At bauma China 2024 not too long ago held in Shanghai from November 26-29, XCMG unveiled model 2.0 of its 85 t class cabless, autonomous and electrical mining truck, generally known as the ZNK95, throughout a particular ceremony with coal mining buyer Huaneng Group. Model 1.o of the ZNK95 was launched in 2023, following the launch of the 70 t capability XDR80TE-AT. On the present, the brand new truck was proven being loaded by one other progressive machine – the XE1600H, claimed by XCMG because the world’s largest hybrid mining excavator.
The Yimin (typically referred to as Yiminhe) open-pit coal mine of Huaneng Group in Internal-Mongolia, China, is the first buyer to this point for the ZNK95 and has been operating a small fleet of ten vehicles for a while. XCMG estimates that the mine will scale back 47,000 t of diesel consumption and 149,000 t of carbon emissions after scaling as much as 300 items by 2026.
The ZNK95 Clever Mining Dump Truck to offer it its full identify is the biggest electrical autonomous mining dump truck presently accessible and one of many pioneering new power autonomous mining vehicles within the trade. That includes a cabless design, XCMG says it’s absolutely able to working in high-altitude, extraordinarily chilly environments all the way down to -40°C. The automobile is provided with a devoted everlasting magnet synchronous electrical drive system for mining, assembly the heavy load and steep gradient necessities of mining vehicles. This utilises a excessive torque direct-drive motor + twin high-speed motor energy meeting. Its battery capability is 509 kWh with peak energy of 800 kW and most peak torque of 22,000 Nm.
XCMG provides that the ZNK95 innovatively utilises automobile, cloud, and community collaborative expertise to seamlessly change between short-distance distant management, long-distance distant operation, and autonomous clever driving modes. The autonomous driving system integrates a number of cutting-edge applied sciences, providing capabilities equivalent to environmental notion, decision-making and planning, automobile management, fault analysis, and automobile communication. It’s able to complete mining operations throughout totally different machine varieties, with single-vehicle transport effectivity surpassing that of handbook driving.
It could actually change freely between three modes: brief distance distant management, distant management, and unmanned sensible driving. Customisation of varied battery-swapping modes is feasible equivalent to unmanned battery swapping stations and cell battery swapping. It utilises multi-channel RTK cm stage real-time positioning utilizing BDS, GPS, GLONASS, and so on.
The XE1600H hybrid hydraulic excavator is provided with a normal 10 m³ rock bucket, providing excessive mining excavation and loading effectivity with low gasoline consumption. It’s powered by a Cummins QSK19 engine with an built-in vary extender motor additionally serving as an influence supply, permitting the engine, motor, and hydraulic pump to function on the similar velocity, reaching ‘peak load shifting.’
XCMG’s self-developed high-flow electronically managed important hydraulic valve gives superior efficiency, versatile management, and the flexibility to exactly handle varied operations. It could actually alter circulation and strain in response to the system’s precise load necessities, optimising load matching and lowering overflow losses, leading to larger power effectivity. Moreover, the usage of a increase regeneration valve successfully harnesses the increase’s descent potential power, additional enhancing power financial savings.
