Breaking New Ground: Tongli Mining Machines Unveils World's First 135-Ton Plug-
November 12,2026
The world's first diesel-electric plug-in hybrid mining excavator, the RE1350H, pushes diesel-electric hybrid excavators straight to the 135-ton class.
A Track Dormant for Over a Decade
Reignited by the "World's First"
Those familiar with the industry know that hybrid excavators are nothing new. More than ten years ago, they were the brightest star direction in the construction machinery industry, with numerous manufacturers rushing in. Yet when the tide receded, the vast majority exited the stage due to immature technology, leaving only Japan's Komatsu holding on alone, with its products stuck at the 20-36 ton class. It was not until China's all-around rise that a new generation of hybrid excavator technology accelerated its landing in China, and Tongli Mining Machines took the lead in achieving a 135-ton-class diesel-electric plug-in hybrid mining excavator.

Why does Tongli Mining Machines dare to make the leap? Because its R&D team has been deeply engaged in mining equipment for over a decade and is recognized as a formidable excavator R&D force in the industry; because today's electric-drive technology, power devices, and intelligent controls are nothing like they were a decade ago; and, more importantly, because Tongli Mining Machines understands that the value of a technological breakthrough is never defined by parameters, but by the mine.
The Scale That Weighs Heaviest in a Miner's Heart
A hundred-ton-class mining excavator operates 5,000 to 7,000 hours a year, and fuel costs often account for more than 40% of operating expenses. To bring fuel consumption down, Tongli Mining Machines developed the industry's most advanced hybrid technology, adopting parallel oil-electric drive and an electric swing system, with two major advantages: engine power "peak shaving and valley filling" and braking energy recovery. This saves fuel while also extending engine life.
Its supporting intelligent control technology is also industry-leading: the AI-R control algorithm intelligently matches the engine with the fully electronically controlled hydraulic system, achieving precise pump-valve control for high efficiency, low consumption, and excellent handling.

Starting from heavy mining duty cycles, through the deep synergy of hybrid technology and intelligent control technology, it recovers the energy once wasted while boosting power. The new-generation plug-in hybrid excavator achieves a comprehensive energy efficiency improvement of more than 15%.
Two Decades, One Full Cycle
This One, the World's First
Around 2004, China's open-pit coal mines were bottlenecked by transport efficiency. Tonli Heavy Industry (Tongli) launched its off-highway wide-body dump truck, and with a single product changed the rules of the entire industry - the development trajectory of China's open-pit coal mines was rewritten from then on.
Now, Tongli Mining Machines, a brand under Tongli, has presented a Chinese solution for hybrid excavators, aiming to rewrite the future of how mines "dig" with the world's first 135-ton hybrid excavator.
What Changes Is the Product, What Stays Is the Plain Creed -
"Only those who understand the mine better can build better machines for the mine."

Tongli Mining Machines will continue to focus on the intelligent, green, and systematized development of mining equipment, using integrated excavation-and-haul solutions as the core approach, and keep deepening its technological innovation.
