Heavy-duty aggregate handler boosts production in rehandling

A new heavy-duty handler is assisting producers to move more material more quickly in load and haul tasks.

The Caterpillar 990K aggregate handler is designed to handle greater payloads in aggregates yard applications. With as much as a 25 per cent payload increase compared to the standard 990K wheel loader, the handler enables customers to load trucks faster and to move more material in load and haul and stockpile handling tasks.

The 990K has a payload of 20 tonnes and a full turn static tipping load of nearly 44 tonnes. The additional counterweight maintains machine stability, and the robust 990K structure ensures durability in the aggregate handler configuration. The loader makes best use of general purpose and coal buckets for increased volume.

The aggregate handler is available in standard lift configuration with a 4.1m dump clearance, and in high lift configuration with 4.6m dump clearance. The increased capacity and high dump clearance enable customers to load large trucks with a better pass match for faster material handling at lower cost per tonne.

The 990K complements the smaller 986K and 988K aggregate handlers in the Caterpillar large wheel loader line. The aggregate handler, however, is not designed for use in quarry face or other shot rock applications.

The 990K aggregate handler is built on the proven features of the 990K wheel loader. The 990K powertrain offers plenty of “grunt”, with improved fuel efficiency. The Cat C27 engine powers the loader and delivers net power of 521kW.

A lower engine speed helps drive economical fuel use. Additional fuel savings can be accrued 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, and reduce heat — especially in load and haul applications.

The system allows operators to balance rimpull and hydraulic power for optimum loading efficiency. The positive flow control implement hydraulics use a variable displacement, electronically-controlled pump to precisely apportion oil flow based on operator control inputs.There are a number of drivetrain options available. The integrated axle cooling and ride control options are particularly beneficial in load and haul work.

The operator station features Cat’s Vital Information Management System (VIMS 3G), which provides customisable 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 information in front of the operator. The Cat Comfort III seat provides integrated seat-mounted controls for smooth, comfortable operation. Transmission controls, integral with the STIC steering lever, allow convenient travel control.

The 990K is equipped with the Cat Vision rear-view camera system and an in-cab display to show the operator the area behind the loader. The Cat Detect object detection system, available as an option, builds on the camera system with radars and in-cab software that provide notification to the operator when an object is detected within the radar coverage area. The systems are designed to enhance operator awareness, especially in congested loading areas.
