Project Background
In June 2024 , Zhengzhou Railway Equipment Technology Co., Ltd. , a key subsidiary leveraging the technology and market resources of China Railway Construction Corporation (CRCC), partnered with Huaqing to upgrade their maintenance infrastructure.
Zhengzhou Railway Equipment focuses on an integrated “Manufacturing + Overhaul + O&M + Accessories” service model for railway maintenance machinery. To maintain the high safety and durability standards required for rail transport, they implemented the QH26100 complete vehicle shot peening machine specifically for the surface treatment of large-scale railway vehicles.

The Challenge
Railway maintenance machinery operates in harsh environments, requiring frequent overhaul and surface restoration. The client faced several critical challenges:
Complex Integrated Structures: Railway vehicles possess intricate geometries that are difficult to clean uniformly.
High-Volume Maintenance: The “manufacturing + overhaul” model requires high throughput to minimize vehicle downtime.
Strict Adhesion Standards: Surface preparation must be perfect to ensure long-term coating durability on railway equipment.
Our Solution: The QH26100 System


The QH26100 is a flagship “Complete Vehicle” cleaning system engineered for the heavy-duty demands of the railway sector.
Full-Vehicle Coverage: Designed to accommodate entire railway maintenance vehicles in a single cleaning cycle.
High-Efficiency Abrasive Cycle: Optimized for heavy-duty sandblasting and peening to remove rust and old coatings effectively.
Customized Chamber Design: A specialized large-scale booth (as shown in project photos) ensures safe and contained operation for oversized components.
Precision Control: Advanced PLC systems allow for tailored intensity settings, critical for protecting sensitive railway mechanical parts during the overhaul process.
Performance & Impact
The implementation of the QH26100 has significantly enhanced the client’s integrated service capabilities:
Enhanced Surface Quality: Successfully achieves a uniform finish across entire vehicle surfaces, essential for “manufacturing and overhaul” quality control.
Operational Efficiency: Drastically reduced the time required for manual surface preparation of railway machinery.
Industry Standard Alignment: Fully supports the high-level technical requirements of the CRCC resource network.
