The WX18H / WX22H LHD stands as the top choice for mines aiming to harness the full potential of today’s hybrid technology. The SR hybrid is meticulously designed to assist in cost reduction, aligning with the goals of zero emissions and electrification in underground hard rock mining.
- Proprietary KESS Technology for Hard Rock: The WX22H hybrid LHD employs Komatsu’s proprietary KESS (Komatsu Energy Storage System) technology tailored for the challenging hard rock environment. This robust system contributes to reduced fuel consumption and lower overall operating costs by minimizing reliance on mechanical components.
- Lower Fuel Consumption – Up to 30% Less Diesel Consumed: Experience significant fuel efficiency with the WX22H, achieving up to 30% less diesel consumption compared to some competitors. This reduction not only supports cost savings but also aligns with environmentally conscious mining practices.
- Reduced Diesel Emissions and Improved Underground Health: By curbing diesel emissions and minimizing heat generation, the WX22H enhances the underground working environment, positively impacting human health. This commitment to reducing emissions underscores the LHD’s contribution to sustainable and safer mining operations.
- Exceptional Acceleration – Up to 20% Increase in Tons Moved: The WX22H delivers exceptional acceleration, potentially leading to a remarkable 20% increase in tons moved. This elevated efficiency enhances productivity and optimizes material handling in underground mining scenarios.
Unleash the power of hybrid technology with the WX18H / WX22H LHD, where cutting-edge features converge to redefine efficiency, sustainability, and performance in hard rock mining operations.
Product Features and benefits:
- Kinetic Energy Storage System (KESS): During propulsion, diesel energy undergoes conversion to electricity. The motors channel energy to the KESS unit for storage. During acceleration, both the diesel engine and the stored KESS energy collectively deliver power equivalent to a combination of a 400 HP engine boosted by another 550 HP engine.
- A Path Toward Electrification: Leveraging KESS hybrid technology, the WX18H LHD exhibits up to 30 percent less fuel consumption compared to diesel machines. This hybrid approach diminishes the reliance on ventilation, facilitating progress toward zero emissions and electrification in mining operations.
- Lower Operating Costs: Reduced fuel consumption translates to enhanced operational efficiency in mine operations. The SR hybrid drive system in WX18H and WX22H LHDs features fewer operating mechanical parts prone to wear and tear. Additionally, costs associated with ventilation needs are diminished.
