Benefits and Features

Offering both automatic and manual options, the system gives operators flexibility to choose their preferred method of control. When using the automatic system to eject a load statically, the machine neutralizes the transmission, applies the service brakes and ejects the blade at the required engine rpm. On-the-go ejection can be controlled by the operator to spread material as required. Automatic use can reduce operator interactions by up to 50 percent depending on the site ejecting procedure.

Waiting brake, transmission hold and machine speed limiter functions are easily accessed using the buttons on the lever. The park brake has also been incorporated giving operation a more automotive feel. No separate switch is now needed; you just push the lever into park.

This provides a greater number of operators with the ability to tailor their seating position for a more comfortable working day. The seat can be selected with variable climate control as an option.

A reduction to in-cab noise (–7 dB from previous model) contributes to a more comfortable working environment for the operator, all day, every day.

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:

  • All new Eco mode, which can provide an average reduction in fuel consumption of 5 percent over normal operation.
  • High machine performance across all 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 operate 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.

DEF is a precisely mixed solution of 32.5 percent high purity chemical grade urea and 67.5 percent de-ionized water.

The Cat High Density Power Shift (HDPS) nine-speed forward two-speed reverse transmission, designed specifically for Articulated Trucks, features Advanced Productivity Electronic Control Strategy (APECS) and Electronic Clutch Pressure Control (ECPC) that 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.

Gearshifts are configured to maintain direct drive lock-up, and reduce dropping into converter drive. Decreasing the use of torque converter drive aids in maintaining ground speed and gradeability.

Variable gearshift points are used based on the operating conditions, which also aid in maintaining ground speed during gear changes on grades.

Clutches are automatically disengaged when ground conditions allow, maximizing efficiency when steering or when on uneven ground.

AATC reduces tire and driveline abuse, eliminating lost machine efficiencies caused by improper manual operation of the differential clutches, and reducing the cost of premature tire replacement.

The 740 EJ shares the versatility of the 745, operating in the same conditions, but offering unique capabilities that stretch the operation envelope.

The introduction of the new combined eject/transmission lever gives you the option to auto eject, as well as full manual control.
