SUPPLY CHAIN NEWS – LOAD & HAUL

Cat 990K Aggregate Handler boosts wheel loader production Caterpillar has introduced the 990K Aggregate Handler, designed to handle greater payloads in aggregates yard applications. With as much as a 25% payload increase, as compared to the standard 990K wheel loader, the new Aggregate Handler enables customers to load trucks and railcars faster and to move more material in load-and-carry and stockpile handling tasks. The Cat 990K Aggregate Handler 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 power- train provides powerful operation with superior fuel efficiency. The Cat C27 engine powers the loader and delivers net power of 699 hp (521 kW). Lower engine speed helps drive economi- cal fuel use. Additional fuel savings accrue with the ECO Mode (on-demand throttle), engine-idle shutdown system, and engine-idle kickdown/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, increased productivity. The EC210D features increased hydraulic flow for responsive, accu- rate control in grading and combined operations. Operators benefit from smoother, easier movement when traveling and lifting simultaneously as well as better grading quality from the harmonized boom and arm movement. The Volvo EC210D is designed for optimum profitability. Offering improved fuel efficiency and Volvo’s ECO mode, the excavator lowers fuel consumption and reduces operat- ing costs. The intelligent ECO mode contributes to the machine’s total improved fuel efficiency – without any loss of performance. The design optimises flow and pressure while maintaining digging power and swing torque. Built with durable components for outstanding results in all applications, the EC210D is designed to secure lasting machine value and an excellent return on investment. l

and reduce heat – especially in load- and-carry applications. The system allows operators to balance rimpull and hydraulic power for optimum loading efficiency. Positive Flow Control imple- ment hydraulics use a variable displace- ment, electronically controlled pump to precisely apportion oil flow based on operator control inputs. l The Cat 990K Aggregate Handler has a payload of 20 tonnes and a full turn static tipping load of 43 738 kg.

has a payload of 20 tonnes and a full turn static tipping load of 43 738 kg. Additional counterweight maintains machine stability, and robust 990K struc- tures ensure durability in the Aggregate Handler configuration. The loader makes best use of general purpose and coal available in standard lift configuration with a 4 108 mm dump clearance and in high lift configuration with 4 569 mm dump clearance. Increased capacity and high dump clearance enable customers to load railcars and large trucks with a buckets for increased volume. The 990K Aggregate Handler is The EC210D crawler excavator from Volvo Construction Equipment is designed with Volvo’s extensive experi- ence and expertise for ultimate produc- tivity and efficient operation in a wide variety of tasks. The machine features a robust frame combined with optimal engine power and hydraulic pressure to provide superior digging forces and fast cycle times for excellent productivity in all operations. A powerful Volvo engine works together with the machine’s proven hydraulics to provide high torque at low rpm for the ultimate combina- tion of performance and improved fuel efficiency. For fast cycle times and optimum fuel consumption, the EC210D is equipped with intelligent work modes, including the new G4 work mode. Operators can choose the best mode to suit the task at hand, selecting from I (Idle), F (Fine), G (General), H (Heavy) and P (Power max) mode. Choosing the correct mode according to working condi- tions ensures added versatility and
