Abstract

The sections of the telescopic main jib-arm are moved in and out by a telescopic cylinder linked to the outer jib-arm section. The tiltable auxiliary jib-arm possessing an end-piece has at least one or more interconnectable lattice mast elements, and is positioned on the main jib-arm. An angled lattice point (11) is positioned on the top (9) of the tiltable auxiliary jib-arm element (16) by means of an intermediate piece (10) setting the angle towards the main jib arm (1). The intermediate piece has at least one connecting rod and piston-cylinder unit.
