Astec Industries’ Materials Solutions Group launched a high-frequency portable screen plant in the PTSC2818VM. The plant is equipped with an 8-ft. x 18-ft. top deck and an 8-ft. x 12-ft. bottom deck. It features externally-mounted vibrators at the ends of the tappets for more aggressive screening action. Astec says the screen’s design creates higher g-force and reduces heat load from material to motors compared to single, center-mounted vibrators, allowing for easier maintenance and adjustments. The screen is equipped with hydraulic operating angle adjustment, a fines collection hopper, top- and bottom-deck discharge chutes and an aggregate spreader.

Heavy-duty breakers built to last

Mazio Attachments says the XL Series of hydraulic rock breakers provides reliable performance in demanding environments such as quarries. Designed for carriers ranging from 1 ton to 140 tons of operating weight, the company says Mazio hammers feature a closed case built from 100 percent Hardox steel to protect the body from wear and impact. This, Mazio says, sets the breakers apart. Standard features include anti-blank-fire technology that minimizes wear, an energy-recovery system that reduces the required oil flow and a double-damping system that results in less vibration. Variable-impact speed and power can be manually tuned using an Allen tool, allowing the operator to adjust the breaker for correct productivity.

Crawler excavator series features several updates

Doosan Infracore North America introduced its -7 Series crawler excavators to the U.S. and Canada. The initial launch includes four models, with more excavators to follow in the coming months. The first models are the Doosan DX140LCR-7, DX225LC-7, DX255LC-7 and DX350LC-7. Doosan says its -7 Series delivers fuel efficiency and productivity for operators. Updates include a strengthened work group with reinforced castings and forged steel pivot points to withstand high-impact work. A new Y-shaped seal at the end of the excavator’s arm provides better sealing to the bucket connection for more performance and durability, Doosan says.
