Description:

The invention relates to a device for changing the angle of attack of devices, in particular cameras on lifting cranes.

The camera is mounted on a crane platform 7. The camera platform 7 is rotatably connected to the guide connection 2 using the swivel joint 9. The guide connection 1 is movably attached to the crane support 3 using the disk 6.

The guide connection 1 can also optionally be slidably attached to the crane support 3 via the pivot point 10.

The guide connection 1 can also be optionally attached to the structural parts 10 and 11, or be redirected to these structural parts 10 or 11.

The swivel joints 10 and 11 are adjustable in height via the joint position holders 4.

Depending on the position of parts 6 and 9 or 10 and 11, the camera continuously changes the angle of attack when raising and lowering the crane.

The guide connection 1 can be a rigid rod or a flexible rope, or a combination of rod and flexible rope.

Rope adjuster 8 enables length adjustment of structural part 10 in order to trim the camera platform to a specific angle of attack.

Problem:

Changing the angle of attack is necessary when lifting equipment, especially cameras. The angle of attack of the camera near the ground should change evenly when being lifted by the crane in order to ensure the optimal image section.

State of the art

Known devices in this regard have an articulated mounting of the camera platform. The angle of the camera platform is changed by means of a motor drive in order to ensure the optimal image section.

This requires a considerable amount of mechanical, electrical and electronic effort.

Solution:

This problem is solved with the features listed in the protection claim.

Benefits achieved:

This invention enables the operator, in particular the cameraman, to change the camera angle smoothly while raising or lowering the crane using the simplest of means. To do this, he selects a specific trim position of the structural parts 6, or 10, or 9, or 11 before raising or lowering the crane.

The operator is also independent of electric drives, especially in bad weather conditions or in difficult-to-reach terrain (transport problems).

The system is maintenance-free and not susceptible to failure.

Further embodiment of the invention:

Due to the possibility of continuously fixing the structural parts 6 or 10, as well as the structural parts 9 or 11, an infinite number of angle of attack changes can be preselected.

If guide connection 1 and guide connection 2 are set parallel, the angle of attack of the camera remains constant when lifting.
