• A variation on Boalloy's Tautliner with adjustable height roof has enabled Scottish haulier ARR Craib of Dyce to gain access to the restricted British Steel Tubes & Pipes' Corby works.
Boalloy's usual raising roof system can lift by up to 700mm in 100mm increments for running at up to or over 32.5 tonnes.
A spring-loaded blind seals the gap between the roof and door header rails. The Craib trailer is built to 42m overall but this figure can be reduced by 0.65m to 3.55m overall to get into the Corby plant. The height reduction is achieved using an air-overhydraulic ram in the front bulkhead that in turn operates the cable and pulley system to the rear frame.
To assist loading the roof pulls to the front and the rear top rail is swung away.
