Emissions The reference to Tier 4 Final/Stage IV includes U.S. EPA Tier 4 Final, EU Stage IV, Japan 2014 (Tier 4 Final), as well as Korea Tier 4 Final emission standards.
Note (1) The power ratings apply at rated speed of 1,800 rpm when tested under the conditions for the specified standard.
Note (2) The net power advertised is the power available at the flywheel when the engine is equipped with alternator, air cleaner, muffler and fan at minimum speed.
Note (3) Net power when the fan is at maximum speed is 214 kW (287 hp) per the SAE reference conditions.
Note (4) DEF used in Cat SCR systems must meet the requirements outlined in the International Organization for Standardization (ISO) standard 22241-1. ISO 22241-1 requirements are met by many brands of DEF, including those that carry the AdBlue or API certifications.
Note (1) The operator sound exposure Leq (equivalent sound pressure level) measured according to the work cycle procedures specified in ANSI/SAE J1166 OCT98 is 76 dB(A), for the cab offered by Caterpillar, when properly installed and maintained and tested with the doors and windows closed.
Note (2) Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in noisy environments.

Benefits and Features

Every Tier 4 Final/Stage IV Cat engine with ACERT Technology is equipped with a combination of proven electronic, fuel, air and aftertreatment components. The right technologies fine-tuned for the right applications result in:

  • High machine performance across a variety of applications.
  • Enhanced reliability through commonality and simplicity of design.
  • Maximized uptime and reduced cost with world-class support from the Cat dealer network.
  • Minimized impact of Emission Systems: designed to be transparent to the operator without requiring interaction.
  • Durable designs with long life to overhaul.
  • Delivering better fuel economy with minimized maintenance costs while providing the same great power and response.

The Cat TH31 six-speed forward, single speed reverse transmission features Advanced Productivity Electronic Control Strategy (APECS) and Electronic Clutch Pressure Control (ECPC) which deliver smooth gear changes with improved acceleration and higher productivity.

  • Speed hold/limiting function allows the machine speed to be limited in 1 km/h or 1 mph steps to conform to site speed restrictions.
  • Works in conjunction with the transmission retarder to automatically reduce the retarding level on lesser grades in lower gears.
  • Variable shift points used based on the operating conditions, which also aid in maintaining ground speed during gear changes on grades.

Clutches are also automatically disengaged when not required, eliminating any impact on machine maneuverability, such as making a tight turn at the top of a grade.

The ATC system helps reduce tire and driveline abuse, eliminating lost efficiency caused by improper manual operation of the differential clutches, and reducing the cost of premature tire replacement.

Automatic: The machine carries out “on-the-go” regeneration when the engine control module determines conditions are acceptable. The operator requires no action and the articulated truck is not required to stop working.

Automatic: Low idle regeneration is initiated when the machine is in a reduced operating mode for a predetermined period of time, and a number of conditions are met. The system is designed so that the operator can interrupt regeneration at any time.

Manual: A manual regeneration is initiated by pressing the regeneration switch for five seconds. The machine must be brought to a non-operating mode in order to perform a manual regeneration.

All three axles have oscillating a-frames with lateral tie rods, controlling sideways movement of the axle and providing stability. In conjunction with suspension system, it allows the operator to travel at speed over rough terrain and softens impact loads on structures and components.
