Advanced Automatic Traction Control (AATC) proactively applies inter- and cross-axle differential locks ‘on-the-go.’ Operators are freed from this function to concentrate on driving/loading/dumping. Sensors monitor the machine and wheel speeds, enabling instant response in high rolling resistance conditions. Operation is seamless and smooth, eliminating wheel slip for maximum traction and productivity.
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 tire wear.
Automatic Retarder Control (ARC) automates the retarder for the operator. Like AATC, a number of machine operating aspects are monitored. If required, the engine compression brake is engaged automatically to control machine speed when descending a grade. The system can help towards eliminating engine overspeed, improving safe machine operation and reducing cycle times, yet still having the flexibility of manual control if needed.
Ejecting material from the dump body can be automated with the new Assisted Ejecting Control. Flick the new load eject switch and the machine will apply the service brakes, switch the transmission to neutral and push the material out at the required engine RPM. Retracting the blade is done the same way, flick the switch and the machine will fully retract the blade.

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 controlled by large-bore, low-pressure cylinders to assist in a smooth ride. An A-frame with lateral tie rod controls sideways movement and aids stability.
The rear suspension features a walking beam and long-life suspension mounts optimizing ride and load retention.
Fully enclosed wet disc brake systems inside of axles keeps contaminants out extending machine life and ensuring uptime.
Hill assist reduces potential 'roll-back' on grades. If an operator stops the machine on a grade, when taking his foot off the service brake pedal the machine will automatically hold the service brakes on for a number of seconds to prevent the machine from rolling backwards.
Waiting brake applies the service brakes when neutral gear is selected, allowing quick and easy control of the machine at the load or dump area.

The 740 EJ can eject and spread the material while moving, reducing additional spreading and dozing equipment. "On-the-go" ejecting results in faster cycle times and reduced power train loads.
Ejecting the load without raising the body increases stability, allowing unloading on inclines, side slopes and in very soft underfoot conditions especially on landfill sites.
The truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations.
The body design eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.
Reinforced body is made from thick high-yield, heat-treated Brinell hardened steel (Brinell 400 on the base and sides) that provides exceptional durability. Ejector top rails are made from high-strength alloy steel. For optimum durability and wear life, the ejector body is designed to work in applications where the material consists of rocks smaller than 152 mm (6 in) in diameter.
The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.
A four-stage, high-speed, double-acting ejector cylinder is specifically designed for horizontal mounting and smooth load ejection.
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.
The articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain.
Field proven two-piece hitch construction features a durable cast steel head bolted to a hard wearing forged steel tube.
The 740 EJ body has a large target area to provide consistently high load-carrying capacity. Eject blade and body design aid in clean material discharge, maximizing production and avoiding carry-back.
The output transfer gear distributes drive to the tractor and trailer and includes a wet clutch differential lock for optimum traction in poor underfoot conditions.
The full power hydraulic brake system actuates enclosed, oil-immersed, multi-disc, multi-plate brakes with independent front and rear circuits and accumulators. This dual-circuit, all wheel braking system provides the braking performance required to support maximum productivity.
The parking brake is located on the center axle in an elevated position, it is spring applied and hydraulically released.

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.
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.
