Curtainsider is the name used to describe a type of trailer common in the UK. This type of truck body or Semi-trailers have flexible sides that can be drawn open like curtains allowing access to the load (cargo) on the trailer, but when shut secure it (in place) and keep the weather off. Useful for palletised loads or larger items that cannot be loaded through the rear doors, but would be damaged on a open trailer. The use of these trailers reduced the need for tarpaulins which are labour intensive & time consuming to fit & remove to sheet a load up for transit & have Health and Safety issues (falls & slips climbing over the load).
