The Most Advanced Traction Control SystemLearn More
Automatic Traction Control (ATC)
Fully Automatic Traction Control (ATC), with Inter-Axle-Differential lock (IAD) and Cross-Axle-Differential locks (XAD) feature oil immersed clutches that require no operator input. Operation is seamless and smooth, eliminating wheel slip for maximum traction. Sensors monitor the machine and wheel speeds, enabling instant response in low traction conditions. Fully automatic, independent, IAD and XAD clutches are engaged on-the-go to optimize machine performance and control in all conditions. Clutches are automatically disengaged when ground conditions dictate, maximizing efficiency when steering or on uneven ground. Clutches are engaged proportionally, from 0% to 100%, as ground conditions dictate. ATC eliminates wheel spin in soft underfoot ground conditions or on slippery grades. It also reduces tire and driveline abuse caused by improper manual operation of the differential clutches. The ATC allows ‘true’ 6×6 drive with proportionally open differentials for best power efficiency.

Disperse Loads on-the-go for Faster Cycles and Lower Spreading CostsLearn More
The ejector body offers clean load ejection and the capability to work in areas with restricted overhead clearance and soft underfoot conditions.
The 730C EJ shares the versatility of the Standard 730C Articulated Truck, operating in the same conditions but offering unique capabilities that stretch the operation envelope.
The truck can eject and spread the material while moving, reducing additional spreading and dozing equipment. On‑the-go ejecting results in faster cycle times and reduced power train loads.
Ejecting the load without raising the body increases stability, allowing load dispersal on inclines, side slopes and in very soft underfoot conditions especially on landfill sites.
The truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations.
The body design eliminates material sticking to the body, which increases productivity, improves fuel efficiency and lowers cost per ton.
The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.
A three-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and smooth load ejection.
