Up to 6,000kg. Flexible PVC, almost unbreakable. High-quality mobile fridge trailers and freezer trailers (these can chill too). From 2.5 to 4 metres. Refrigerated game trailers, butchery and carcase trailers with hanging rail systems. Overloading small refrigerated trailers can be dangerous as well as causing more repairs and reduced life expectancy for the trailer. Unfortunately, some small refrigerated trailer manufacturers use tires, wheels and axles way too small for the size of the transport box.
