Built to Last
Built to last. Historic. Linked by generations of employees.

These adjectives all describe Tilcon New York Inc.'s largest operation, Clinton Point Quarry, which has been at its current location for more than 100 years and still has 200 years of reserves left. Situated on approximately 1,200 acres near Poughkeepsie, N.Y., the facility produces an average of 5 million tons of dolomitic limestone per year, which is used for road and building construction. Clinton Point is a 24-hour operation with 120 hourly and eight salaried employees. Read More.

Environmental Recognition
Industries are increasingly committed to environmental initiatives that reduce energy consumption, increase profits or simply maintain positive community relations. This, of course, is nothing new to the aggregates industry, which has practiced sustainable development since long before the notion of "Going Green" was a household trend.

Now that public scrutiny is at an all-time high, it is more critical than ever for aggregate operations to illustrate that they are and have been "green" for a long time. To help spread this message, Rock Products is encouraging operations that excel in environmental stewardship to step forward and share their knowledge and experience. So if you think your operation can help set an example for the industry, tell us about it by e-mailing our associate editor at adam.madison@penton.com

Those with proven programs will be considered for the Rock Products Environmental Recognition Award. There also is potential for editorial coverage, which will help other operations share the success of sustainability as the industry embarks on a new ERA of business. www.rockproducts.com

Backhoe
Allmand Bros.' TLB-6235 compact tractor backhoe handles small to medium earthmoving tasks. The design features oversized pins with composite bearings and urethane lip seals in all working joints to reduce friction and extend service intervals by eliminating metal-to-metal contact, retaining grease and keeping out debris.

The four-wheel-drive system is operated through a hydrostatic transmission. The TLB-6235 houses a 65-hp, servo-controlled hydrostatic transmission that provides positive neutral and infinite control.

The machine also features 6,000-pound bucket digging force; a 9-foot, 10-inch digging depth; dual-cylinder, 180-degree hydraulic cushioned swing that allows precise work in tight areas; and extended-reach loader. Load-sensing steering system requires hydraulic flow only when the operator turns the steering wheel. High-capacity oil cooler extends the life of hydraulic components.

Machine Monitoring
Hitachi has introduced two ZXLink machine-monitoring systems to control its fleet operations. The option levels Advanced and Ultimate add sophisticated capabilities. These operating levels are available for field or factory installation on any Zaxis Dash-3 excavator. The original ZXLink Standard level automatically collects, transmits and manages machine data. The data can be viewed at a single secure Web site regardless of make or model, or which dealer sold the system. Customers can then use the data to check machine operation times, track machine locations, and set restrictions on when machines are allowed to run. The Standard level works on any construction machine with a 12-volt or 24-volt charging system, regardless of make.

The ZXLink Advanced provides all the Standard level features plus a percentage breakdown of machine idling versus working hours. To immediately inform maintenance managers of impending machine problems, Advanced also provides dashboard alerts such as low-fuel warnings via Internet, cell phone or pager.

ZXLink Ultimate provides detailed information needed to extend the economic life of equipment. Machine pressures, temperatures and speeds are captured and displayed or can be downloaded onto a spreadsheet for further analysis.

Advanced and Ultimate levels can be used on all Zaxis Dash-3 excavator models ZX160LC-3 and higher. ZXLink Ultimate systems come standard on the Zaxis 450, 650 and 850 Dash-3 models, with three years of service included in the price of the machine.

Portable Crusher
The Fintec 1107 track-mounted primary jaw crusher is built for tough quarry duty, yet is fully transportable on a low-boy trailer, making it ideal for producers with multiple aggregate sites. Track-mounted plants are becoming more popular in aggregate applications because their mobility allows the crushing and screening system to follow the quarry face, reducing trucking costs.

The Fintec 1107 features a heavy-duty 44- x 28-foot Sandvik jaw crusher. This unit joins the Fintec equipment line including the Fintec 1080 cone crusher, and the Fintec 542, Fintec 570 and Fintec 640 track-mounted screening plants. The Fintec 1107 utilizes a Sandvik single-toggle, hydraulic wedge-adjust jaw crusher with a symmetrical crushing chamber provided by an equal nominal and effective feed opening. A deflector plate at the top of the moving jaw allows all of the effective feed opening to be active, crushing the material from the very top of the chamber. An optimized nip angle ensures that material progresses smoothly down the crushing chamber for high reduction, productivity and even utilization of the jaw plates.

Demand for Mining Equipment to Grow
Global demand for specialized mining machinery and equipment (including separately sold parts) is projected to increase 5.9% per year through 2011 to $33.6 billion. These and other trends are presented in “World Mining Equipment,” a study released by The Freedonia Group Inc., a Cleveland-based industry research firm.

According to the report, advances will be fueled by continued demand for commodities such as iron ore and copper. In addition, the ongoing global thirst for energy will boost global coal output. China and India will be leading sources of mining equipment demand. However, just as important, these nations will continue to fuel demand for mined products throughout the world, thereby providing opportunities for machinery producers. Read More



NIOSH Collecting Data
The National Institute for Occupational Safety and Health is collecting data on the mining industry via a survey, which will be completed during June. “Since 1986, there has been little research on the demographics of the mining labor force, such as age, gender, job title, languages used, educational attainment, race, ethnicity, and years of mining experience,” NIOSH explains. “These data are needed to understand the risk of work-related injuries, disease and fatalities and to customize safety and health interventions for specific groups of the industry. These data also can be used to learn more about the underlying causes of work-related incidents and to identify ways to reduce their occurrence.” Read More
