Updates for Cat® 740 GC and 745 articulated dump truck bodies

Smart technology, Ease of Use features, and updated cabs are just some of the quality-of-life additions coming to the Cat® 740 GC and 745 dump bodies.

The Cat® 740 GC and 745 dump bodies have recently been updated to increase customer value and performance. The new dump body design reduces carry back in certain customer applications, improves heat distribution in the dump body and provides an impact-resistant inner side plate that extends to the top of the dump body.

Ease of Use features are designed to boost productivity and safety.

The large platform truck continues to retain world class features that continue to deliver value to customers around the world. Cat 745 at 41t and 740 GC offering 36.3t rated payload capacity features a world-class cab design, completely re-engineered from the inside-out using global operator feedback to advance comfort and ease of operation. The external ‘spinal’ ROPS structure boasts bonded rear quarter glass that eliminates the structural pillar to give the operator a dramatic improvement in visibility from the cab. Ground-level switch controls access lights illuminating the steps and hitch area for improved safety when entering the cab. Upon cab entry, the new ‘wake up’ feature initiates machine displays as soon as the door is opened, while the lighter/stronger cab door offers shut assist for improved sealing against dust infiltration. The quieter cab design lowers inside sound levels by 5 dB at the operator’s ear.

Cat articulated trucks also features Cat Detect with Stability Assist. The system audibly and visibly warns the operator if tractor or trailer unit has reached an angle threshold where it is in risk of tipping over. The class leading fully Advanced Automatic Traction Control is improved by technology that will proactively apply the differential locks before any wheel spin. Terrain-based throttle smoothing prevents the new truck from surging when an operator is travelling over extremely rough terrain and is unable to keep steady pressure on the accelerator pedal.

Cat PAYLOAD technology helps operators measure and deliver accurate payloads.

The cab incorporates an infrared glass to reduce solar heating inside the cab, while sliding side windows increase ventilation and allow easier communication with workers on the site. More vents positioned above and behind the operator enable the new automatic climate control (HVAC) system to more efficiently heat and cool the cab. Offering the ability to accommodate a wider range of operators, the heated/cooled seat provides more setting adjustments to dial in personalised operator comfort, while a flip up/down passenger seat offers added comfort cushioning. A ground-level switch controls access lights illuminating the steps and hitch area for improved safety when entering the cab. Cab-mounted mirrors and integrated payload lights offer improved visibility around the truck as well as payload levels for the loader operator.

Ease of Use features

Inside the cab, a combined transmission and hoist lever gives operators efficient single-lever control over truck speed and body hoisting functions to minimise operator effort and automate repetitive operations. At the flick of a switch, operators can choose between manual or fully automatic assisted hoisting control, which automatically applies the Waiting Brake, sets the transmission in neutral and hoists the body to maximum angle at high RPM. A push-button control allows the operator to easily set the machine speed and select transmission hold/waiting brake. Directional gear shifting protection requires bringing the machine to a stop before transitioning from forward to reverse and vice-versa.

The touchscreen display offers intuitive navigation through the screens for simple machine control. The display enables the operator to monitor machine functions and personalise a variety of options. A new emergency stop brake switch next to the display offers a further level of operating safety.

Its powertrain is driven by the Cat ACERT™ engines, which meet US EPA Tier 4 Final/EU Stage IV emissions standards and option lower Tier emissions rating. An economy mode feature results in an average of five per cent fuel consumption improvement in applications where a truck is not required to operate at full productivity.

The improved Cat CX38 High Density Power Shift transmission enhances performance, durability, and productivity, while permanent six-wheel drive enables the truck to navigate even the most challenging terrain. Automatic retarding control manages machine retarding through a combination of engine, brake, gear selection and service brake application without operator intervention. Hill assist facilitates efficient stopping and starting on grades, while the Waiting Brake system, quickly engaged by a push button on the control lever, temporarily applies the service brake during pauses in the work cycle.

In direct response to customer feedback, the lower portion of the front fenders is now made of a durable and flexible rubber sheet material. This change will help decrease maintenance and repair costs on sites where mud packing around the fenders could damage the lower section.

Cat PAYLOAD technology allows operators the ability to measure and deliver accurate payload with the confidence to boost productivity, lower costs and reduce the risk of overload damage. The Cat Productivity system provides customers the ability to optimise operations and improve jobsite efficiency.
