Deep in underground coal mines, the soaring diesel costs of traditional fuel-powered transportation equipment are constantly eating into profits; the roar of engines and exhaust fumes have severely deteriorated the underground working environment; and increasingly stringent environmental regulations have brought enormous compliance pressure. High cost, high pollution, and high noise — these long-standing pain points are restricting the high-quality development of mines.
Facing this severe challenge, Nuohao Technology has broken through with innovative technology, launching a full range of pure electric underground auxiliary transport vehicles to reshape the future of mine transportation with green power. We not only provide vehicles but also offer you a complete set of efficient, economical, and environmentally friendly intelligent solutions.
The electrification of the underground coal mine series auxiliary transport vehicles is Nuohao Technology’s core advantage, mainly reflected in two aspects:
Pure Electric Power System: With explosion-proof lithium iron phosphate batteries as the main power source, it boasts a cruising range of up to 100km, achieving zero emissions and significantly improving underground air quality.
Reliable Safety Assurance: All vehicles adopt integral electrophoresis + chassis armor paint, featuring high-performance anti-corrosion coatings and advanced anti-corrosion treatment for the front and rear frames. The vehicle body adopts an integrated molding process, ensuring excellent structural strength.
High Safety | Long Endurance | Strong Load Capacity
It delivers a cruising range of 100 kilometers, fully meeting the demand for continuous operation of more than one shift underground. Equipped with a high-energy-density lithium iron phosphate battery pack, the battery has passed strict explosion-proof certification to ensure absolute safety in the special environment of coal mine shafts. The vehicle supports fast charging technology, enabling energy replenishment during shift intervals to guarantee the continuity of transportation operations.
This design endows the vehicle with excellent passability, with a minimum turning radius significantly superior to that of traditional rigid vehicles, allowing flexible steering and U-turns in narrow underground roadways. Meanwhile, its cargo box is made of high-strength steel, boasting an industry-leading load capacity. It can efficiently transport bulk materials such as coal and gravel, improving overall operational efficiency.
High Safety | Long Endurance | Strong Mobility
Designed specifically as an intelligent mobile operation platform for modern underground mining areas, this vehicle integrates safety, intelligence, and environmental friendliness. With its outstanding performance and reliable quality, it has become the preferred transportation tool for surface operations, equipment maintenance, and leaders' underground inspections in mining areas.
The WLR-5 Series is equipped with a high-performance explosion-proof lithium iron phosphate battery system, delivering a cruising range of 100 kilometers that easily meets the all-weather operation needs of mining areas. Intelligence is another highlight of the WLR-5 Series, featuring exclusive multiple safety guarantees such as P-gear automatic parking and automatic parking protection when doors are opened. It comes standard with reverse radar and front radar, along with a comprehensive collision warning function, taking safety to a higher level.
High Safety | Long Endurance | High Flexibility
The entire vehicle adopts a fully enclosed explosion-proof structure, featuring integral electrophoresis + chassis armor paint, a high-performance anti-corrosion coating, and advanced anti-corrosion treatment for the front and rear frames. High-strength steel, hot-formed steel, and an integrated molding process are used in the body materials to ensure structural rigidity and absolute safety during transportation.
Its optimized chassis design and precise steering system endow the vehicle with excellent passability in narrow roadways. The spacious carriage can accommodate 19 miners in comfortable seating, greatly improving personnel transportation efficiency. It not only eliminates potential safety hazards in underground personnel transportation but also creates a greener and healthier working environment for mines with its environmental protection features of zero emissions and low noise.
