Abstract: A camera support in the form of a camera stand, crane, or camera car has a support column, preferably extending in the vertical direction, for the support of a camera and a leveling head (1) serving to direct the camera in the horizonal direction and being positioned between an adapter (16) located on the upper end (15) of the support column and a camera base (3). The leveling head can be connected to the camera support by a central screw (4). The leveling head (1) is swivel-mounted, relative to the adapter (16) located on the support column end (15), on a vertical swivel axis (12) which is laterally displaced relative to both the adapter axis and the axis of the leveling head to provide easy access to the central screw in the extended position.

Abstract: A camera crane has a two-arm boom supported in swivel fashion by a support olumn whose height can be adjusted. Swivel-mounted to the first arm is a platform for a camera and, if so desired, a seat for a camera-man, and swivel-mounted to the second arm is a cage to receive balance weights. A parallel-guide apparatus provides for the parallel guidance of the platform and the cage when the boom is rotated. In order to provide a greater hoist area, the boom--whose first arm of length "a" supporting the platform in standard operation is longer than the second arm of length "b" supporting the cage in standard operation--is provided with an extension piece of length "c" serving to lengthen the second arm. The cage can be replaced at the end of the second boom arm, lengthened with the extension piece, by the platform, and the cage can be attached in place of the platform at the end of the first boom arm.

Abstract: A telescopically extensible lifting column, particularly for the height adjustment of a camera, consists of an external column member resting on a base plate, a middle column member which is telescopically extensible from the external column member, and a central column which is extensible from the middle column member and on which the camera can be mounted. By means of a piston/cylinder type drive device, the middle column member can be pressurized pneumatically in relation to the stationary external column member. The drive device also has a traction cable which is wound or a deflection member mounted rotatably on the middle column member. The cable is connected by means of its inner end portion to the central column member and by means of its outer end portion to the external column member.

Abstract: A camera truck having a vertical lifting column (9) used for vertical adjustment of the camera comprising an outer column part (10) resting on the chassis, an intermediate column part (11) adapted to be extended telescopically from said outerpart, and a central column part (12) carrying the camera and itself capable of being extended out of the intermediate column part, the column parts having a square cross-section. Wheels (21, 22) used for guiding the column parts relatively to one another are mounted between the column parts and to minimize the spacing between the walls (17, 18) of adjacent column parts, i.e., to allow the use of wheels (21, 22) of relatively large diameter, and to reduce the stresses in the walls in the transverse direction, the wheels (21, 22) are mounted to be rotatable about journals (23, 24) on axes substantially transversely with respect to the outer sides of the column parts, or the central axis of the column.

Abstract: A support wheel device for a camera dolly, comprising four wheel suspension supports (1) each of which is disposed on the frame of the dolly at respective corners of a rectangle and on each of which at least one ground wheel (4) and at least one rail wheel (7) are rotatably mounted and each support is releasably rigidly connectable to a corresponding steering shaft (11) extending perpendicularly to the plane of the rectangle, and the shafts are also connected to a steering mechanism which serves to rotate the four steering shafts (11) in a rotationally synchronous and uniform manner. In order to enable the camera dolly to be run along arbitrarily curved rail paths, as well as on the ground wheels, the invention provides that the wheel suspension support (1) may be coupled to its steering shaft by a disengageable coupling (15, 16), whereby in the disengaged position the rigid connection between the wheel suspension support and the steering shaft is released.
