Caterpillar introduce the 988K wheel loader

Cat 988K wheel loader

New machine features efficient new loader linkage, expanded versatility and greater fuel efficiency

DESIGNED as an optimum loading tool for Cat construction and mining trucks, the new, seventh-generation 988K wheel loader features a redesigned loader linkage, worldwide engine configurations, drive train modifications, redesigned cab and enhancements in safety and serviceability.

The 988K is powered by the  Cat C18 ACERT engine, which is available as a Tier 4 Final/Stage IV version (using selective catalytic reduction to control nitrogen-oxide emissions), and as a Tier 2/Stage II version for less-regulated regions.


Electronic fuel control ensures optimum performance and throttle response, delivering up to 20% greater fuel efficiency, compared with the 988H. Additional fuel savings accrue with the 988K ECO Mode (on-demand throttle), engine-idle shutdown system, and engine-idle kickdown/auto-resume system.

The patented optimized Z-bar loader linkage replaces the 988H mono-boom design and expands the 988K’s versatility in small quarries and underground applications. The new design, using solid steel lift arms in either a standard or high-lift configuration, reduces machine height at maximum lift yet increases dump clearance, and also shortens machine length for greater manoeuvrability.

The exclusive Cat 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, while the automatic retarding control (ARC) system utilizes the optional compression brake to maintain desired downhill speeds and reduce service brake wear.

An all-new operator station featuring Caterpillar’s next-generation Vital Information Management System (VIMS) provides expanded capabilities, including real-time fuel consumption and fuel efficiency (material loaded per unit of fuel) data, through an interactive touch screen. A rear-view camera system provides sharp images via the in-cab monitor.

In-cab sound levels are considerably reduced, down from 74.2 dB(A) in the 988H to 71.1 dB(A) in the 988HK, while the Cat Comfort III seat features integrated controls for smooth and comfortable operation. Transmission controls, integral with the STIC steering lever, allow convenient travel control.

For added safety, 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. Routine maintenance points are easily accessed, including hydraulic pressure taps and oil-sampling ports.

Options for the 988K include the Cat Payload Control System and Cat Detect Object Detection, which builds on the Cat camera system with radars and in-cab software that provide notification to the operator when an object is detected within the radar coverage area.

Other options include an integrated axle cooling package, ride control, fast-fill fueling system, automatic lube system, three-spool valve, high-speed oil-change system, LED lighting, cold-start package, and the Cat Product Link telematics system.

Caterpillar introduced and displayed the new 988K at the Bauma trade show earlier this year, although the loader will not be available commercially until August.
