Improvements in and relating to sideless trailers

摘要

A trailer or semi-trailer in which the cant rail (4) supporting the roof is so shaped and arranged as to be capable of functioning as a guide/support for the upper end of a movable support post (2) which extends down from the cant rail (4) across the open side of the trailer or semi-­trailer. This avoids the necessity of support posts (2) when these are not necessary, thus presenting unnecessary intrusion into the load space area.
