Transformer on tour

2,000 kilometers on 20 axles – 450 tons rolling across China

How to get a huge transformer for a new power station to cover a 2,000 kilometer distance? The Militzer & Münch team in China had the solution: on a 20-axle bridge trailer.

The order for the heavy lift transport came from the Chinese electric utility company. Militzer & Münch organized the complete door-to-door transport from the manufacturer’s plant in Boading, northern China, to the construction site in Tianshui. At 450 tons, the transformer was too heavy for a standard low platform trailer; on the axles of the bridge framework trailer, the weight was evenly distributed.

Precise preparation


To make sure the roads can bear the high strain, the team did a preliminary road survey for the entire distance. Only then were they able to apply for a special authorization to use the roads. Militzer & Münch had to obtain a special permit from each of the four provinces the transport crossed – Hebei, Neimenggu, Ningxia and Gansu.

In order not to overly hinder traffic, a large part of the distance was covered by night. The bridge trailer covered the 2,000 kilometers in 15 days. An escort vehicle accompanied the transport from start to destination.

The bridge trailer with 20 axles covered the 2,000 kilometers through four Chinese provinces.
