Client Testimonials

Green Transition Gains Momentum: Diesel‑to‑Electric Retrofit Delivers New Impetus for Cost Reduction & Efficiency Improvement — Successful Launch of the First Batch Loader Retrofit Project at Liuzhou Steel Logistics Company
“In the old days, the fuel‑powered loader created deafening noise the moment it started up, consuming nearly 1,000‑yuan worth of fuel per working day. The retrofitted electric version runs almost silently. A full charge delivers 8‑hour operation for just over 100‑yuan of electricity, and handling is even smoother!” A ten‑year‑seasoned on‑site operator spoke highly of his newly‑retrofitted work machine at Liuzhou Steel Logistics Company.
Recently, the technical retrofit project for two loaders at Liuzhou Steel Logistics Company has formally passed acceptance and been put into commercial operation. This marks a solid and critical step taken by Liuzhou Steel Logistics Company in responding to national net‑zero targets and advancing large‑scale equipment renewal and green transition.
These two fuel‑powered loaders with over 8‑year service life have been transformed from high‑fuel‑consumption, high‑emission assets into zero‑emission, low‑energy‑consumption electric workhorses, bringing strong new impetus for cost‑efficiency optimisation and green development of the logistics arm.
Tightening national environmental regulations combined with ageing equipment exposed the fleet of legacy diesel loaders to multiple challenges: excessive fuel consumption, emission exceedances, rising failure rates and persistent high maintenance costs. Each unit incurred annual fuel costs in excess of RMB 180,000 plus maintenance expenditure of RMB 20,000. These costs eroded corporate profit margins. Moreover equipment breakdowns during peak production periods created risks to production continuity and material supply reliability.
Faced with these pain points, the management team of Liuzhou Steel Logistics Company resolved to pursue a green‑development path balancing economic benefits and social responsibility. Guided by the national Action Plan for Continuous Improvement of Air Quality, diesel‑to‑electric retrofit became the preferred technical solution.
This technical transformation is far from a simple powertrain replacement. It represents a comprehensive system‑level upgrade tailored to real‑world operating conditions. To guarantee the retrofitted equipment performs better and offers greater durability than the original units, senior engineering staff spent two‑weeks on‑site collecting and analysing key operational data including workload intensity, ambient temperature‑humidity and material characteristics. A stringent retrofit standard was established: no degradation in performance, enhanced safety protection.
Four core systems underwent thorough technical overhaul: ‑ A 260 kW permanent‑magnet synchronous motor is installed, delivering a 15% power uplift versus the original unit for smoother, jerk‑free operation. ‑ A high‑capacity 360 Ah lithium‑iron‑phosphate battery pack with integrated intelligent thermal management enables minimum 8‑hour stable operation within ‑20℃ ~ 55℃ ambient range, alongside 1‑hour fast‑charge emergency capability. ‑ The in‑house developed vehicle control unit (VCU) real‑time monitors 120 operational parameters and implements three‑level protection including alarm, power derating and emergency shutdown, acting as the “intelligent brain” for equipment safety. ‑ Given the heavy‑dust, high‑humidity and complex conditions at steel‑plant work sites, all core components are upgraded to IP67 ingress‑protection rating. The vehicle chassis is additionally coated with wear‑resistant and anti‑corrosive paint to substantially extend service life.

China’s first pure‑electric locomotive for medium‑and‑long‑haul mainline transport

In February 2026, China’s first pure‑electric locomotive built for medium‑and‑long‑haul mainline transport — also China’s pure‑electric locomotive with the largest‑capacity battery pack to date — was officially put into service on the Shayu Railway in Zhangjiakou, Hebei Province. It undertakes long‑distance coal transport over the 142‑kilometre route.

Featuring innovative three‑electric‑system technology, this new‑energy pure‑electric locomotive is equipped with an ultra‑large 4200 kWh lithium‑iron‑phosphate battery pack. A full fast‑charge takes 1.5 hours, and the battery delivers a cycle life exceeding 4,000 times.

Its kinetic‑energy recovery system achieves up to 75% recovery efficiency. The locomotive handles 2 600‑ton heavy‑haul operations on a 9‰ gradient and maintains stable performance at temperatures as low as ‑20 °C. Furthermore, it is fitted with an intelligent wheel control system to substantially boost operational safety and efficiency.

Following deployment of the battery‑electric locomotive, each unit delivers annual fuel‑cost savings of over CNY 6 million (approx. USD 890,000) and cuts carbon‑dioxide emissions by more than 300 tonnes. Over its full‑life‑cycle, carbon emission reduction reaches approximately 9 000 tonnes. It takes the lead in helping the Shayu Railway achieve its near‑zero‑carbon freight corridor objective and marks the official arrival of the pure‑electric era for China’s heavy‑haul medium‑and‑long‑distance railway transport.
