What is the minimum distance required between the rail and the roof bow insert?

The minimum distance required between the rail and the roof bow insert is critical for ensuring the structural integrity and proper functioning of the dry van trailer. A distance of 150mm allows for adequate clearance to prevent any potential interference or contact between these components during operation and transport. This space also accommodates any necessary thermal expansion or movement of the roofing materials and contributes to the overall stability of the trailer structure.

Having this minimum distance is essential for load distribution and reduces the risk of damage to both the trailer and the cargo it carries. Insufficient clearance can lead to increased stress on the roof bows and rail areas, possibly resulting in structural failures or compromised safety during transportation. Therefore, adhering to the specified 150mm distance is a standard practice to maintain the integrity and longevity of the trailer.
