Proven Reliability

  • Cat C9.3B engine offers high power density with a combination of proven and improved electronic, fuel, and air systems.
  • Engine meets China Nonroad Stage III and Brazil MAR-1 emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
  • Thorough component choice, design and in-machine validation processes result in excellent reliability and uptime.
  • Advansys™ GET system features stronger adapters; tips with a new shape to better protect the adapter and an integrated retainer.

Achieve Greater Productivity

  • The proven Cat Z-bar linkage geometry with Performance Series Buckets offer excellent penetration into the pile and high breakout forces. This results in low fuel consumption and exceptional production capabilities.
  • Cat designed, electronically controlled, automatic powershift heavy duty planetary transmission features shift protection and single clutch gear shifting for efficiency, durability, and smooth gear changes.
  • Optional Fusion™ quick-coupler and third hydraulic function can make the machine a versatile tool carrier for buckets, grapples or forks.

Superior Fuel Efficiency

  • Engine Idle Management System (EIMS) reduces idle RPM and fuel consumption.
  • Variable speed fan adjusts to meet the varying cooling requirements of the machine resulting in a reduced average fan speed and lowered fuel consumption, noise levels, and radiator plugging.
  • Load sensing hydraulics produce flow and pressure for the implement system upon demand and only in amounts necessary to perform the needed work functions.

Easy, Comfortable Operator Environment

  • The spacious cab features easy, intuitive controls and excellent visibility which provides a comfortable working environment for efficient operation.
  • A comfortable cloth covered suspension (mechanical) seat is standard, an optional air suspended seat is available.
  • Pilot-operated hydraulic implement controls deliver comfortable, low-effort operation. Two single-axis levers or one joystick are available. Both arrangements are equipped with kick-down switches.
  • Unmatched viewing area with a wide, flat, and distortion-free front windshield.
  • The glass stretches to the floor of the cab for excellent visibility to the bucket and front tires.
  • Sliding side windows on both sides allow natural ventilation and easy communication to ground staff.
  • The cab roof has channels which direct rain off the corners of the cab, keeping windows clear.
  • Air conditioning and heating systems are standard. Ten louvered vents allow the operator to direct the air flow to remain productive and efficient all shift long.
  • Optional windshield guard.

Safety Features

  • Ladders are standard on both sides of the machine; the main cab access features a 15-degree angle to easily access the operator environment.
  • Steps are equipped with hand and/or guardrails to safely access the cab and maintenance points of the machine.
  • The main cab door opens to the front and provides wide access to the operator environment.
  • Front and back wipers ensure that a clear view is maintained.
  • External rearview mirrors with integrated spot mirrors are standard.
  • A rear vision camera is standard to enhance visibility behind the machine.

Reduced Maintenance Time and Costs

  • Grouped service points and sight gauges allow for easy daily maintenance.
  • Convenient access to left, right, and rear of engine compartment provides excellent serviceability.
  • Electrical service center, along with additional key serviceability features, help make servicing and in-field component exchange quick, easy, and efficient.
  • A rear swing-up grill gives easy cleaning access to the cooling cores.
  • Hinged wheel guards are easy to remove/re-install providing wide access to all maintenance points and to the engine compartment.
  • Optional power train bottom guard protects the machine against damage to reduced downtime.
  • Optional Cat Autolube system provides full lube system monitoring and diagnostic test visibility. One-button control, including fault flash function.
  • Caterpillar design and manufacturing techniques assure outstanding service life.

Cat Production Measurement Kit – Optional*

  • On-the-go weighing** for precise load targets with proven accuracy, flexible installation, and easy calibration and setup.
  • Brings payload weighing to the cab so operators can work more productively and deliver consistently accurate loads.
  • Increases productivity, weighing while lifting with no interruptions in loading cycle.
  • High efficiency: load to exact specification, load more trucks faster, and move more material for more revenue.
  • Improve efficiency with less rework; save time, labor, fuel, and costs.
  • Simple installation.
