A new tramp-release system from L&H Industrial is designed to ensure safety, dependability and ease of installation. L&H says its system removes stored energy by replacing conventional mechanical springs. It also releases pressure on cylinders and allows the adjustment to pick up, repressurizing cylinders to return to the optimal crushing position. The system delivers simplistic design, PLC logic and a large clearing stroke. According to L&H, the system requires minimal maintenance and it can be installed in less than 24 hours. The system can also be retrofitted onto legacy crushing equipment, and it can increase production levels by allowing a crusher to run at maximum feed without fear of a tramp event.

Excavator’s fuel consumption lessened significantly

The new Cat 350 excavator can be equipped with buckets up to 4.2 cu. yd. While productive, Caterpillar says the 350 consumes up to 13 percent less fuel than the Cat 349 to lower costs, reduce carbon emissions and operate more sustainably. Three power mode options – Smart, Power and Eco – match the excavator to the job to further reduce fuel consumption. The excavator features keyless start via a push button, an operator ID passcode or a Bluetooth key fob.

Fragmentation monitoring expands with new tech

Orica launched a fragmentation monitoring technology that combines real-time oversize detection alerts and accurate particle size distribution of fragmentation for all haul truck models and sizes. According to Orica, FRAGTrack Gantry uses advanced machine-vision and machine-learning technologies to enable autonomous triggering and processing – without interfering with hauling operations. FRAGTrack Gantry leverages real-time oversize detection through AI, Orica says. The machine-learning capability is applied to real-time detection that’s accomplished within seconds. Alerts are syndicated via fleet management systems, email or SMS for the rerouting of trucks. Operators can predetermine customizable oversize limits, enabling a reduction in crusher blockage and damage frequency due to oversize material.

Rear-eject bodies available for large hauler

Philippi-Hagenbuch’s rear-eject engineering capabilities now extend to Volvo Construction Equipment’s A60H articulated hauler. According to Philippi-Hagenbuch, the truck features a body volume of 43.9 cu. yd. with a 2-to-1 heap ratio. Each of the rear ejects features an interior width of 156 in. and a loading height of 148 in. They’re built out of strong, abrasion-resistant Hardox 450 steel, the company adds. With rear-eject bodies, Philippi-Hagenbuch says operators can effectively and safely discharge material without having to stop and raise the truck bed, even when the truck is out of position, driving up a hill or under overhead barriers with low clearance. Operators control the ejector blade to push material out of the body while the tailgate mechanically lowers. Rear ejects effectively dump even the stickiest material, further improving hauling efficiency by reducing carryback.

Excavators designed for tough environments like quarries

John Deere added three new P-tier excavator models to its line of large-size equipment. The 470 P-tier, 670 P-tier and 870 P-tier are the latest excavator models to launch as part of the John Deere Performance tiering strategy. The three models feature standard right, rear and left camera systems with added LED surround lighting to provide operators with a 270-degree view of the area around the machine. Auto-idle technology on all three models reduces engine speed when hydraulics are not in use. In addition, auto shutdown further preserves fuel. The P-tier excavators feature three productivity modes. High-productivity mode delivers more power and a faster hydraulic response; power mode provides smooth and balanced metering; and economy mode helps reduce engine rpm. Says John Deere’s Justin Steger: “Our largest P-tier excavators are built to deliver exceptional performance in harsh environments like aggregates [and] help operators increase efficiency and accuracy during high-production applications.”

Digital option gives operators greater plant control

Kleemann’s Spective Connect option, which moves a crusher’s user interface into the mobile equipment housing operators, is now available with a configuration tool. According to Kleemann, Spective Connect’s smart job configurator helps in the selection of the correct machine settings. To start, operators enter the data of their planned application into the Spective Connect app, which calculates the optimum machine settings automatically. Operators can then transfer the settings to the machine via the Spective touchpanel. Kleemann says the new tool supports operators in the selection of the best possible crushing tools. Additionally, the company says all installed optional belt scales can now be displayed in Spective Connect.

Keep belts clean with uniquely designed component

The U-Scrape secondary belt cleaner’s unique “U”-shaped design conforms to the return side of the belt while the blade maintains maximum pressure in the center where the majority of the carryback material builds up. The U-Scrape’s “U”-shaped urethane and tungsten carbide blade tips are in constant blade-to-belt contact for the highest cleaning efficiency, ASGCO says – especially in tough applications requiring the removal of water and sticky carryback materials.
