Design and core technical characteristics

The TA 300 is an example of an articulated dump truck purpose-built for rough terrain, steep grades and frequent changes in direction. The basic architecture separates the unit into a front tractor (engine and cab) and a rear dump body connected by an articulated joint. This configuration provides superior flexibility and manoeuvrability compared to rigid-frame haul trucks, especially on uneven ground.

Typical specifications (indicative ranges)

• Payload: approximately 30 tonnes (commonly quoted around 28–32 t depending on configuration).
• Gross vehicle weight / operating weight: varies with payload and specification, typically in the 30–60 tonne class when loaded.
• Engine power: commonly in the range of 250–350 kW (330–470 hp) depending on emission standard and tuning.
• Torque: high low-end torque typical of heavy-duty diesel engines to provide pulling force on grades (specific values vary by engine choice).
• Top speed: on flat, firm surfaces typical maximum speed of 30–50 km/h; practical working speeds are lower for safety and control.
• Fuel capacity: often between 300–700 litres depending on package and regional requirements.
• Transmission: robust automatic transmission with torque converter and multiple gear ranges, designed to handle frequent load/unload cycling.
• Dump body capacity: tailored to the payload and material density; bodies are available in different volumes and wear-liner options.

Exact numerical data depend on production year, regional homologation and optional equipment. Manufacturers like Liebherr frequently offer a selection of engines and driveline options to meet local emissions standards (Stage V / Tier 4 Final in many markets) and customer performance needs.

Key structural and mechanical elements
