50 • ROCKproducts • December 2018 EQUIPMENT & TECHNOLOGY LOADING & HAULING Off-highway trucks are designed to haul ton-after-ton of material throughout quarries, mines and traverse unpaved haul roads in the pursuit of building economies and infrastructure around the world. From time-to-time, the truck bodies on these trucks cannot contain the material they need to maximize efficiency. Whether the off-highway truck has a tailgate or not, the addition of PHIL Sideboards is useful in increasing the volumetric capacity of the truck body, and it assists in minimizing material spillage over the body sides. Philippi-Hagenbuch (PHIL) Side- boards are available in 1-in. increments from 9 in. to more than 40 in. for most makes and models of articulated haul- ers and rigid frame trucks To compete in a highly competitive rental market, a Caterpillar dealer recently came to PHIL to increase the volumetric capacity of their Cat 745 articulated dump truck by adding 9-in. sideboards. Installation was done at the PHIL factory, but can also be done at the dealership or at the client site. When paired with a tailgate, this set of sideboards increased the volumetric capacity of the truck by approximately 9 cu. yd. – almost 28 percent more room to haul whatever needs to be hauled by their rental client. PHIL, PHIL Sideboards Help Maximize Volume, Minimize Spillage Caterpillar introduced the 990K Aggregate Handler, designed to handle greater payloads in aggregates yard applications. With as much as a 25 per- cent payload increase, as compared to the standard 990K, the new Aggregate Handler enables customers to load trucks and railcars faster and to move more material in load-and-carry and stockpile management tasks. The Cat 990K Aggregate Handler has a payload of 22 tons (20 tonnes) and a full-turn static tipping load of 96,426 lb. (43 738 kg). Additional counter- weight maintains machine stability, and robust 990K structures ensure durability in the Aggregate Handler configuration. The loader makes best use of general purpose and coal buck- ets for increased volume. The 990K Aggregate Handler is avail- able in standard lift configuration with 13.5-ft. (4,108-mm) dump clearance and in high lift configuration with 15-ft. (4569-mm) dump clearance. Increased capacity and high dump clearance enable customers to load railcars and large trucks with a better pass match for faster material handling at lower cost per ton. The 990K Aggregate Handler com- plements the smaller 986K and 988K Aggregate Handlers in the Cat large wheel loader line. The Aggregate Handler, however, is not designed for use in quarry face or other shot rock applications. The new 990K Aggregate Handler is built on the proven features of the 990K Wheel Loader. The 990K pow- ertrain provides powerful operation with superior fuel efficiency. The Cat C27 engine delivers a net power of 699 hp (521 kW). Lower engine speed helps drive economical fuel use. Addi- tional fuel savings accrue with the ECO Mode (on-demand throttle), engine-idle shutdown system, and engine-idle kick- down/auto-resume system. The Cat exclusive, field-proven impeller clutch torque converter uses a lock-up clutch, providing direct drive to boost fuel economy, trim cycle times, and reduce heat – especially in load-and- carry applications. The system allows operators to balance rimpull and hydraulic power for optimum load- ing efficiency. Positive Flow Control implement hydraulics use a variable displacement, electronically controlled pump to precisely apportion oil flow based on operator control inputs. A number of drivetrain options are available. The integrated axle cooling and ride control options are particu- larly beneficial in load-and-carry work. The operator station features the Cat Vital Information Management System, VIMS 3G, which provides customizable operator profiles, a cycle timer and an integral Payload Control System, which provides on-the-go payload weighing. The graphical information display is easy to use and keeps key informa- tion in front of the operator. The Cat Comfort III seat provides integrated seat-mounted controls for smooth and comfortable operation. Transmission controls, integral with the STIC steering lever, allow convenient travel control. The 990K is equipped with the Cat Vision rearview camera system and in-cab display to show the operator the area behind the loader. The optional Cat Detect object detection system builds on the camera system with radars and in-cab software that provide notifica- tion to the operator when an object is detected within the radar cover- age area. The systems are designed to enhance operator awareness, especially in congested loading areas. Caterpillar, Cat 990K Aggregate Handler Boosts Wheel Loader Production
