About the Caterpillar 730C2 Ejector Truck (2L8, 2T5)

The Caterpillar 730C2 Ejector is a 31-ton hauler engineered for maximum versatility and safety in applications where traditional tipping is not possible, such as tunneling, working under overhead power lines, or on soft, unstable terrain. Featuring a robust 6x6 drivetrain and an advanced industrial diesel engine, the 730C2 EJ utilizes a high-force hydraulic ejector blade to unload materials while on the move. This allows for a clean spread of material and eliminates the risk of tipping associated with traditional dump trucks.

The 730C2 series brings enhanced durability and performance, incorporating the Advanced Productivity Electronic Control Strategy (APECS) for smoother shifting and better acceleration. Maintaining these sophisticated systems requires the precise factory specifications found in this manual to ensure long-term reliability and lower operating costs. Investing in this digital guide protects your machinery investment and ensures reliable, long-term operation in challenging conditions.
