Connect directly to the machine for access to a wide range of sensor information and enhanced machine data.
Create productivity reports with payload and work cycle segmentation.
Identify operator training needs through productivity data.
Detailed data logging of machine parameters and diagnostic codes.
Track machine sensor information with trend analysis and histograms to monitor machine health.
Sustainability is designed and built into our 988K's features.
Burns up to 20% less fuel than the previous model to minimize your carbon footprint.
Engine Idle Shutdown can help you save fuel by avoiding unnecessary idling.
Reduce waste with our maintenance free batteries.
Built for multiple lives, the Cat 988 is one of the most rebuilt products. To assist with maximizing machine life, Caterpillar provides a number of sustainable options such as our Reman and Certified Rebuild programs. In these programs, reused or remanufactured components can deliver cost savings of 40 to 70 percent, which lowers operating cost while benefiting the environment.
Caterpillar offers retrofit packages to bring new features to older machines, maximizing your resource. And, when you go through the Cat Certified Rebuild program, these retrofit kits are part of the rebuild process.
For full truck payloads with minimum loading time, an efficient loading/hauling system starts with a perfect match. Cat wheel loaders are matched with Cat off-highway trucks to maximize volume of material moved at the lowest operating cost per ton. The 988K equipped with the standard linkage will pass match the 770 (36 tonnes/40 tons) in 3 passes and the 772 (45 tonnes/50 tons) in 4 passes. Equipped with a high lift linkage the 988K is capable of loading a 773 (56 tonnes/61.7 tons) in 5 passes and the 775 (64 tonnes/70 tons) in 6 passes.
Enhance the productivity of your loader and protect your investment in buckets with our Ground Engaging Tools (GET). Your knowledgeable Cat dealer will work with you to understand your application and needs for the GET that is best for you.
Performance Series Buckets
Performance Series Buckets feature an optimized profile maximizing material retention and minimizing dig time, translating into significant productivity and fuel efficiency improvements. All 988K buckets are manufactured with the Performance Series design.
Applications: Face loading tightly compacted pit materials.
General Purpose Bucket
Applications: Loading loose, stockpiled material.
Multiple GET options are available to customize your 988K to your application, such as:
Data from customer machines show Cat wheel loaders are among the most fuel efficient machines in the industry. Several features contribute to this excellent fuel efficiency:
Performance Series Buckets - Deliver faster fill times and better material retention, ultimately reducing cycle times while improving productivity and fuel efficiency.
Positive Flow Control Hydraulics - Provides only the hydraulic flow required by the implement and steering systems for improved fuel efficiency and greater rimpull.
ACERT Engine - Advanced engine controls maximizes power and efficiency.
Economy Mode - Featuring On Demand Throttle, Economy Mode optimizes power for maximum fuel savings with minimal impact on production.
Engine Idle Shutdown - Automatic engine and electrical system shutdown conserves fuel.
Lock up Torque Converter - Transfers more power to the ground and optimizes fuel efficiency in all applications.
Advanced Productivity Electronic Control Strategy (APECS) - All new APECS transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points. Machine configuration, operator technique, and job site layout can impact fuel consumption.
Machine Configuration - Select the correct work tool and tire type based on machine application. Ensure proper inflation pressures. Utilize the Economy Mode setting for maximum efficiency.
Job Site Layout - Spot loading targets in the right position. Avoid traveling more than 1.5 tire revolutions during truck loading cycles. Reduce transport distance for load and carry cycles by optimizing job site layout.
Loading Bucket - Load in first gear. Raise and tilt bucket quickly and do not use a “pumping” motion. Avoid lift lever detent and use impeller clutch.
Loading Truck or Hopper - Do not raise the work tool any higher than necessary. Keep engine rpm low and unload in controlled manner.
Idle - Set the parking brake to engage Engine Idle Management System.
