Caterpillar has unveiled the Cat 745 articulated truck, which features a world-class cab design, re-engineered from inside-out using global operator feedback to advance comfort and ease of operation.
The new vehicle offers a 41-tonne rated payload capacity. Its external “spinal” ROPS structure boasts bonded rear quarter glass that eliminates the structural pillar to give the operator an improvement in visibility from 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 five decibels at the operator’s ear.
The 745 also features Cat detect with stability assist. The new system audibly and visibly warns the operator if the tractor or trailer unit has reached an angle threshold where it is in risk of tipping over.
The fully advanced automatic traction control is improved by technology that will proactively apply the differential locks prior to any wheel spin. Terrain-based throttle smoothing prevents the new truck from surging when an operator is traveling over rough terrain and is unable to keep steady pressure on the accelerator pedal.
The cab incorporates new 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 new heated/cooled seat provides more setting adjustments to dial in personalised operator comfort, while a new flip up/down passenger seat offers added comfort cushioning.
A ground-level switch controls new access lights illuminating the steps and hitch area for improved safety when entering the cab. New cab-mounted mirrors and integrated payload lights offer improved visibility around the truck as well as payload levels for the loader operator.
Innovative machine controls
Inside the cab, a new 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 new 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 vise-versa.
The new 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.
Builds on solid C Series design
The new Cat 745 articulated truck incorporates all the field-proven features and performance of the C Series to deliver fast cycle times, high productivity and unmatched fuel efficiency for its class.
Its powertrain is driven by the Cat C18 ACERT engine, rated at 375 kW. A new 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 Cat CX38B high density power shift transmission enhances performance 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 pushbutton 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 Connect Payload technology for the new 745 truck allows customers to optimise operations and improve jobsite efficiency. The available Cat production measurement system gives operators the ability to measure and deliver accurate payload with the confidence to boost productivity, lower costs and reduce the risk of overload damage.
