40-ton articulated truck enters the market
Terex says its new TA400 articulated truck offers a combination of high torque, high horsepower, high capacity, and the highest top speed in the class, making it a leader in productivity.
Standard features include a Tier 3-compliant, fuel-efficient, 450-horsepower diesel engine; maximum rim-pull and gradeability for negotiating inclines; and a large body capacity with low body weight to maximize load size and retention. The truck is equipped with three axles that are locked in permanent all-wheel drive and oil-cooled, wet disc brakes on all six wheels.
The truck’s computerized systems communicate with each other through a CAN-bus system which helps ensure that the truck is running at peak efficiency. The system allows truck data to be transmitted via satellite to almost any location.
A unique four-bar trailing arm suspension system allows operators to travel faster and more comfortably on difficult terrain. Instruments in the cab are positioned in logical groups to assist with drivability and functionality, providing operators with more comfort and total control.
Maintenance is made easy and simple with an electric opening hood, ground-level access to major components, and wide platforms on both sides of the engine.

Comfort, efficiency, and performance
The new R380LC-9 excavator offers hydraulic technologies and standard features that increase comfort, efficiency, and performance, according to Hyundai Construction Equipment U.S.A., Inc. The unit has an operating weight of 84,220 pounds and comes equipped with a 21-foot, 4-inch boom; 10-foot, 6-inch arm; and 1.89-cubic yard, heavy-duty bucket. Other features include a large operator’s cab with additional sound-proofing insulation for quiet operation and Tier III Cummins engine technology for electronic control with maximum horsepower and torque.
Versatile modular screen
The new Sandvik SC screen is an inclined screen with circular motion. The modular deck design enables the use of various screen media for flexibility of use. The rubber modules can be used in feed and discharge areas and feature a removable mechanism for ease of maintenance. Other features include apertures for water spraying devices, modular dust encapsulation, and an adjustable spring suspension.
Single-toggle jaw crusher
Terex Finlay says its new J-1480 tracked jaw crusher features the company’s Jaques single-toggle jaw crusher with increased throughput capacity. The machine is available with direct drive for fuel efficiency and power, or hydrostatic drive which offers reversible operation. The large 10-cubic meter hopper has hydraulically folding sides and a hydraulic wedge clamp system to provide a safe working environment and fast machine set up. The crusher features a vibrating pan feeder linked to an independently driven prescreen which provides separation of dirt, fines, and difficult materials.
Multi-purpose mobile screen
The Powerscreen Warrior 2400 is a multi-purpose unit capable of handling large feed sizes. It features a heavy-duty incline screen with a high-amplitude, triple-shaft drive mechanism, enabling screening, scalping, and two- or three-way splitting and stockpiling of aggregates. Set-up time and ease of operation are aided by hydraulic folding tail and side conveyors, two-speed tracks, a slide-out tail conveyor facility, and a load-sensing collection conveyor circuit. The electrical control system allows operators to monitor and diagnose the machine on site via LCD display.
