Caterpillar roll out new 990K wheel loader

Cat 900K wheel loader

Latest wheel loader model offers increased productivity, improved safety and greater operator efficiency

ACCORDING to Caterpillar, the new 990K wheel loader offers more power and increased payload for greater productivity and fuel efficiency compared to its 990H predecessor. The machine has a redesigned cab that delivers a superior operator interface and quiet environment, while several new features promote operator and maintenance technician safety and performance.

Designed as an optimum loading tool for Cat quarry trucks, specifically the 773, 775 and 777 models (ranging from 54 to 91 tonnes capacity), the new 990K also features engine configurations to meet customer needs worldwide.


The wheel loader offers a 16-tonne payload – up from the 15-tonne payload of the H Series model. The increased payload makes the new loader a perfect four-pass match with the Cat 775 truck for efficient, high-production loading.

A Cat C27 ACERT engine powers the 990K and delivers an 11% increase in power compared to the previous model. Net power of 699hp (521kW) also helps deliver increased production—without any change in fuel consumption, while reduced engine speed helps drive economical fuel use. Further fuel savings can be generated with the machine’s Eco mode (on-demand throttle), engine-idle shutdown and engine-idle kickdown/auto-resume system.

The 990K is available in a Tier 4 Final version or Tier 2 model for less regulated regions. No regeneration or operator intervention is required on the NOx-reduction system and diesel oxidation catalyst on the Tier 4 Final model.

The Cat exclusive, field-proven impeller clutch torque converter on the wheel loader 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 also allows operators to balance rimpull and hydraulic power for optimum loading efficiency.

The redesigned cab allows easy access and egress, and features noise suppression delivering a benchmark sound level of 69.9dB(A) for superior operator comfort. In addition, a Cat Comfort III seat provides integrated seat-mounted controls for smooth and comfortable operation.

For added safety, the 990K machine is equipped with a Cat Vision rear-view camera system and in-cab display to show the operator the area behind the loader. A 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.

For enhanced serviceability, a remote panel houses a stairway light switch, engine shutdown switch and lockouts for the transmission and engine starter. A second panel provides convenient access to the battery disconnect switch and a jump-start receptacle, while routine maintenance points are easily accessed, including hydraulic pressure taps and oil sampling ports.
