HAUL TRUCK: New Cat 745 has next generation cab, stability assist

PEORIA, Ill. –Offering a 41-tonne rated payload capacity, the new Cat® 745 articulated truck features a world-class cab design, completely re-engineered from the inside out for comfort and ease of operation.

The new Cat 745 is well equipped to climb a muddy ramp.

The new 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. 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.

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. A new combined transmission and hoist lever gives operators efficient single-lever control over truck speed and body hoisting functions to minimize operator effort and automate repetitive operations.

The 745 also features Cat Detect with stability assist. The new 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 prior to any wheel spin. Terrain-based throttle smoothing prevents the 745 truck from surging when an operator is traveling over extremely rough terrain and is unable to keep steady pressure on the accelerator pedal.

The new Cat 745 articulated truck incorporates all the field-proven features and performance of the C Series that 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, which meets U.S. EPA Tier 4 Final/EU Stage IV emissions standards. 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.
