To enhance the rolling capacity of haul truck tires, improving fuel efficiency, reducing wear, and optimizing performance, key strategies focus on tire maintenance, operational adjustments, and haul road management. Let’s explore the various strategies.
Optimize tire selection and maintenance
Low rolling resistance (LLR) tires are made with specific tread patterns and rubber compounds that minimise energy loss when driving. However, some LRR tires may sacrifice longevity for efficiency, so weigh tread depth against durability. Underinflated tires raise rolling resistance by increasing deflection and heat. Check and modify pressure on a regular basis in accordance with manufacturer specifications. Consistent rolling performance and longer tyre life are achieved by even wear distribution. Resistance and friction are increased by misalignment or uneven tread wear. Check tires every day for embedded debris, cuts or cracks.
Adjust operational practices
Rolling resistance is increased at higher speeds. On haul routes, lowering speed reduces heat production and energy use. Tire strain from overloading or unequal weight distribution increases resistance. Make sure loads are distributed evenly and within capacity limitations.
Improve haul road conditions
Roads that are rough or uneven increase tyre resistance and deflection. Roughness Defect Score (RDS) can be lowered by up to 66% by treating roads with stabilising agents (such as Dust-A-Side) to minimise imperfections like potholes and corrugations. Wet roads increase the cutting effect of rocks by softening rubber. To keep things dry and less reliant on water, use sealed surfaces. In order to reduce tire abrasion, grade roads often to smooth surfaces and eliminate loose material.
Leverage technology and monitoring
Resistance is decreased by optimal inflation guaranteed by real-time data. To avoid problems, keep track of wear patterns, pressure trends, and maintenance plans.
