A transportation apparatus (1) is disclosed, comprising a payload receiving unit (30), a transportation body (10), and a compensation system (20) arranged there between and devised to allow adjustment of a desired spatial relationship between a payload surface (250) of said compensation unit (20) for attachment of a payload to said a transportation surface (150). The compensation system (20) comprises at least one of a first compensation unit (210) and a second compensation unit (230) arranged for adjustment of said spatial relationship. The first and second compensation units are arranged for adjustment of said spatial relationship in different directions. Thus said compensation system (20) maintains a desired orientation of said payload surface (250) independent of changes of orientation of said transportation surface (150). Further, the compensation system is adapted to substantially maintain a common point of gravity of the transportation apparatus including said payload by displacing a center of gravity of the payload receiving unit and the payload substantially opposite to a displacement of a center of gravity of the transportation apparatus. At least one of said first and/or second compensation units are extendable from at least one end thereof during operation, thus providing a large operational range.Linvention concerne un appareil de transport (1) comprenant: une unité recevant une charge utile (30), un corps de transport (10), et un système de compensation (20) placé entre eux et conçu pour permettre d’ajuster une relation spatiale désirée entre la surface (250) recevant une charge utile dudit système de compensation (20) en vue de fixer la charge utile sur la surface de transport (150). Le système de compensation (20) comprend au moins une première unité de compensation (210) et une deuxième unité de compensation (230) servant à ajuster ladite relation spatiale dans des directions différentes. Le système de compensation (20) maintient ainsi lorientation
