A quiet revolution is sweeping through China’s—and the world’s—construction machinery industry: the shift to new energy equipment. Once limited to concept models, electrification has now entered full-scale industrial competition. Zoomlion recently rolled out its 5,000th battery pack, XCMG has built a vast portfolio of green products, and LiuGong’s electric wheel loader sales overseas have more than doubled. As leading manufacturers unveil their “electric cards,” the era of green construction machinery has fully arrived.     Beyond “Swapping a Battery”: The Core of Technological Transformation   Battery — The “Super Heart” of Machinery Safety and performance come first. A construction machine’s battery pack must withstand extreme conditions with robust structural strength and advanced thermal management to prevent impact, puncture, or overheating risks. Zoomlion’s milestone 5,000th in-house-developed battery pack reflects not only production capacity but also technological reliability. Delivering high power density under demanding workloads is the key challenge driving innovation in this field.   E-Drive — The Intelligent Muscles of Power Electric motors have replaced traditional diesel engines and hydraulic systems as the primary source of motion. Precision control is essential: for example, when an excavator bucket meets resistance, the system must instantly adjust torque output to avoid damage while maintaining efficiency—an outcome achieved through sophisticated motor control algorithms.   E-Control — The Brain Behind the Power An intelligent electronic control system acts as the “brain” of an electric machine. Like a seasoned operator, it automatically matches the optimal power mode for each condition. XCMG’s self-developed XES Energy Management System intelligently distributes power—similar to a smartphone’s energy-saving mode—maximizing operating efficiency and extending battery life.     Industry Titans Leading the Charge   Zoomlion: A Milestone in Core Component Independence On October 17, 2025, Zoomlion celebrated the rollout of its 5,000th power battery pack in Changsha—a symbol of its fully independent, vertically integrated production chain from core component R&D to green jobsite applications. The pack, featuring a proprietary battery management system, delivers 20% longer cycle life than similar models and remains stable from –40°C to 60°C. Zoomlion also unveiled a full suite of lithium, electric drive, and hydrogen power solutions, demonstrating its all-stack innovation and multi-scenario adaptability.   XCMG: Building a Comprehensive Green Product Matrix Under the theme “Green Power, Smart Future,” XCMG showcased 35 new energy machines and key components at BICES 2025, spanning road, mining, and construction sectors. The company introduced five tailored green solutions for different working conditions. In Inner Mongolia’s Yimin coal mine, for instance, XCMG’s fully electric GR350EP motor grader has entered real-world operation—delivering zero emissions and low energy consumption. Through the dual drivers of electrification and automation, XCMG is evolving from an equipment manufacturer to an integrated solution provider.   LiuGong: Expanding Its Global Electric Footprint LiuGong has taken a pioneering role in the global electrification race. In the first half of 2025, sales of its electric wheel loaders surged 193% year-over-year, representing more than 50% of total electric loader exports from China. Its autonomous electric wheel loaders have also secured over 20 intention orders, pushing commercialization forward. This robust performance has driven LiuGong’s overseas revenue to 8.523 billion yuan—nearly half of its total income.     Real-World Adoption: Where Electrification Leads   Ports and Mines — Economically Driven Transformation Ports and large mines are ideal for electric equipment due to their fixed routes and high-intensity workloads. These sites can easily establish centralized charging infrastructure, maximizing cost savings. LiuGong’s strong overseas sales highlight the financial advantages for energy-intensive operations.   Urban Construction and Special Projects — Regulatory Necessity Urban renewal, subway tunneling, and indoor construction require low-noise, zero-emission operations. Electric excavators and forklifts are often the only viable choice, allowing contractors to work at night without disturbing residents while meeting strict environmental regulations.   Emergency Rescue — Silent but Powerful During earthquakes, fires, or other rescue operations, power outages are common. Electric equipment—powered by large-capacity onboard batteries or mobile chargers—can operate quietly, minimizing noise interference with life detection equipment and gaining precious time during the critical “golden 72 hours.”     Challenges and the Road Ahead   High initial cost: Electric equipment remains more expensive than diesel models, posing barriers for small contractors and rental firms. Limited charging infrastructure: Complex jobsite conditions make fast, stable charging difficult, leading to downtime concerns. Battery recycling: The industry must prepare for large-scale end-of-life battery management in the coming years.   Despite these challenges, the trend is irreversible. As technology advances, production scales up, and green construction policies strengthen, the “tipping point” for electric construction machinery is rapidly approaching. Future job sites will be populated by efficient, clean, and quiet “Green Giants.”     From roaring “fuel beasts” to silent “green titans,” this energy revolution represents more than a power shift—it’s a complete transformation of products, business models, construction methods, and industry ecosystems. Behind it lies the determination of China’s machinery giants not just to follow global trends but to lead the new energy era.   So next time you pass by a quiet construction site, take a closer look—the silent machines at work are shaping the future of Chinese smart manufacturing.

During the scorching summer months, a properly functioning air conditioning system is essential for excavator operators. It not only keeps the cab cool and comfortable but also enhances productivity and safety on site. However, frequent use during high temperatures requires correct operation and regular maintenance to ensure optimal performance and service life.     Key Operating Tips 1. Startup Sequence Always start the engine before switching on the A/C. Turning on the air conditioner after the engine has stabilized helps avoid unnecessary load and protects the compressor from damage.   2. Temperature Setting Adjust the temperature according to actual needs and ambient conditions. Avoid setting it too low, as it increases fuel consumption and engine load.   3. Airflow Mode Select the airflow mode based on comfort and visibility—options include face, foot, or defrost mode. In hot weather, the face-blow mode provides the best cooling effect.   4. Air Circulation Switch In dusty or polluted environments, use recirculation mode to reduce the intake of external air. Switch to fresh-air mode periodically to maintain ventilation and cabin air quality.   5. Avoid Prolonged Idling Continuous A/C operation during idling can lead to increased fuel consumption and engine wear. Minimize use when the machine is stationary for extended periods.   Routine Maintenance Checklist   1. Check Refrigerant Level Observe the sight glass—if only a few bubbles are visible and they decrease with changes in engine speed, the refrigerant level is normal. Low levels reduce cooling efficiency and may damage the compressor due to poor lubrication. Check and refill as necessary.     2. Inspect and Adjust Compressor Belt Tension The compressor is driven by a belt; if it becomes loose or worn, cooling performance will drop. Regularly inspect the belt and adjust the tension as required.     3. Clean and Inspect the Condenser The condenser dissipates heat from the refrigerant. Dust and debris buildup will reduce cooling efficiency. Clean and inspect the condenser fins regularly to prevent blockage.     4. Clean or Replace the Air Filter The A/C filter removes dust and contaminants from the intake air. A clogged filter restricts airflow and lowers cooling capacity. Clean or replace it periodically to maintain optimal performance.     5. Remove Dust and Debris from Radiators Excessive dust on the radiator increases engine temperature and fuel consumption. Keep the radiator and surrounding components clean as part of regular maintenance.
