Caterpillar is reintroducing a 40-ton model to its articulated dump truck line up. The Cat 740GC incorporates an assorted collection of features also available in the current range of the machines.
Transmission-protection and control functionality, a hoist-assist system as well as an advanced traction-control system, a stability-assist system and a fuel-saving driving mode are all included.
A Cat C15 Acert engine provides up to 337kW (452hp) and powers the three-axle vehicle with a payload capacity of 40 tons.
In addition, the vehicle also incorporates the latest automatic retarder-control system, which requires no input from the operator, resulting in greater operating efficiency. For added control and convenience, a ‘wait-brake’ temporarily applies the service brakes during pauses in the work cycle, reducing operator effort and fatigue.
Optional infrared glass reduces solar heating inside the cab, and left- and right-hand sliding windows increase ventilation, while also facilitating communication with workers and the loader operator.
An automatic climate-control (HVAC) system positions more vents above and behind the operator for increased heating and cooling efficiency. An optional heated/cooled seat provides added adjustments that enable operators to ‘dial in’ personal comfort settings, and the second seat with added cushioning now uses a flip-up/flip-down design to provide additional cab storage.
For added safety, a lighting system, controlled via a ground-level switch, illuminates the cab’s entry steps and hitch area as part of the ‘wake up’ feature, and optional long-range LED work lights improve overall visibility at night.
Optional integrated payload lights provide an external indication of payload levels for the loader operator or site supervisor, helping to ensure proper loading. Exterior features include a redesigned, flexible lower fender and a low-profile exhaust stack that need not be removed for transport.
