摘要

The platform (1) has a base element (6) comprising four articulated stage elements (7) that are connected together to form a closed contour. Each stage element comprises a gangway (8), and outer and inner crash protection elements. A support member (12) is connected with a carrying rope, and an articulated connection is formed between the base element and the stage elements and designed as a two-member coupled gear. A drive element changes form of the work platform, and the crash protection elements are designed as outer and inner rails (9, 10).
