Benefits & Features

Productivity

Engine

The Cat® C27 engine with ACERT® Technology is U.S. EPA Tier 3 and EU Stage III compliant. It features increased horsepower and efficient fuel management for quick response, high productivity and exceptional service life. A sculpted cylinder block provides greater strength and is lighter weight.

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 20 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.

Fuel Efficiency

Load Sense Steering System

Typical steering systems can draw more than 30 kW (40 hp) from the engine. The draw is constant, even when the operator is not steering. This system maximizes performance by directing power through the steering system only when it's needed. More efficient use of power results in decreased fuel consumption and higher production.

Torque Converter Lock Up Clutch

The torque converter lock up clutch provides direct drive for improved fuel economy, especially in load and carry operations. This feature activates in second and third gears forward and first through third gears reverse.

Demand Driven Cooling Fan

A variable displacement pump drives the fan's hydraulic motor so that fan speed varies independent of engine speed. The pump increases output as temperatures increase, improving cooling capability. The fan draws only the power needed for cooling, reducing fuel consumption and increasing efficiency.

Engine Idle Shutdown

This new feature will automatically shutdown 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.

Reliability

Structures

Combining the use of robotic welding and castings in critical high-stress areas, more than 80 percent of the 990H 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 field-proven, the 990H 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.

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 allows 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.

Z-bar Loader Linkage

Proven Z-bar loader linkage geometry delivers maximum productivity. Fewer pivot points and moving parts are designed to reduce maintenance costs.

Operator Comfort

Best-in-Class Working Environment

    A comfortable operator is a productive operator, which is why Caterpillar has designed the 990H with a best-in-class working environment for this size wheel loader class.
    • World class cab incorporates features for operator comfort and ergonomics, visibility and ease of operation.
    • Ergonomic controls are fully adjustable and designed for low-effort comfort. Switches and controls for various systems are located within easy reach of the operator.
    • Interior noise levels are reduced to a quiet 72 dB(A).
    • Cat Monitoring System (EMS-III) provides information on machine's major components. This includes gauge displays for the fuel tank level; temperature gauges for the engine coolant, torque converter and hydraulic oil; tachometer analog gauge with digital readout for gear selection and ground speed and a monitoring system.
    • Optional features are 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.
    • Standard trainers seat allows for a safe method to properly train your operator.

Technology Solutions

Payload Control System

Payload Control System (PCS) is designed to help the 990H owners and operators manage truck payloads and produce accurate records of material movement. This advanced electronic control system is designed for on-the-go weighing.

Cat Product Link

    Cat® Product Link enables convenient, remote monitoring of equipment. It provides usable information to keep jobs on schedule, maintain machine health and reduce fleet owning and operating costs.
    • Simplify fleet management and monitor machine use
    • Link all machines, regardless of brand
    • Three levels of insight to meet specific business requirements

Cat Detect

Using a combination of radars, an in-cab display, and multiple cameras, Cat Detect provides equipment operators with enhanced awareness for increased site safety. The touch screen display alerts the operator when objects have entered critical areas around the equipment. The radar view provides a visual indication of where the objects are relative to the machine.

Buckets and Ground Engaging Tools

Buckets

Buckets for the 990H range in size from 8.6 m3 (11.25 yd3) to 9.2 m3 (12 yd3) and may be configured for a variety of impact and abrasive conditions. All buckets are built with shell-tine construction that resists twisting and distortion and feature replaceable, weld-on wear plates to protect the bottom of the bucket. The integral rock guard helps retain big loads while heavy-duty pins and retainers provide durability.

Rock Buckets

Available in spade edge or straight edge configurations. Spade edge buckets use bolt-on segments and are available from 8.6 m3 (11.25 yd3) to 9.2 m3 (12 yd3). An 8.6 m3 (11.25 yd3) Straight Edge Rock is also available. Each bucket accepts up to two sets of sidebar protectors, features double-strap adapters, easily changed bolt-on segments and several tip options.

Heavy-Duty Quarry Bucket

Available as an 8.6 m3 (11.25 yd3) capacity bucket and is recommended for use in face loading where moderate abrasion and high impact is encountered. It features additional wear protection items, including: thicker base edge and adapters, additional liners and wear plates, bolt-on half arrow segments and four sidebar protectors.

High Abrasion Bucket

Available as an 8.6 m3 (11.25 yd3) capacity bucket and is recommended for use in face loading where high abrasion and moderate impact is encountered. This bucket features additional wear protection items including independently attached edge and adapter covers, flush mount adapters, additional liners and wear plates, four sidebar protectors (two sets) and a thicker base edge. Flush mount adapters provide a smooth finish floor and reduce wear on the adapters.

Serviceability

    The 990H is designed to ensure minimal downtime through ground level or platform access, grouped service points, and attention to key serviceable areas on the machine.
    • Maintain three points of contact at all times through ground level or platform accessible service areas.
    • Ground level viewable site gauges on all major systems.
    • Ground level engine shutdown, battery disconnect switch and steering hitch lock lever allow service technicians to perform maintenance while the machine stays static.
    • Longer service intervals on fluids and filters.
    • Swing-out doors on both sides of the engine compartment provide easy access to the engine oil dipstick and filler spout, S·O·SSM ports, fuel filters, air conditioner compressor, engine oil filters, alternator, starting receptacle, air filter service indicator, cooler fill and ether starting aid.
    • Maintenance-free batteries
    • Ecology drains for ease of service and prevention of spilling potential environmental contaminants. Ecology drains are standard on the hydraulic, engine, transmission and coolant systems.
