The revolutionary Adaptive Hydraulic System combines industry-leading and patent-pending dedicated pump-flow allocation technology with proven Cat features like independent oil cooling and boom float to generate flow and pressure, without waste – providing a 20% fuel efficiency advantage.

Dedicated Pump-flow Allocation Technology

• There are six main pumps, comprised of three identical double pumps, supply cylinders, travel motors and swing motors. Each of these main pumps can be used for any cylinder function, with priority to swing and travel.

• Pump flow of each circuit is directly controlled by the position of the joystick, which maximizes the hydraulic efficiency of the engine and dramatically reduces load factors.

• No oil flow must be throttled

• No high-pressure oil is returned to the tank

• Pump flow allocation can be supplied simultaneously to independent circuits (functions) or summarily for a single circuit (function), which enables the operator to directly control the speed of each function.

• More precise digging of slopes and trenches, especially on construction sites

• Faster cylinder speeds on production mine sites

Independent Cooling System

• The return oil cooling system is fully independent from the engine cooling system

• Cooler system temperatures extend component life

Boom Float

• During boom lowering, the float feature reduces engine demand

• Regeneration of boom oil increases energy efficiency

Serviceability

• Reduced load factors and efficiency gains are the basis for longer component life expectancies

• Hydraulic value block is mounted on the boom, providing easier access for service

Consistent Oil Cleanliness for Dependable Hydraulic System Performance

The hydraulic system design has been optimized for peak performance and reliability.

• Machine comes equipped with standard high-pressure and return oil filtration.

• A separate kidney loop provides continuous filtration and optimum oil cleanliness at all times, supporting the hydraulic system.

ADVANCED HYDRAULIC SYSTEM

• No excess oil flow

• No excess high pressure oil

• Lower hydraulic oil temperatures

• Less cooling required

ADVANTAGES

• Fuel Savings (20% MORE FUEL EFFICIENT)

• Performance

• Energy efficiency

• Component life

Protect and Extend the Life of Your Hydraulic Components and Seals

Providing an efficient means of cooling, particularly in demanding applications, our unique independent oil cooling system will extend the life of your hydraulic shovel's components.

More Efficient Oil Cooling

Our system is independent of return oil, achieving efficiency through the utilization of dedicated pumps that provide cooling capacity as needed, whether the engine is idling or under load. That means optimum oil temperature is being maintained, even while your operator waits for the next truck to load. Competitive hydraulic shovels only provide cooling when the machine is working and the engine is under load.

Additional efficiency is achieved via:

• Variable oil flow

• Variable fan speed

Optimal Oil Temperature Maintained

Our unique independent oil cooling system ensures that system operating temperatures remain within the optimal operating viscosity range at all times.

Simple and Cost-effective Single Engine Concept

When we asked you what design features you desired most from a 200 metric ton (220 short ton) size class hydraulic backhoe, a single-engine platform was a top request. We listened by designing the 6020B with a single C32 ACERT engine for reliable performance and simple and cost effective service when needed.

Reliable Cat C32 ACERT Engine

Delivering durable, reliable power that will keep your 6020B producing, the C32 ACERT has proven its ability to perform in harsh mining conditions throughout the world. Offering low operating costs, and supported 24/7 by your local Cat dealer, the C32 ACERT will help you achieve your production and profitability targets, reliably.

ACERT Technology

The development of ACERT Technology began with the search for a better way to reduce diesel engine emissions, and culminated in a revolutionary engine design breakthrough that burns fuel more precisely than ever before. Lower combustion temperatures reduce emissions and prolong the life of lighter, more power-dense engine platforms. It also varies the injection timing based on factors like engine load and speed for optimum performance under a wide range of operating conditions, including mining.

Worldwide Cat Engine Support

Our engines are only as good as the service and support that stand behind them. Highly trained and experienced service technicians at your local Cat dealership are ready with whatever you need, wherever and whenever you need it. They know the Cat C32 ACERT engine inside and out, so they can promptly diagnose issues and keep your 6020B running at peak performance.

Emissions Technology – Providing you reliable, integrated solutions.

See more

The 6020B is offered with two variations of the C32 engine with ACERT Technology. One will meet Tier 4 Final emission standards and will be required for sale in higher regulated countries. The other option will emit equivalent to Tier 2 for lesser or non-regulated countries.

The 6020B meets Tier 4 Final emission standards using:

• Cat NOx Reduction System – captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down temperatures and reduces NOx emissions.

• Dual Diesel Oxidation Catalysts (DOCs) – use a chemical process called oxidation to condition exhaust gases to meet emission standards.

• MEUI™-C Fuel System – delivers increased fuel efficiency, while further reducing NOx emissions. Ultra low sulfur diesel (ULSD) fuel and low ash oil are required.

The Tier 4 Final solution of the C32 ACERT engine has a maintenance free aftertreatment design, which uses the systems above to meet emissions standards. Designed to meet performance demands with lower cost of ownership, the primary advantages of this solution include:

Performance

• Engines optimized for low fuel consumption at 1,800 rpm and lower speeds

• Significant gains in fuel consumption delivered through collaboration of engine and machine integration

• Maximum uptime, without work interruption for regeneration, engine derate, or cold weather treatment of secondary fluid

Lower service times and costs

• Same long life to overhaul, with maintenance-free Diesel Oxidation Catalysts

• No secondary fluid or storage tanks

• No retrofit of current or purchase of new service truck to accommodate storage and delivery of secondary fluid

• No expensive special treatment in cold climate areas due to freezing point of secondary fluid

• Easy access filters
