Applications, performance and productivity

The TR100 is versatile in application but excels where bulk material handling, short cycle times and reliability are priorities. Fleet planners consider several operational metrics when assessing the TR100 for a site: payload capacity, fuel consumption, cycle time, availability, and total cost of ownership (TCO).

Common applications

• Open-pit mining: Hauling ore and waste from benches to crushers, stockpiles or dumps—often in multi-shift operations.
• Quarrying: Transporting blasted rock to primary crushers or processing plants.
• Infrastructure projects: Mass earthmoving for dams, highways and large excavations where reliable high-capacity trucks speed project delivery.

Performance metrics and typical figures

Performance depends on configuration, terrain and operating practices. The following figures are representative ranges for haul trucks in the TR100’s class and are useful for planning and benchmarking.

• Nominal payload capacity: Around 80–110 metric tonnes (this class is often called the “100-tonne class”; actual rated payload varies by configuration and regional model).
• Engine power range: Typical installed engine power is in the order of 900–1,600 kW (approximately 1,200–2,150 hp), depending on driveline and market specifications.
• Empty and loaded speed: Empty top speeds are commonly in the 50–60 km/h range, with loaded speeds typically limited to 40–50 km/h for safety and braking considerations.
• Fuel consumption: In heavy duty cyclical operation fuel burn can vary widely; typical ranges are roughly 50–120 liters per hour depending on load, terrain, duty cycle and engine tuning.
• Cycle time and productivity: Productivity is directly related to payload, cycle distance and loading efficiency; on short-haul routes the truck can achieve high tonne-km per hour outputs when matched to hydraulic shovels or large wheel loaders.

Operational considerations

To realize the TR100’s potential, operators focus on matching truck size to loader capacity, optimizing haul-road profiles, and implementing effective maintenance and training programs.

• Loader-truck matching: Proper matching minimizes partial loads and reduces cycle time—boosting overall fleet productivity.
• Haul road design: Gradients, bench width and road geometry influence fuel use, tyre wear and cycle time.
• Tyres and wear items: Tyre selection, wheel alignments and body wear liners are high-impact cost items; proper management extends service life and controls operating costs.

Maintenance, safety and lifecycle economics

Long-term value of a haul truck depends as much on maintenance strategy and safety systems as on the original equipment specification. The TR100’s architecture supports modular replacement and in-field servicing—important for remote mining operations.

Maintenance strategies

• Preventive and predictive maintenance: Scheduled inspections plus telematics-based predictive alerts help prevent catastrophic failures and reduce unscheduled downtime.
• Modular components: Swappable modules for powertrain, axles and hydraulic components shorten repair times and simplify logistics for spare parts.
• Workshop and OEM support: Availability of trained technicians and access to genuine parts are essential—especially in remote mining locations where downtime is costly.

Safety features and regulatory compliance

Safety is a core requirement for all modern haul trucks. The TR100 and its class typically include multiple systems to protect personnel and equipment.

• Braking systems: Redundant service and emergency brakes, plus retarders, ensure controlled descent and stopping under load.
• Collision avoidance: Proximity detection, radar, and camera systems are increasingly standard or available as options to reduce runovers and collisions.
