Manufacturer of construction and mining machines Caterpillar has introduced its seventh-generation Cat 988K Wheel Loader.
The introduction marks the 50th anniversary of the 988 delivering performance for worldwide customers.
Fuel efficiency is enhanced by up to 20 per cent compared to the 988H, with the electronic fuel control. It also includes the 988K Mode (on-demand throttle), engine-idle shutdown system, and engine-idle kickdown/auto-resume system.
The new operator stations features the next generation Vital Information Management System (VIMS). This provides real-time fuel consumption and fuel efficiency data through an interactive touch screen. In-cab sound levels are reduced to 71.1 dB(A), from 74.2 dB(A) in the 988H.
It is designed as an optimum loading tool for Cat construction and mining trucks. It includes 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 and is available as a Tier 4 Final/Stage IV version, using selective catalytic reduction to control nitrogen-oxide emissions. It is also available as a Tier 2/Stafe II version for less regulated areas.
It also comes with the optimised Z-bar loader linkage and expands its versatility in small quarries and underground applications. This uses solid steel lift arms in either a standard or high-lift configuration, decreases machine height at maximum lift yet increases dump clearance. The shorter machine length means better manoeuvrability.
The impeller clutch torque converter uses a lock-up clutch for direct drive. This cuts cycle times and reduces heat especially in load-and-carry applications. The system lets operators balance rimpull and hydraulic power for efficient loading.
The impeller clutch torque converter uses a lock-up clutch, with direct drive to boost fuel.
It also includes a remote panel with a stairway light switch, engine shutdown switch, and lockouts for the transmission and engine starter. A second panel comes with access to the battery disconnect switch and a jump start receptacle.
A rear view camera system provides images through the in-cab monitor. There is easy access to maintenance points including hydraulic pressure taps and oil sampling ports.
