On 31 March, the world’s largest-tonnage range-extended rotary drilling rig was officially launched in China, marking the industry’s formal entry into a new era of ‘electrification and commercialisation’. This launch provides a brand-new solution for green infrastructure construction worldwide.
The machine weighs 200 tonnes and delivers a maximum torque of 620 kN·m. Its drilling diameter reaches 3,500 millimetres for extra-large pile foundation projects. The rig provides strong performance in heavy-duty foundation construction applications. Engineers achieved breakthroughs in multi-motor synchronous control technology. The machine improves buffering performance under transient high-load conditions. Its main winch system supports efficient potential energy recovery. The company secured several authorised patents for these core technologies. These innovations highlight rapid progress in new energy construction machinery.

The new rotary drilling rigs feature all-electric, range-extended, and plug-in power modes. The three-mode system supports greener and lower-carbon construction operations. It also maintains high construction efficiency under demanding working conditions. The design reduces the range anxiety common in traditional electric equipment. These rigs suit large-scale bridge and high-speed rail foundation projects. They also perform well in green urban construction environments. The machines handle complex conditions in high-altitude and mountainous regions.
As a new-energy rotary drilling rig gradually enters the mass-production phase, the market is placing ever-higher demands on the stability, durability, and adaptability of high-performance undercarriage systems. As a specialist supplier of undercarriage components for rotary drilling rigs, we will continue to focus on core products such as track rollers, idler wheels, drive wheels, guide wheels, and complete track assemblies, providing our global customers with more reliable and efficient undercarriage solutions, and working together to advance the development of the green construction machinery era.
