Three new articulated truck lines have been "extensively redesigned" by Cat to enhance the performance of their predecessors.

Cat's 730, 730 EJ (Ejector), and 735 articulated trucks have been redesigned with improvements to their respective previous models, the 730C2, the 730C2 EJ, and the 735C.

Among the updates are new operator stations, which include new controls, transmission-protection features, a new hoist-assist system, an advanced traction control system, a new stability-assist system, and the fuel-saving Eco operating mode.

In addition, the design of the 730 and 730 EJ has been enhanced with automatic retarder control and a hill-start feature.

The 735 retains these features from its C-Series predecessor, and incorporates design refinements such as a new Cat C13 ACERT engine,  and structural and dimensional modifications that reduce empty weight by 22%, while retaining the productivity of the outgoing 735C.

Cat's CX31 transmission has been added to the 730 and 730 EJ, as well as the 735. 

As a result of the new features, the 735 is expected to make fuel-efficiency gains of up to 19%.

The following pages outline the key design updates made to Cat's articulated trucks.
