Certified tech a replacement for traditional scales

Walz Scale achieved government legal-for-trade certification for its Walz Scanner volumetric measurement technology. The NTEP (National Type Evaluation Program) certification is the first of its kind in the U.S., Walz Scale says, and verifies the technology as an accurate volumetric bulk measurement system. According to the company, the Walz Scanner utilizes laser technology to scan and measure bulk material loads in trucks and railcars. The system operates like truck and rail scales yet allows operations to achieve legal-for-trade volumetric load measurements while a vehicle is in motion. The certification means operations can utilize the Walz Scanner as a replacement to scales to improve business processes.

Excavator offers reliability in quarry environment

Caterpillar unveiled a new hydraulic excavator that it sees as a fit for aggregate applications. According to Cat, the new 352 combines more power and a heavier counterweight to work with larger tools. The result is greater production for more profit potential, Caterpillar says. The 352 offers a choice of fixed- or variable-gauge undercarriage. The variable-gauge undercarriage retracts to a 7-ft., 10-in. width, making it easier to transport. When expanded, it is 6 in. wider than the fixed-gauge undercarriage for greater stability. Different cab trim level options are also available. Cat says the deluxe cab option comes with a heated air-suspension seat. The premium cab option comes with a heated and ventilated air-suspension seat. Both have a tilt-up left-hand console for easier access in and out of the machine.
