AGGREGATES MANAGER March 2014 6 Improved sand tank controls Eagle Iron Works' new Mark VI controls are said to improve the accuracy and simplicity of the calibration process and enable quick and easy adjustments. In under a minute, the system can recalibrate products. It also remembers specific product calibrations, allowing it to switch back and forth automatically as the feed changes. The number of products that can be simultaneously produced has increased to five products, and the system can have a different percent retained, percent passing, or cumulative percent retained for each product. It will also predict the tons per hour of each product and the total feed coming to the classifying tank, as well as maintaining daily tonnage accumulators. After it brings a product within specification, the controls make sure the fineness modulus of the product falls within a specified minimum/maximum range. Eagle Iron Works | www.eiwllc.com Telescoping stacker A new 170-foot long SuperStacker, from KPI-JCI and Astec Mo- bile Screens, is the company's latest model of telescoping stackers designed to minimize stockpile segregation and increase stockpile capacity. The new system is an addition to the new gen- eration Super- Stacker prod- uct line, which eliminates the echain, reducing field maintenance. It also features an updated Wizard Touch automation control system. KPI-JCI and Astec Mobile Screens | www.kpijci.com Side dump bucket The JRB side dump bucket, from Paladin Attachments, is designed to give wheel loader operators more flex- ibility than a standard bucket can offer in construction applications. It can dump from many angles, making it ideal for confined or hard-to-maneuver areas. One side of the bucket is shaped like a standard bucket to hold material while the other side has a 45-degree side-shoot dumping angle that allows for full side dumping. The bucket carries up to 4 cubic yards and is available in left- and right-hand dump functions. It features the JRB sequence valve that locks and unlocks the bucket cradle and side dump function to enhance safety and control during transportation and placement. Paladin Attachments | www.paladinattachments.com Upgraded off-highway trucks The new Cat 770G and 772G off-highway trucks were redesigned with major advancements in emission technology, transmission, and traction control systems; frame, drive-train, and cooling system enhancements; added operator amenities; and serviceability improve- ments. Available in Tier 2, Tier 3, and Tier 4 Final configurations, the engines can be programmed to achieve the customer's specific fuel economy goals. Two programmable modes are available, Economy and Adaptive Economy, while a new auto neutral idle feature automatically places the transmission in neutral gear after the brake is applied for more than 15 seconds while in a forward gear. A new transmission control system, Advanced Productivity Electronic Control Strategy (APECS), offers improved shift quality, faster accelera- tion, better speed on grade, and faster cycle times. Also new is a four-post ROPS/FOPS structure that is integral to the cab, and the cab is resiliently mounted to the frame to dampen sound and vibration. Operator safety is enhanced with handrails, lighting, and a low-effort stair step system. Both trucks come standard with VIMS 3G, Cat's Vital Information Management System, Truck Production Management System (TPMS), TMPH (Ton Mile Per Hour) / TKPH (Tonne Kilometer Per Hour) tire management system, and Product Link.
