Caterpillar says its new 745 articulated truck features a next-generation cab design, advanced truck control, and productivity gains with a 45.2-ton payload capacity. The new external “spinal” ROPS structure features rear quarter glass for improved visibility from the cab. 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, and the quieter cab design lowers inside sound levels by 5 dB.
Additional cab features include new infrared glass for reduced solar heating, left- and right-hand sliding windows for better ventilation and external communication, a new automatic climate control (HVAC) system, a new heated/cooled flip up/down passenger seat, a ground-level switch for access lights for the steps and hitch area, and new cab-mounted mirrors and integrated payload lights. Additional features include a new combined transmission and hoist lever, manual or fully automatic assisted hoisting control, a new push-button lever speed control, and directional gear shifting protection to protect the powertrain by bringing the machine safely to a stop when transitioning from forward to reverse and vise-versa.
The machine incorporates the new Cat Detect with Stability Assist system to audibly and visibly warn the operator if tractor or trailer unit has reached an angle threshold where it is in risk of tipping over. The Advanced Automatic Traction Control proactively applies the differential locks prior to any wheel spin. Terrain-based throttle smoothing prevents the new truck from surging when traveling over extremely rough terrain. The new touchscreen display offers intuitive navigation through the screens for simple machine control, enabling the operator to monitor machine functions and personalize a variety of options.
The new articulated truck is said to incorporate all the field-proven features and performance of the C Series for fast cycle times, high productivity, and unmatched fuel efficiency for its class. Its powertrain is driven by the 504-net horsepower Cat C18 ACERT engine, which meets U.S. EPA Tier 4 Final/EU Stage IV emissions standards. A new economy mode offers an average of 5 percent less fuel consumption in applications where a truck is not required to operate at full productivity.
Cat says the truck’s CX38B High Density Power Shift transmission enhances overall performance and productivity, and permanent six-wheel drive enables the truck to navigate challenging terrain. Automatic retarding control is managed 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 push-button Waiting Brake system temporarily applies the service brake during pauses in the work cycle.
In response to customer feedback, the lower portion of the front fender is now made of a durable and flexible rubber sheet material to help decrease maintenance and repair costs. Cat Connect Payload technology allows customers to optimize operations and improve overall jobsite efficiency. The Cat Production Measurement system allows operators to measure and deliver accurate payload.
