990K created for several lives. To help extend the life of the machine, Caterpillar offers a range of sustainable options, such as our Reman and Certified Rebuild programs. In these programs, reusable or remanufactured components can provide cost savings of 40 to 70 percent, which reduces operating costs.

Caterpillar offers retrofit packages that allow you to use new features on older machines and maximize your resources. And when you complete the Cat Certified Rebuild program, these upgrade kits are part of the recovery process.

EFFECTIVE COMBINATION

For full trucks with minimal loading time, an efficient loading / transport system starts with perfect fit. Cat wheel loaders are combined with Cat off-road dumpers to maximize the amount of material being moved with minimal operating cost per ton. Model 990K, equipped with a standard hitch, will pass 773 (54 tons / 60 tons) in 3 passes and 775 (64 tons / 70 tons) in 4 passes. Equipped with a high-lift linkage, the 990K can load 777 (91 tons / 100 tons) in 6 passes.

BUCKET GROUND INSTRUMENTS

Increase your loader`s productivity and protect your investment in buckets with our ground tools (GET). Your knowledgeable Cat dealer will work with you to understand your application and the GET needs that best suit you.

LEADING SERIES

Performance buckets are characterized by an optimized profile that maximizes material retention and minimizes digging time, which leads to a significant increase in performance and fuel efficiency. All 990K buckets are manufactured with the Performance series design.

ROCK BUCKET

Scopes: face loading of densely condensed pit materials.

BUCKET GENERAL PURPOSE

Application areas: bulk solids loading.

GET OPTIONS

Many GET options are available to customize your 990K for your application, such as:

Side defenders.

General responsibilities and penetration tips.

Standard and half boom segments.

OPERATING COSTS

Customer data shows that Cat wheel loaders are among the most economical machines in the industry.

Several features contribute to this excellent fuel efficiency:

Performance Series Buckets - Provides faster filling times and better material retention, ultimately reducing cycle time while improving performance and fuel efficiency.

Hydraulics with positive flow control - provides only the hydraulic flow required by the systems of the unit to increase fuel efficiency and increase traction.

ACERT Engine - Advanced Engine Management maximizes power and efficiency

Eco mode - thanks to throttle on demand, eco mode optimizes power for maximum fuel economy with minimal impact on production.

Shutting down the engine at idle - automatic shutdown of the engine and electrical system saves fuel.

Torque converter lock - transfer more power to ground and optimize fuel consumption in all applications.

The configuration of the machine, the operator`s technique and the location of the working platform can affect fuel consumption.

Machine Configuration — Choose the right tool and type of tire for your application. Provide proper inflation pressure. Use the economy mode setting for maximum efficiency.

Platform Layout - Locate the loading targets in the correct position. Avoid traveling more than 1.5 tire turns during truck loading cycles. Reduce transport distance for loading and carrying cycles, optimizing the layout of the working area.

Loading bucket - loading in first gear. Quickly lift and tilt the bucket and do not use the “swinging” movement. Avoid locking the lift lever and use the impeller clutch.

Loading a truck or bunker - Do not raise the working tool above the required level. Maintain low engine speeds and discharge in a controlled manner.

At idle - engage the parking brake to activate the engine idle speed control system.
