A B S T R A C T Device for a load carrying unit , intended to interconnect theload carrying unit and a supporting member for the load carrying unit , arranged to cause a rotary movement for the load carrying unit in relation to the supporting member in a first plane, and preferably also a pendulous motion in a second plane extending from the first plane. The device includes a tubular or stud shaped member , arranged turnable or rotatable in relation to the supporting member . Said member suspends in the region of an end portion the load carrying unit , and at a distance from same a preferably cylindrical disc shaped member , which defines a first a contact plane with the surface directed towards the load carrying unit . The load carrying unit is arranged with a contact member , defining a second contact surface directed towards the cylindrical member and extending in a substantially parallel relationship. Two groups of bearing means are arranged in an intermediate position between said first and second contact surface, one group being arranged to take up an adjustable contact against the first contact plane, and a second group being arranged to take up an adjustable contact with the second contact plane. A means is arranged to cause a preferably reversible rotary movement for the cylindrical disc shaped member and thus rotate or turn the load carrying unit as desired in relation to the supporting member . The device is advantageously pivotably attached to the supporting member and with at least one piston cylinder , preferably hydraulically operated, arranged to cause a pivoting movement for the device , and thus also thereto attached load carrying unit , in a plane different from the plane in which a rotating or turning movement is performed. The bearing means may be roller shaped, but may alternatively include a substantially flat bearing surface.
