Benefits & Features

Structures Combining the use of robotic welding and castings in critical high stress areas, more than 80 percent of Cat® Large Wheel Loader structures are robotically welded to provide highly consistent welds and increased strength. Castings are also used in several areas to increase strength by helping spread the loads and reduce the number of parts. Front Frame and Rear Frame Highly engineered and a field proven combination, Cat® Large Wheel Loaders use high strength plates and castings which distribute loads and increase structural robustness. A key differentiator from other manufacturers’ machines is the box section rear frame and box section loader tower. The box section absorbs tensional 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 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. Reliability Maximizing uptime, long life – it’s what you expect from your Cat Wheel Loader. » Learn More Operator Station Steel roof and cab skirts provide additional protection from heat and debris. Transmission Override A transmission override control in the cab allows the operator a secondary transmission control in the event of damage to transmission Electronic Control Module (ECM). The operator can select 1F or 1R to move the machine to a safe area for repairs to be made. Machine Guarding Front frame bottom guard and steering cylinder guards protect sensitive machine components from the effects of hot materials. Solid metal steps, profiled bumper guards and solid metal handrails are designed to survive tight working spaces. Hydraulic and Electrical System All exposed wiring harnesses and hydraulic hoses are insulated with protective sleeving to protect from extreme heat. Guarding on fuel and hydraulic tanks provides protection from puncture and excessive heat. Optional EcoSafe Hydraulic Fluid Fire resistant EcoSafe hydraulic fluid is available from the factory and is fully compatible with Caterpillar hydraulic system components. Extreme Temperature Axle Seals Caterpillar extreme temperature axle seals provide excellent sealing characteristics and life in the extreme heat of the still mill application. Parking Brake Override The parking brake override control, located at the rear of the bumper, allows the parking brake to be disabled with the engine not running. Steel Mill Specific Features Safeguarding the operator and critical machine components. » Learn More The 990H features are specifically designed to increase productivity on your job site. 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 sculptured cylinder block provides greater strength and is lighter weight. Steel Mill Arrangement Skull Handler (SMASH) The 990H SMASH arrangement provides unique lift and tilt cylinders and added counterweight to produce the lift and breakout forces necessary to handle heavy skulls. Productivity Designed with the right features to meet the daily demands of your job site. » Learn More 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 cabs incorporate 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). Caterpillar 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. New options to include heated seat for cold weather operations and radio offerings of Bluetooth, MPS and satellite options are now available. Operator Comfort Best-in-class working environment » Learn More Component Access 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, alternators, starting receptacle, air filter service indicator, cooler fill and ether starting aid. There are also ground level viewable sight gauges on all major systems and centralized remote pressure taps. Shutdown and Lockout Features An electrical disconnect switch and hydraulic lockout switch allow service technicians to perform maintenance while the machine stays static. Other shutdown or lockout devices include ground level engine shutdown and ground level steering hitch lock lever. Serviceability Easy to Maintain. Easy to Service. » Learn More Entry and Exit Getting on and off the machine is one of the leading causes of injury on a job site. Cat® Wheel Loaders have a number of features to ensure your operator gets safely on and off the machine. Features include primary and secondary stairwell exits, punch stamped tread plates, ground level nighttime stairwell light switch, full perimeter railings on upper platforms, side platform emergency egress and toe kicks and optional roading fenders. Rearview Camera With the new optional rearview camera, visibility is greatly enhanced. The camera is located in a pocket on the grill to protect it from damage and the elements. The camera can be set to activate only when the transmission is in reverse to help eliminate distractions in the cab, especially when in dark environments. Visibility Cat® Wheel Loaders offer a number of standard and optional features to enhance job site visibility. Standard and optional features include long life LED lights, articulated wiper/washer system with intermittent features, optional rear vision camera, optional high intensity discharge lights, optional warning beacon and optional turn signals.
