintenance requirements.
Upgraded 5.75-yard loader
Case Construction Equipment has
introduced the E-series version of its 921 wheel loader, adding a Tier 3
engine, improved operator comfort and visibility, and easier
maintenance. The new engine develops 297 net horsepower in the 921E’s
high-production mode and standard bucket size has been upgraded to 5.75
cubic yards. The machine also has an “economy” work mode to maximize
fuel efficiency in light duty work, and an “auto” work mode in which the
machine’s control system adjusts power curves to move the maximum amount
of material per pound of fuel, according to Case. The machine’s expanded
cab is quieter and visibility has been increased.
Maintenance program for breakers
Atlas Copco Construction Tools has
announced a new three-year service contract and extended warranty for
its hydraulic breakers. ProCare takes the responsibility for periodic
breaker maintenance out of the end-user’s hands and makes the dealer or
service center responsible for it. The agreement includes initial
installation and setup of the breaker, as well as fixed service
intervals based on routine, single-shift breaker use, annual inspections
in the shop, and periodic field inspections.
Improved truck management program
Eaton has expanded its Fleet Resource Manager by adding a new construction package to the Web-based fleet management program to meet the specific mobile resource management requirements of construction and quarry fleets. The new package uses an in-vehicle device to record the movement of vehicles by relaying GPS-based location information via wireless networks of servers. The system also provides two-way text messaging between the vehicle and its home base. It allows fleet managers to generate field service and route compliance reports; the latter measure planned versus actual route and work times.
Hybrid excavator prototype
New Holland used the World of
Concrete show in January to display first diesel/battery-powered
excavator in the North American market. Developed in partnership with
Kobelco, the 7-ton HYBRID prototype is able to use a smaller diesel
engine than a conventional 7-ton excavator; its 2.2-liter diesel works
in tandem with a Lithium Ion battery-powered motor. The motor powers the
hydraulic pumps connected to the boom, arm and bucket cylinders, and
travel motors. The company says the hybrid design cuts fuel consumption
and carbon dioxide emissions by 40 percent.
New excavator series debuts
Case Construction Equipment
unveiled the first four models of its CX B-Series excavators, touting a
20-percent increase in fuel efficiency and 18 percent faster cycle times
for the new machines compared to the models they replace. The company
says it now moves 25 percent more material per gallon of fuel. The new
models include the 120-horsepower CX160B, the 157-horsepower CX210B, the
177-horsepower CX240B, and the 207-horsepower CX290B. All four models
get an increase in horsepower and Tier 3 engines, plus more glass in the
cab for improved visibility and dramatically lower noise levels.
Interior sound is now said to measure a car-like 68.5 dBa.
Super mid-range portable plant
McCloskey International says its
new S130 “high energy” vibratory flat-deck screening system gives
mid-size producers a way to upsize their throughput capacity without
having to invest in a large mobile system. With 130 square feet of
screen cloth across both decks, the
5- by 14-foot screen box of the S130 is said to have 25 percent more screening area than its closest competitors. The unit has a large 10.5-cubic-inch hopper with a “taper out” design to resist bridging.
