The tube storage rack is made of stainless stain (to avoid corrosion) and has 4 trays with a storage capacity of 10 CPT sounding tubes each. The lower tray is fixedly mounted, the other three are foldable by means of a hinge-construction (so no handling detachable trays no more).
Up to 16 casing tubes of 1 meter length can be stored conveniently underneath the trays.
A support is provided for easy storage of the first tube assembly (i.e. the first sounding tube with friction reducer and cone) between 2 CPT tests.
