Introduced in 1963, the 988 has been the industry leader for 50 years. Focused on helping our customers succeed, we have continued to build upon each new series. The 988K continues our legacy of reliability, performance, safety, operator comfort, serviceability, and efficiency. The Cat 988K Block Handler was designed to withstand the demanding and harsh environment of block handling applications. The features of the 988K Block Handler work together to provide a durable and reliable machine to meet your block handling needs.
The Cat C18 ACERT engine is built and tested to meet your most demanding applications while meeting U.S. EPA Tier 4 Final/EU Stage IV, Tier 2 Equivalent emission standards.
Fully integrated electronic engine controls works in concert with the entire machine to make your fuel go farther.
Use less fuel idling with Engine Idle Shutdown.
Maximized durability with Delayed Engine Shutdown.
Cat Planetary Powershift Transmission
Featuring all new Advanced Productivity Electronic Control Shifting (APECS) transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.
Impeller Clutch Torque Converter (ICTC)
Enable your operators to maximize efficiency by varying machine rimpull while putting more horsepower to hydraulics.
Reduced tire wear
Enables full throttle shifts for faster cycle times
Provides smooth approach to the dump target for less spillage and faster cycle times.
Cat Torque Converter with Lock-up Clutch
Eliminates TC losses while lowering system heat
Improves travel speeds
Reduces cycle times in load and carry operations
Enabling maximum productivity and efficiency, all day every day. The 988K systems work hard to save you fuel through advanced technologies. Utilizing On Demand Throttle, operators maintain normal operation with the left pedal and implements while the 988K manages the engine speed.
Provides similar control and feel to our traditional throttle lock feature.
Efficiency of manual throttle and the ergonomics of throttle lock.
Reduced fuel consumption by up to 20% compared to the 988H.
The 988K Block Handler delivers stability and durability with an optimized counterweight for block handling applications.
High Rimpull Power Train
The 988K Block Handler is capable of moving the heaviest blocks out of your quarry pit. The high rimpull power train features a torque converter and transmission specially designed for this application to maximize rimpull.
Quick Coupler Activation
The Block Handler includes an additional hydraulic valve with the Quick Coupler, allowing the operator to switch work tools and immediately lock the work tool during load and carry applications.
Larger Tilt and Lift Cylinders
The 988K Block Handler comes equipped with larger tilt and lift cylinders on the linkage that help improve load control and ensure safe and long lasting operation.
Ride control works by using an accumulator to dampen the linkage motion, acting as a shock absorber. It provides the operator with a smoother ride over rough terrain, enabling a more comfortable ride at higher speeds.
Optimized Z-bar Linkage
Linkage layout designed to maximize lift capability in block handling application.
High load stresses are absorbed by solid steel lift arms.
Enhanced strength in key pin areas through the use of one piece castings.
Stress released lift arms increase durability and lengthen time to repair.
Increase efficiency through our Positive Flow Control (PFC) Hydraulic System. PFC has concurrent pump and valve control. By optimizing pump control, hydraulic oil flow is proportionate to implement lever movement.
Fast, productive cycles are enabled by the fully variable implement pump.
Increase bucket feel and control through increased hydraulic response.
Consistent performance and efficiency with lower system heat.
Full hydraulic flow down to 1,400 engine rpm enabled by flow sharing technology.
Electro Hydraulic Controls
Operators increase productivity with our responsive implements feature.
Operate comfortably through electronically controlled hydraulic cylinder stops.
Handle easy-to-use soft detent controls.
Conveniently set automatic implement kickouts from inside the cab.
Confident loader operation starts with precise machine control enabled by the 988K's load sensing hydraulic steering system.
Increase efficiency with our variable displacement piston pumps.
Enhance operator comfort with integrated steering and transmission control functions.
Benefit from extended performance and reliability of your hydraulic system with our advanced filtration system.
The 988K electronic systems have been completely integrated to function as one machine. This integration creates a smart machine and more informed operator, maximizing the productivity of both.
Cat Product Link™
Cat Product link allows remote monitoring of equipment to improve overall fleet management effectiveness. Events and diagnostic codes, as well as hours, fuel, idle time and other information are transmitted to a secure web based application, VisionLink®. VisionLink includes powerful tools to convey information to users and dealers, including mapping, working and idle time, fuel level and more.
We have worked hard to help our customers and operators perform at their best through our Vital Information Management System (VIMS 3G).
Easy-to-view graphical information display features a large touch screen interface.
Intuitive operation and easy navigation with our enhanced user interface.
Decrease service time by keeping operators informed about machine system malfunction or operation.
The quick coupler is designed for optimal utilization of lifting and break-out forces with Cat cylinder, safety valves, pressure and isolating valves, safety covers and lock indicators. It has enhanced visibility and has been optimized for handling large rocks and blocks.
(2) Breaker Tine
Center-mounted, heavy-duty single-piece forged fork tine is used for prying loose large stone blocks. It is built with an extra thick tine to handle a variety of materials in this demanding application.
Heavy-duty pallet forks are engineered to handle weight and load stress when maneuvering and placing blocks in quarry operations. Dual tine forks are designed to allow blocks to be placed close to the machine for greater balance and safe handling.
(4) Clearing Rake
Used primarily for clearing and controlling loose objects at the quarry face and working levels, the block handling rake is designed with a curved boom for enhanced operator visibility and object placement.
(5) Rock Bucket
Heavy-duty bucket offers superior durability, protection and performance in rock and overburden operations in block quarries. It includes large size teeth and segments. Its HD400 (high wear resistant) metal shell and bottom offer maximum strength, durability and wear life.
(6) Marble Bucket
Special bucket construction including the HD400-metal shell and bottom help the bucket effectively load large blocks and boulders while maintaining durability. The corner teeth ease block tilting and handling. The heavy-duty V-edge is particularly suited for handling high-value breakable marbles before cutting operations.
(7) Block Bucket Heavy-Duty
Special bucket construction loads very large squared blocks and boulders. The deep carved sides and extra long heavy-duty bottom allow the special V-edge to penetrate under large blocks. The interior bucket profile allows blocks to further fit back in the bucket for increased load and lift capabilities and better balance and rack-back. Its HD400-metal shell and bottom offers maximum strength, durability and wear life.
