THE new Cat 990K Wheel Loader offers more power and increased payload for greater productivity and fuel efficiency. The 990K also features a redesigned cab that delivers a superior operator interface and a quiet environment, and several new features promote operator and maintenance technician safety and performance.

Designed as an optimum loading tool for Cat construction and mining trucks, the new 990K also features engine configurations to meet customer needs worldwide. The 990K builds on the proven features of previous models and replaces the 990H.

The rated payload of the new 990K is 16 tonnes, up from the 15-tonne payload of the H Series model. The increased payload makes the new loader a perfect 4-pass match with the Cat 775 truck for efficient, high-production loading. New, Performance Series Buckets promote fast filling and full bucket loads on every pass, and they are available in sizes ranging from 8.6 to 10.0 cubic metres.

The Cat C27 ACERT engine powers the 990K and delivers an 11% increase in power compared to the previous model. Net power of 521kW helps deliver increased production without any change in fuel consumption. Lower engine speed helps drive economical fuel use. Additional fuel savings accrue with the 990K ECO Mode (on-demand throttle), engine-idle shutdown system, and engine-idle kickdown/auto-resume system.

The 990K is available as a US EPA Tier 4 Final version and as a Tier 2 version for less regulated regions. No regeneration or operator intervention is required for the NOx reduction system and diesel oxidation catalyst equipping the Tier 4 Final model. And there is no increase in fuel consumption as a result of the engine emissions control systems.

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 loading efficiency. Positive Flow Control implement hydraulics use a variable displacement, electronically controlled pump to precisely apportion oil flow based on operator control inputs.

The redesigned cab allows easy access and egress and features noise suppression that delivers a benchmark sound level of 69.9 dB(A) for superior operator comfort. 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 operator station also 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.
