730 EJ Articulated Truck

730 EJ Articulated Truck

Overview

The Cat 730 EJ with a 16.9 m³ (22.1 yd³)/27.1 tonnes (30 tons) capacity, offers demonstrated reliability and durability, high performance and productivity and a new world-class cab to improve operator comfort and ease of operation.<br>Updating the successful 730C2 EJ to include the new cab design makes the 730 EJ a more attractive proposition for our customers. Class leading levels of performance and new features such as Advanced Automatic Traction Control (AATC) and Assisted Ejecting Control create operator comfort, making a productive machine all day long. The machines retain all axle enclosed wet brakes and Advanced Productivity Electronic Control Strategy (APECS).

MAXIMIZE PERFORMANCE
  • Every Tier 4 Final/Stage IV and EU Stage V Cat engine is equipped with a combination of proven electronic, fuel, air and aftertreatment components.
  • 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.
AUTOMATIC CONTROLS
  • Advanced Automatic Traction Control (AATC) engages inter and cross-axle differential locks on-the-go giving the operator optimum traction as conditions change.
  • Clutches release automatically to avoid conflict during tight turns.
  • AATC reduces tire and driveline wear, eliminating lost efficiency that can occur with improper manual operation.
HEAVY DUTY CONSTRUCTION
  • All three axles promote stability using oscillating a-frames with lateral tie rods. Operate at productive speeds with confidence while virtually eliminating impact loads on truck components.
  • The front suspension oscillates ±6° controlled by large-bore, low-pressure cylinders to assist in a smooth ride.
OPERATOR COMFORT AND CONTROL
  • Spacious cab delivers comfort all shift long and is 4dB quieter than prior model.
  • Unique combination eject/transmission lever is intuitive and enhances cycle times with fewer control movements.
  • Trainer/passenger seat is fully padded with wide, retractable seat belt for security and comfort.
BUILT TO PERFORM
  • Box section front frame absorb is stiff to handle torque loads. Frame design decreases stress at the hitch and optimizes suspension geometry.
  • Rear frame features twin-box construction minimizing stress points and enhancing service life.
  • Front axle suspension provides excellent ride via a three-point oscillating design.
TECHNOLOGY THAT GETS WORK DONE
  • Cat Product Link wirelessly connect you to your equipment, giving you valuable insight into how your machine or fleet is performing. The system tracks location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink user interface so you can make timely, fact-based decisions to maximize efficiency, improve productivity, and lower costs.
BECAUSE UPTIME COUNTS
  • Caterpillar design, manufacturing and customer service help ensure peak performance and uptime.
  • Long service intervals keep your machine operating.
  • Lubrication points are grouped near the hitch for fast, easy routine maintenance.
  • Universal joints are sealed and lubed for long life.
MORE SUSTAINABLE FUTURE
  • Caterpillar designs and functions with great concern for the environment.
  • Cat C13 engine incorporates the Cat Clean Emission Module (CEM) to meet Tier 4 Final/Stage IV emission standards. The system uses both Ultra-low-sulfur diesel (ULSD) fuel or up to B20 bio-diesel blended with ULSD.
BUILT-IN SAFETY FEATURES
  • Seat belt in use indicator (four-point seat belt available as an option)
  • Operator presence detection (prevents gear engagement when operator is not seated)
  • Additional mirror for front of machine visibility
  • Cab mounted, wide angled, folding mirrors

MAXIMIZE PERFORMANCE
  • Every Tier 4 Final/Stage IV and EU Stage V Cat engine is equipped with a combination of proven electronic, fuel, air and aftertreatment components.
  • 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.
  • Delivering better fuel economy with minimized maintenance costs while providing the same great power and response.

  • All Cat engines feature innovative air-management systems that optimize airflow and enhance power, efficiency and reliability.
  • The Cat NOx Reduction System (NRS) captures and cools a small quantity of exhaust gas, then routes it back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.
  • Cat engines equipped with a Selective Catalytic Reduction (SCR) system inject Diesel Exhaust Fluid (DEF) into the exhaust to reduce NOx emissions. DEF is a precisely mixed solution of 32.5 percent high purity chemical grade urea and 67.5 percent de-ionized water.
AUTOMATIC CONTROLS
  • Advanced Automatic Traction Control (AATC) engages inter and cross-axle differential locks on-the-go giving the operator optimum traction as conditions change.
  • Clutches release automatically to avoid conflict during tight turns.
  • AATC reduces tire and driveline wear, eliminating lost efficiency that can occur with improper manual operation.
  • The new ejector body eject/retract switch initiates automated control of machine systems to stop machine travel and eject the loaded material at proper rpm.
  • Hill Assist automatically engages the service brakes if the operator removes his foot from the brake pedal while on a grade reducing potential "roll-back ."
  • The waiting brake system automatically applies the service brakes when the neutral gear is selected, allowing easy control of machine functions at the load or dump area.
HEAVY DUTY CONSTRUCTION
  • All three axles promote stability using oscillating a-frames with lateral tie rods. Operate at productive speeds with confidence while virtually eliminating impact loads on truck components.
  • The front suspension oscillates ±6° controlled by large-bore, low-pressure cylinders to assist in a smooth ride.
  • The rear suspension features a walking beam and long-life suspension mounts optimizing ride and load retention.
  • New fully enclosed wet disc brake systems inside of axles keeps contaminants out extending machine life and ensuring uptime.
OPERATOR COMFORT AND CONTROL

  • Unique combination eject/transmission lever is intuitive and enhances cycle times with fewer control movements.
  • Trainer/passenger seat is fully padded with wide, retractable seat belt for security and comfort.
  • New large side storage box is heated/cooled by the HVAC system.
  • Air-suspension seat offers greater comfort, with a greater range of adjustments. Fore/aft isolation dramatically reduces vibrations and jolts. Every operator will find a adjustments to ensure comfort and control all shift long.
  • Standard cooling/heating system ensures comfort in all conditions.
  • Optional four-point seat belt is available to help operator stay in position and comfortable in rugged terrain.

The system tracks location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink user interface so you can make timely, fact-based decisions to maximize efficiency, improve productivity, and lower costs.
  • Cat Production Measurement brings payload weighing to the cab to help optimize job site efficiency and productivity. Operators can view real-time load weights on the integrated display and know precisely when target is achieved, while cab-mounted external payload lights on all four corners signal the loader operator when to stop, reducing the risk of machine overloading. Operators can track daily productivity from the cab, with quick access to truck payload weights, loads and cycle counts, and daily totals; or remotely via LINK technologies.
  • Cat Detect with Stability Assist warns the operator if machine is approaching a pre-set angle during operation; when driving and tipping. If using the assisted hoist, the machine will stop hoisting the body and give an audible and visual warning. The system monitors angles of tractor, trailer and grade independently. This increases operator awareness of machine stability during operation. All tractor and/or trailer rollover events are logged and reported via VisionLink.
