Yunxin Intelligent Equipment (Chengdu) Co., Ltd., a National High-tech Enterprise specializing in railway maintenance equipment and intelligent solutions, today announced that its self-developed pantograph inspection platform has gained significant market recognition, now serving multiple China Railway bureaus and CRRC Sifang.

The pantograph inspection platform is one of the company‘s flagship products within its urban rail non-standard equipment portfolio-. Designed to support the inspection and maintenance of pantograph systems on electric multiple units (EMUs) and metro vehicles, the platform enables comprehensive inspection procedures including pantograph cleaning, carbon slide wear measurement, insulator inspection, time testing, and static contact force verification.

“Pantographs are critical components mounted on the roof of electric trains that collect power through contact with overhead catenary lines-. Any malfunction can cause significant disruption to rail traffic. Our pantograph inspection platform provides railway operators with a safe, efficient, and standardized solution for routine and preventive maintenance,” said a representative from Yunxin Intelligent.

The platform features a robust steel structure with anti-corrosion treatment and insulation protection measures to ensure operational safety-. It is engineered to accommodate various pantograph types and inspection requirements, supporting daily inspections, routine checks, and monthly overhauls. The design incorporates practical features such as parts storage drawers and tool compartments to streamline the maintenance workflow.

Yunxin Intelligent has established itself as a qualified supplier to numerous major industry players, including China Railway Chengdu Bureau, Xi‘an Bureau, Taiyuan Bureau, Zhengzhou Bureau, Guangzhou Bureau, Urumqi Bureau, Hohhot Bureau, and Wuhan Bureau, as well as CRRC Qingdao Sifang Rolling Stock Research Institute Co., Ltd. and CRRC Qingdao Sifang Locomotive & Rolling Stock Co., Ltd.. The company holds ISO 9001 quality management certification and an AAA corporate credit rating.

The company‘s technical capabilities are backed by a dedicated R&D team comprising 2 senior engineers, 5 engineers, and 10 specialized technicians. In addition to the pantograph inspection platform, Yunxin Intelligent‘s product portfolio includes small-scale railway track maintenance machinery, roof-access platforms for engineering vehicles, driver boarding ladders, various mobile platforms, metro maintenance tooling, railway inspection and analysis instruments, as well as custom steel structure design and installation services.

Looking ahead, Yunxin Intelligent continues to invest in innovation, with ongoing developments in AI-powered inspection solutions and intelligent railway equipment. The company‘s recent patent achievement — a “Electric Multiple Unit Inspection Work Platform” designed to prevent platforms from derailing from tracks — further demonstrates its commitment to advancing railway maintenance technology.

With its proven track record, strong technical expertise, and expanding customer base, Yunxin Intelligent is well-positioned to support the digital transformation and intelligent operation of China‘s railway and rail transit maintenance sector.
