The standard dimensions do not follow the opening dimensions, but have to follow the vehicle dimensions.
The standard dimensions for “cold stores” foresee an internal width of 2400 mm and an outside width of 2800 mm, they are consequently adapt for insulated vans of about 2500-2600 mm external width. In case of narrower vans the dock shelters may need smaller dimensions.
In case of almost uniform height from ground of the van roof, a fixed horizontal cushion dock shelter can be closed. With different roof heights it is necessary to use adjustable top horizontal dock shelter, that are counterbalanced for an easy adjustment.
The dock shelter in made of polyurethane cushions of trapeze shape for the vertical cushions and rectangular shape for the horizontal one. The standard height is of 3000 mm . The cushions are covered by PVC coated polyamide cloth, and the two vertical cushions present overlapped limpets on the fronts, for keeping the vertical frictions of the vehicle during the loading.
