In the fast-growing construction landscape of Zhejiang, Hangzhou Hongsheng Engineering Construction Co., Ltd. is making headlines with its formidable "steel legion." From the Yiwu Economic Development Zone to Dongyang Expressway, from Hangzhou’s urban arteries to national rail hubs, this elite team—armed with over one hundred of SDLG heavy-duty machines—is reshaping the pace of development across the Yangtze River Delta with China’s smart manufacturing power.

 

Heavy-Duty Backbone of a Super Project

 

At the north square site of Yiwu Railway Station’s elevated terminal, 39 units of SDLG “iron beasts” are delivering a powerful performance. Facing a massive 30 million tons of earthwork, 50-ton+ models like the E6500HB and E6700HB are deployed as the core force. Combined with China Stage IV-compliant models and intelligent construction solutions, this critical East China transport hub is accelerating forward. "During the construction process, the equipment utilization rate can remain above 95%," affirmed Wang Zaigang, the project leader, adding, "Behind this lies the dual guarantee of SDLG's equipment performance and after-sales service."

 

 

A Decade-Long Partnership Built on Trust

 

From roaring China Stage III models to today’s intelligent Stage IV upgrades, Hongsheng’s equipment history reflects SDLG’s evolution. In the west Yiwu earthwork project, 32 units of SDLG machines tore through rock. On Hangzhou’s Wuxiangshan Road, 18 units beat project deadlines. Machines like the E6275H and E6505H brought a mix of power, precision, and performance. “We’ve witnessed SDLG’s transition from raw power to smart solutions,” said the fleet supervisor. “50-70-ton machines now dominate the frontline, and every generation carries forward its technological DNA.”

 

 

Operator-Centric Engineering

 

“SDLG excavators are fuel-efficient, easy to maintain, and extremely comfortable to operate. The brand earns our trust,” shared Operator Zhao, using the E6700HB for precision excavation. This 70-ton beast features an intelligent breaking mode and dual-pump convergence tech, delivering immense force through hard rock.

 

 

As Hongsheng transforms from an earthwork expert to a full-service contractor, its partnership with SDLG continues to evolve.

 

“To me, true integrated solutions must solve today’s tasks while enabling long-term growth,” said Wang. “This project spans 593,200 m² with over 11.77 million m³ of excavation—no small feat. SDLG machines deliver excellent swing speed and loading efficiency, letting us stay months ahead of schedule. Just as importantly, SDLG supports us with on-site engineers available 24/7, creating a 'product + service + value' ecosystem. We look forward to even greener, smarter solutions from SDLG to drive further efficiency.”

 

 

As the city skyline rises and Yiwu Station prepares to welcome its first high-speed train, SDLG’s golden machines stand ready, geared up for the next super project, continuing to fuel the engine of national infrastructure with unstoppable strength.
