Cat redesigns three articulated haul trucks
Cat has updated three of its articulated truck models with a range of new features. The three models – the Cat 730, 730 EJ (ejector) and 735 – have received new operator stations, new controls, transmission-protection, hoist-assist, advanced traction control, stability-assist and a new fuel-saving ECO operating mode.
In addition, the new 730 and 730 EJ have been given automatic retarder control and a hill-start feature. These particular items were already present on the 735’s C-Series predecessor and the updated 735 retains them. All three models are powered by a Cat C13 ACERT diesel, with the 730 and 730 EJ rated at 274kW and the 735 at 319kW.
The new operators’ cab features an external ‘spinal-ROPS’ design that uses a rear-quarter glass panel that eliminates the need for a rear structural pillar, enhancing visibility. Cat says the overall cab design results in a 7dB(A) reduction in noise inside the cab.
The controls inside the cab have also seen a significant upgrade, with a new combined transmission-and-hoist lever that allows singlelever control of vehicle speed and body-hoisting functions. A switch allows operators to choose either manual or assisted hoisting control, with the latter automatically applying the waiting brake, shifting the transmission to neutral and raising the body to its maximum angle at engine high idle.
Another new feature of the updated trucks is Cat’s Advanced Automatic Traction Control system, which can proactively apply differential locks to avoid wheel spin.
The new models also feature a ‘terrain-based’ throttle-smoothing system that prevents acceleration surges when travelling over rough terrain that makes keeping steady pressure on the throttle pedal difficult.
