Structures and Fabricated Box Boom
The articulated frame design features a high-torsion, compact, load-absorbing, front frame and a large, box-section, engine-end frame. Fabricated boom and linkage geometry increases dump clearance, provides improved breakout and lift forces and increases the viewing area to the bucket corners.Power Train
The Cat C18 engine with ACERT™ Technology is EU Stage IIIA compliant. The Cat transmission and impeller clutch torque converter offer smooth, consistent shifting with fingertip control. Electronic controls help increase productivity.Hydraulics and Electronic Monitoring
Innovative electro-hydraulics play a key role in performance of the 988H and provide low operator effort. Increased hydraulic efficiency improves lift and tilt cycle time for reduced overall cycle time. The tradition of reliable, high-performance Caterpillar hydraulics continues.Operator Station
Experience a new level of efficiency, comfort and productivity with one-hand STIC operation, a large cab, low-effort, fingertip lift and tilt controls, improved visibility, reduced sound levels, improved ventilation and easier entry and exit.Buckets and Ground Engaging Tools
Choose between 6.3 m3 and 7.0 m3 capacity buckets, spade edge and straight edge buckets and various Ground Engaging Tools to match job conditions. Cat buckets retain the proven shell-tine construction design for unmatched durability.Bucket Match
Improve machine performance and increase stability by selecting the right bucket for your application and material density.Application Truck Match
Increased performance and good pass matching make the 988H a versatile performer.Maintenance and Serviceability
Most daily maintenance checks are performed from the machine’s left side, facilitating quick start up. Case drain filters for main hydraulic, steering and fan pumps protect against contamination, and remote pressure taps contribute to improved serviceability. Easy access to major components enhance serviceability and increase uptime.Customer Support
