Telescopic jib

摘要

The support block (11) is erected using an arrangement comprising a tensile anchor (17) connecting the block to an inner telescopic part (6). The block is pivotally mounted on an outer telescopic part (5) housing this inner part. Telescopic parts (5-8) can be extended from a pivoting connection part (2) for the jib (1). A brace (9) for the jib is formed by at least one support block pivotally connected to one or more of the telescopic parts, at least one cable (10) supported by the block and an erection device for moving the block from a folded away transport position into an upright working position.
