As spring brings new life, a grand occasion unfolds! On the morning of April 7 (local time), the 34th bauma 2025—known as the “Olympics” of the global construction machinery industry—officially opened in Germany with unprecedented scale and excitement.

   

Under the theme “Solid Innovation for Green Tomorrow,” XCMG dazzled the event with its comprehensive “XCMG Solution.” Among the highlights, 13 customized E-series excavators made a powerful debut, showcasing the strength of Chinese manufacturing to customers from around the globe.

   

Quote:“XCMG excavators have proven their efficiency and reliability in the local market. They’re powerful, highly precise, and ideal for urban construction. We trust them completely!”

Quote:“Gut! Super gut machine!”

Quote:“In Europe, XCMG actively responds to the European Green Deal, embracing our corporate responsibility by pursuing zero emissions, low noise, and high energy efficiency,”
said Yang Dongsheng, Party Secretary and Chairman of XCMG Group and XCMG Machinery, during the opening ceremony.

   

• XE10E – “The Smart Artisan” for compact spaces
  
• XE45E – “The Versatile Pro” for urban projects
  
• XE530E – “The Durable Fortress” for mining operations
  

As major infrastructure projects across China accelerate into high gear, the construction machinery industry is experiencing its traditional peak season for both operations and sales. On April 8, CCTV Finance’s Economic News Broadcast aired two feature reports: "Boom in Spring Construction — Domestic Excavator Sales Surge in Q1" and "Full-Capacity Production — Construction Equipment Industry Poised for New Replacement Cycle."

   

The reports, referencing the Excavator Index and providing an in-depth look at SANY Heavy Machinery’s production workshops, vividly depict domestic excavator manufacturers operating at full throttle, busy and fully engaged in production.

At the construction site of the Qianhai International Hub in Shenzhen, Guangdong, dozens of construction machines are operating at full steam. According to the project manager, construction has been accelerating since the start of the year, with continuous increases in equipment investment to seize the prime construction window.

   

Quote:Qiu Wei, Chief Engineer of the Qianhai International Hub project (China State Construction Eighth Engineering Bureau):
“Our project is a large underground transport hub with six basement levels and an excavation depth of over 30 meters. In Q1, we deployed over 40 machines, and we expect to use more than 80 large machines, including excavators, during the next phase.”

Quote:He Pengfei, Head of Operations, SANY Heavy Machinery:
“Even our external suppliers are overwhelmed by demand. Our commercial, procurement, and logistics engineers are now stationed long-term at supplier facilities to push for shipments—they simply can’t keep up.”

Quote:Jia Hailiang, Assembly Center Team Leader, SANY Heavy Machinery:
“We’re racing against time. Orders are not only surging, but they’re also very urgent. Our entire production line is operating at full capacity every single day.”

• In 2023, around 66,100 units were due for replacement.
  
• In 2024, the number rose to 80,600 units.
  
• In 2025, replacements are expected to reach 128,900 units, potentially ushering in a new wave of equipment upgrades across the sector.
  

Quote:Wang Zheng, General Manager, SANY Heavy Machinery:
“This year, driven by various factors—such as replacement demand and national project support—we’re forecasting 15% to 20% growth, slightly more optimistic than last year’s prediction of 10% to 15%.”

At the bauma construction machinery exhibition in Munich, Germany, Cummins unveiled its next-generation 15-liter off-highway engine. The X15 is a future-ready, multi-fuel heavy-duty engine platform capable of running on clean diesel, natural gas, renewable biofuels, or hydrogen—an ideal power solution for customers in construction, agriculture, and industrial sectors looking to improve energy efficiency, reduce emissions, and transition to cleaner energy.

   

• Optimized Design & Simpler Structure:
  Compared to the previous generation, the engine offers higher power density, with outputs ranging from 400 to 700 hp (298 to 522 kW) and a peak torque of up to 3200 Nm, delivering high productivity while replacing larger-displacement engines.
  
• Broader Application Compatibility:
  Over 20 power ratings are available, making it suitable for a wide range of applications.

  Includes robust remote monitoring and diagnostics, OTA (Over-the-Air) software updates, and advanced telematics for high uptime even in remote locations.
  
• Optional Engine Braking Function:
  Reduces axle brake wear and improves vehicle control.
  

• Lower Fuel Consumption & Simplified Maintenance
  The new engine provides up to 10% better fuel economy under comparable operating conditions than the previous generation.
  
• Longer Overhaul Intervals and lower total cost of ownership are further enhanced by digital remote services.
  
• Fuel Flexibility:
  Fully compatible with next-generation biofuels including Hydrotreated Vegetable Oil (HVO) and B20 biodiesel blends, offering customers more energy transition options.
