Since 1901, ROBEL has been developing, manufacturing and providing track construction machinery with safety and economic benefits. Headquartered in Freilassing, Germany, the company is one of the world's leading manufacturers of railway infrastructure equipment.
The approximately 570 employees at ROBEL's headquarters share a common driving goal — they create powerful machinery and systems for the construction and maintenance of railway infrastructure systems around the world, and deliver them to customers with the best quality services.
ROBEL's equipment is trusted by railway operators across the globe, ranging from light rail and tram systems to high-speed rail networks, ensuring tracks remain safe, reliable, and efficiently maintained.
In 2025, SHBD Precision Parts Ltd. and the German ROBEL Group entered into a joint development project to design and manufacture engine modification components for rail cleaning equipment. The goal was to enhance the performance, reliability, and serviceability of ROBEL's track maintenance machinery.
This project represented a significant milestone in SHBD's growing relationship with European industrial partners, demonstrating our capability to deliver complex co-developed solutions for specialized railway infrastructure equipment.
SHBD's engineering team collaborated remotely and in-person with ROBEL's specialists in Freilassing, Germany to review the existing rail cleaning equipment and define optimal engine modification parameters.
Precision manufacturing of prototype engine modification components at SHBD's facilities, using high-strength steel and aluminum alloys to meet ROBEL's exact specifications for railway duty cycles.
Components were integrated into ROBEL's small equipment systems for track maintenance, with rigorous performance testing to validate reliability, power output, and durability under real operating conditions.
Following successful validation, SHBD scaled to full production and delivered completed engine modification systems to ROBEL, with comprehensive quality documentation and ongoing supply chain support.
The engine modification project required extensive analysis of ROBEL's existing rail cleaning equipment to identify performance optimization opportunities. Key engineering aspects included:
Beyond engine modifications, SHBD and ROBEL jointly developed compact equipment systems designed for efficient track maintenance. These systems featured:
The cross-border collaboration between SHBD (China) and ROBEL (Germany) required a disciplined co-development framework to ensure seamless integration of engineering efforts:
All components underwent rigorous quality assurance and validation procedures to meet ROBEL's stringent requirements for railway infrastructure equipment:
This project marks SHBD's continued expansion into the railway infrastructure sector, building on our core manufacturing capabilities. Key differentiators include:
