POSITIVE FLOW CONTROL HYDRAULICS
The 988H Positive Flow Control (PFC) Hydraulic System is highly effective . Lowers fuel consumption,gives better hydraulic response allowing operator better control of the bucket. Also improves power efficiency and lowers system heat.
Lift Cylinder Increase and Regen Valve Retrofit Kit.: Both of these features improve dig cycle through improved control and lift force capacity.
Payload Control System. The new Payload Control System 3.0 helps you manage truck payloads and produce accurate records of material being moved. This advanced electronic control system is designed for on-the-go weighing and gives significant improvement to the operator interface.
Planetary Powershift TransmissionThe planetary powershift transmission comes with the Impeller Clutch Torque Converter (ICTC) and Rimpull Control System (RCS). Transmission clutch control provides improved shift quality, component life and operator comfort
Automatic Kickouts. Operators can easily set the dump height, return to dig/carry or bucket angle from the comfort of the cab. Standard, in-cab programmable kickouts, located in the upper left hand switch panel. This feature provides more flexibility and improved productivity when the job requires load and dump target heights.
Lower Operating Cost/Serviceability
988H FUEL MANAGEMENT SYSTEM
The Cat® 988H Wheel Loader Fuel Management System delivers superior productivity and fuel savings . With the 988H fuel management system,it will be easy for you to choose the level of fuel savings you want to achieve. By simply setting a rocker switch in the cab, you can easily accommodate changing production demands by moving between three modes of operation: Full power mode, balanced power mode,maximum fuel savings mode.
AUTO IDLE KICKDOWN (AIK)
If an operator is not actively operating the 988H for a specific period of time, the AIK system will temporarily reduce the engine speed to save fuel. Afteran e automated engine speed reduction, the system will automatically resume the engine speed to the previous setting when the operator engages the implement control pod of the F-N-R switch or the STIC Steer.
ENGINE IDLE SHUTDOWN
This feature automatically shuts down the engine after the machine has been in a safe idling state for an extended amount of time. The operator in the cab will be audibly and visually warned before the shutdown occurs.
Operator and job site efficiency
IMPELLER CLUTCH TORQUE CONVERTER (ICTC) AND RIMPULL CONTROL SYSTEM (RCS)
ICTC combined with the RCS allows the operator maximum flexibility in the modulating rimpull.
Left brake pedal modulates rimpull from 100 to 25 percent for reduced tire slippage and wear. After 25 percent is achieved, further pedal travel applies the brake.
RCS reduces the potential for wheel slippage without reducing the hydraulic efficiency. An in-cab switch allows the operator to set percentage of maximum rimpull to meet operating
conditions. Four settings are available, and operators can set rimpull at 70, 80, 90 and 100 percent.
A lock-up clutch torque converter provides direct drive efficiency which translates into improved fuel efficiency in certain applications.
VARIABLE SHIFT CONTROL
VSC matches transmission shifting patterns to machine application requirements, by shifting at lower engine rpms. This improves both shift quality and fuel efficiency in certain applications.
The Cat® C18 engine with ACERT® Technology features increased horsepower and efficient fuel management for quick response, high productivity and exceptional service life. A sculptured cylinder block provides greater strength and is lighter weight.
Combining the use of robotic welding and castings in critical high-stress areas, more than 90 percent of the 988H structure is robotically-welded to provide highly consistent welds and increased strength. Castings are also used in several areas to increase strength by helping to spread the loads and reduce the number of parts.
FRONT FRAME AND REAR FRAME
Highly engineered and a field-proven combination, the 988H uses high-strength plates and castings which distribute loads and increases structure robustness. A key differentiator from other manufacturers’ machines is the box-section rear frame and box-shaped loader tower. The box section absorbs torsional forces generated in a loading cycle, maintaining alignment for hitch pins and driveline. The box-shaped loader tower resists shock and torsional loads, maintaining hitch and loader linkage pin alignment, maximizing pin life.
The 988H features the revolutionary box boom linkage design. Known for its durability, the 988H box boom linkage has high strength castings in pin joint areas that resist twisting and minimize stress. A B-pin bucket mount is placed at a height to prevent bucket healing due to better stress distribution from bucket to boom. Additionally, a four-hinge plate bucket design is utilized to increase bucket durability.
AXLE-SHAFT, OIL DISC BRAKES
These brakes are adjustment-free, fully hydraulic and completely sealed. Disc face grooves provide cooling even when brakes are applied for a longer component life.
Location of the brakes allow for improved serviceability. The axle shaft brake design allows for brake service while leaving the final drive intact.
Axle-shaft brakes require less force by operating on the low torque side of the axle. Combined with improved axle oil circulation for increased cooling, the oil-enclosed, multiple
disc brake design improves durability.
BEST-IN-CLASS WORKING ENVIRONMENT
988H has a best in-class working environment with a cab designed for optimum operator comfort, visibility and ease of operation.Ergonomic controls are fully adjustable with switches and controls located within easy reach of the operator.The interior noise levels are reduced to a quiet 72 dB(A).The Monitoring System (EMS-III) provides information on machine’s major components. There are optional features available for improved visibility. These options include a rear vision camera to clearly monitor movement behind the wheel loader and high intensity discharge (HID) lights for greater visibility at night.
