The object of the invention is a system and a method for moving a platform (1) together with a useful load, for instance a camera or a still camera (22), in space by way of cables (7) or pairs (15) of cables (7) and at least one positioning drum (4) and at least one winding drum (5) arranged on the platform (1), and by way of mounting pulleys (3) arranged on a fixed support structure (2). Such technical solution to moving a platform in space by way of the so-called endless cable allows the system to be more compact, more lightweight, less expensive and simpler to install. The presented technical solution further includes an option that a differential drum (40) is used as a winding drum (5), which differential drum makes it possible to reach the same speed of movement of the platform (1) in all directions without a need to use a more powerful motor for a positioning drum (35) that would otherwise be needed in the case of a transversal movement of the platform along the axis X (12). The system further enables to automatically assess the position of the platform (1) in space by means of the assessment of the position of the attachment points of the platform. |
