The invention relates to a cabin arrangement of the type which is intended to be mounted on a crane post of a crane, comprising a control cabin which delimits an internal space for a crane operator when controlling the crane, a support frame (10) which is adapted to be firmly connected to the crane post, a first linear guide arrangement which is connected to the control cabin and is in displaceable engagement with a matching second linear guide arrangement (16) which is connected to the support frame, and a lifting arrangement comprising a hydraulic cylinder (26) which is telescopically extensible and retractable in such a way that the control cabin is securely connected to the crane post via the support frame while at the same time, by means of the first and second linear guide arrangements and by extension or retraction of the hydraulic cylinder, it is movable along the crane post between a lowered transporting position and a raised working position. It comprises a transport-securing arrangement having at least one first transport-securing element (48), which is connected to and movable together with the control cabin, and at least one second transport-securing element (31), which is connected to the support frame (10), the first and second transport-securing elements being designed to automatically engage with each other when the control cabin reaches its lowered transporting position.
