Caterpillar has introduced its 990K Aggregate Handler, which is designed to handle greater payloads in aggregates yard applications. With a payload increase of as much as 25%, as compared to the standard 990K, the new system allows customers to load trucks and railcars faster, as well as enabling them to move more material in load-and-carry and stockpile management tasks.
With a payload of 22 t and a full turn static tipping load of 96 426 lb., machine stability is maintained by additional counterweight and robust 990K structures ensure durability in the configuration of the aggregate handler. For increased volume, the loader makes best use of general purpose and coal buckets.
The handler is available in standard lift configuration, with 13.5 ft dump clearance, as well as in high lift configuration, with 15 ft dump clearance. This increased capacity and high dump clearance enables customers to load railcars and large trucks with better pass match for faster material handling at a lower cost per tonne.
Building on the 990K
The new handler is built on the proven features of the 990K wheel loader. The 990K powertrain provides powerful operation with superior fuel efficiency. The Cat® C27 engine powers the loader and delivers a net power of 699 hp (521 kW) and lower engine speed helps to drive economical fuel use. Fuel savings also accrue with the ECO mode (on-demand throttle), engine-idle shutdown system, and engine-idle kickdown/auto-resume system.
Exclusive to Cat, the field-proven impeller clutch torque converter uses a lock-up clutch. This provides direct drive to boost fuel economy, trim cycle times, and reduce heat, particularly in load-and-carry applications. Operators are also able to balance rimpull and hydraulic power for optimum loading efficiency. Positive flow control implement hydraulics use a variable displacement, electronically controlled pump to precisely apportion oil flow based on operator control inputs.
Various drivetrain options are also available, while the integrated axle cooling and ride control options are particularly beneficial in load-and-carry work.
Featuring the Cat Vital Information Management System, VIMSTM 3G, which provides customisable operator profiles, the system also includes a cycle timer, and an integrated payload control system, for on-the-go payload weighing. Graphical information is displayed in an easy-to-use manner, keeping key information in the front of the operator. A Cat Comfort III seat provides seat-mounted controls for smooth and comfortable operation. Integral with the STICTM lever, transmission controls allow convenient travel control.
Equipped with a Cat Vision rearview camera system and in-cab display, the system is also able to show the operator the area behind the loader. A Cat Detect object detection system is also available as an option, building on the camera system with radars and in-cab software that notify the operator when an object is detected within the radar coverage area. The systems are designed to enhance operator awareness, particularly in congested loading areas.
