Yes all trucks do but is it to the same amount as a bendi or flexi. also the one I was working on weighed over 6 ton I assume this is to try and counter balance 1800kg at 90 degrees when the machine turns into the rack to pick or put away. By the by I was told that the rating of a forklift is what ever it is at 500mm or 600mm load centre at eight to ten inches off the ground not always to any height.
