Drive Systems

Meeting Your Site Specific Needs with a Choice of Robust Drive System Options

Giving you the option to choose the drive system best suited for your operation, the Cat 6018/6018 FS can be equipped with either two Cat C18 diesel engines for greater mobility, or an electric drive for better efficiency.

  • Reliable Cat C18 ACERT Engine
    Delivering durable, reliable power that will keep your primary loading tool producing, the C18 has proven its ability to stand-up to the harshest mining conditions, providing the mobility and flexibility you need. In addition, they’re backed by our world-class dealer network, ready to provide service and support when needed.
  • Efficient Electric Drive System on 6018 AC/6018 AC FS
    Providing a lower cost-per-ton alternative to diesel powered hydraulic shovels, our electric drive option maintains the ruggedness you need and offers superior availability since no refueling and less service is required.

    This solution is ideal for operations that do not require a great deal of mobility and value a low cost-per-ton model.

Twin-engine Concept

Keep Producing and Ensure the Safety of Your Operators, Even During Single Engine Loss

You will realize enhanced safety, greater uptime, more productivity, and better serviceability as a result of our twin-engine concept.

  • Enhanced Safety
    The ability to move your shovel to a safe area for repair, away from high walls, blast zones, or other safety hazards, is still possible with the use of a single engine.
  • Greater Uptime and More Productivity
    Up to 65% of full production can still be achieved with the use of a single engine. This is due to the shovel’s continued ability to exert maximum digging forces, to lower the front attachment without requiring engine power (i.e., pressure-free), and to recuperate energy via its closed-loop swing circuit.
  • Better Serviceability
    Troubleshooting is greatly simplified and expedited with the ability to compare one engine versus the other.

TriPower System (Front Shovel Machines)

Dig More Effectively with Our Unique TriPower Front Shovel Design

You will experience enhanced, easier and faster front shovel operation with TriPower, a system proven on over a thousand Cat hydraulic shovels worldwide. Generating superior mechanical leverage and control, our FS configured hydraulic shovels utilize a unique boom design that employs rotatable triangular rockers. This design facilitates quicker cycle times, increased effective lifting force, constant boom momentum, automatic constant bucket angle, and automatic roll-back limiter.

  • Quicker Cycle Times
    Faster lifting speeds are achieved, because the design enables the use of smaller-diameter boom cylinders.
  • Increased Effective Lifting Force
    Design transfers digging forces into the superstructure, creating supporting boom momentum in addition to momentum that is generated hydraulically.
  • Constant Boom Momentum
    - Allows smaller boom cylinders for higher lifting speed.
    - Keeps lifting speed constant. –Enables the shovel to lift a single load along the entire digging distance.
    - No retracting of stick cylinders is required, ensuring that all hydraulic pumps are supplying the boom-up function.
  • Automatic Constant Bucket Angle
    - Material spillage is avoided during boom lifting, because the filled bucket automatically maintains a constant bucket angle.
    - On conventional kinematics the operator has to control manually the bucket position during lifting which cut in half the available oil flow for the boom cylinders.
  • Automatic Roll-back Limiter
    - Preventing material spillage back on to the operator’s cab and machine superstructure, our system ensures that the bucket is always in a safe position, without operator control/manipulation, when it is at maximum height.
    - The boom cylinder continues to receive maximum oil flow, because the operator does not need to activate the bucket cylinder.

Hydraulic System

Straightforward, Safe System Maintenance

Ensuring neat organization for safe operation, easy inspection, and fast service, and reducing the number of hoses needed, the main valve block is located on top of the boom.

Faster Cycle Times

Faster cycle times are realized, because float valves are used to lower the boom instead of engaging pumps. This facilitates faster boom movements and allows other operating functions to occur simultaneously, such as bucket curl and stick in/out.

Independent Oil Cooling System

Protect and Extend the Life of Your Hydraulic Components and Seals

Providing a more 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 our electronically controlled radiator fan speed. The fans do not run until oil temperature exceeds a temperature of 50° C (122° F), saving energy.

Optimal Oil Temperature Maintained

The high-efficient oil cooling system ensures that the oil temperature is only 25° to 30° C (45° to 54° F) higher than the ambient temperature. Thus the hydraulic oil working temperature ranges within the optimal operating viscosity range of 50° to 70° C (122° to 158° F).

Pump Managing System

Experience Improved Machine Control and Component Life, while Reducing Fuel Consumption and Noise Emission, with Our Intelligent Pump Managing System

Delivering optimal performance, our pump managing system continuously evaluates actual engine and hydraulic operating values against set values, and adjusts pump output accordingly. This results in efficient use of the engine for greater productivity.

Pump managing system advantages include:

  • Best possible utilization of engine output and engine overload avoidance via electronic load limit regulation.
  • Less energy consumption and less thermal load on hydraulic oil with zero oil flow regulation for main pumps.
  • Less fuel consumption and lower noise emission via automatic RPM reduction.
  • Reduced component wear and lower noise emission with automatic oil flow reduction for closing/opening of bucket clam.
  • Protection of components with automatic oil flow reduction if hydraulic and/or engine coolant temperature exceed set maximum.
  • Improved operator control response via on-demand pump flow.

Closed-loop Swing Circuit

Load More Material, at Lower Cost, with the Energy Recovery Capability of Our Closed-loop Swing System

Delivering faster cycle times and improved energy efficiency, while also generating less heat, our closed-loop swing circuit provides distinct advantages over competitive machines utilizing open-circuit swing systems.

Greater Efficiency via Energy Recovery

Kinetic energy captured during the swing motion is fed back into the system during deceleration, providing more power to drive the main and auxiliary pumps. Energy is saved during deceleration, because braking occurs via counteracting controls, as opposed to throttles used in open circuit swing systems.

Energy Savings During Acceleration

Energy is saved during acceleration via torque control, providing a pressure balance valve that controls the swing pump against pressure in the closed-loop swing circuit, ensuring that only the minimum necessary oil flow is utilized at any given time.

Faster Cycle Times

Faster boom lift motion during swing is achieved with our closed-loop swing system, increasing overall productivity.
