Folding crossbar for launch ladders and multi-part ladders

摘要

Folding traverse (4) for stabilizing a ladder (1), with two elongated truss legs (65, 66), which are each received longitudinally displaceably in a pivotable receiving profile (7, 8) at the end of a spar (2) of the ladder (1), and in the space between the bars (2, 2) in their end-side connecting region pivot bearings, wherein the crossbar legs (65, 66) in their end connection area via a common, ladder-free pivot point (9) are interconnected, characterized in that the truss leg ( 65, 66) is formed in two parts and consists of a respective cross-member profile (60, 61) and a truss joint (5, 6) received therein and in that a stop (33) is mounted on the upper edge of each cross-link (5, 6) in the unfolded state of the traverse (4) hangs on a contact area (47) of the other crossbar joint (5, 6).
