LOAD & HAUL
work on, for this kind of vehicle and application, we expect cycle life, as opposed to calendrical ageing, to be the factor that will inform the cost model as these machines are in operation every day. “We have of course designed for
robustness; selecting materials that are more appropriate for the cost and purpose of the vehicle – so more aluminium and less carbon composite. Te most significant shock to the vehicle will be the ~300 tonne load being dropped into the haul bed; so we have run a number of simulations to ratify material and design approach.”
Anglo American has partnered with others to develop a new fuel cell haul truck
JCB has updated its wheeled loading shovel so that it is Stage V-compliant
JCB’s 457 boasts improved fuel economy
Termal management is always an issue when designing new battery systems, and Hoxey is open-minded here. “For the prototype battery system, we do not require liquid cooling; however looking at other usage cases we have designed for this on future iterations. Te battery technology we have selected was in fact
developed for an air-cooled EV. Flexibility is key in the design as Anglo American operates in a number of different environments and the systems need to have the flexibility to optimise for this in a modular fashion.” For regeneration, the capability of the battery system (2MW of peak power,
