Abstract (en)

A ladder assembly (1) having a telescopic ladder (10) of lightweight tubular construction mounted on a trailer chassis (2). The ladder (10) has a bottom ladder section (12) pivotally mounted at one end of the chassis (2) for movement between a raised in-use position and a stored position against the chassis (2). A counter-weight (19) is attached at a lower end (18) of the bottom ladder section (12) to assist pivoting. A top ladder section (13) is slidable on the bottom ladder section (12). The top ladder section (13) has a pair of spaced-apart ladder sides (30) interconnected by rungs (32). A hollow anti-torsion bar (38), preferably of box-section, interconnects the rungs (32) substantially centrally located between the sides (30). A strut framework (50) pivotally connected at an upper end of the bottom ladder section (12) is engagable with strut receivers (56) at a front end of the chassis (2) to support the bottom ladder section (12) in the raised position. A bracing member (70) extends between the strut framework (50) and the bottom ladder section (13) to resist bending of the bottom ladder section (12) in use. <IMAGE>
