Abstract (en)
An H-shaped modular ladder element (10) which has stringer sections (12A, 12B) which are parallel and spaced apart by a rung or step (14) spanning rigidly between the stringer sections. At their ends, the stringer sections have connection formations (30) by means of which they can be connected end-to-end with other similar modular ladder elements. In this way a ladder of the required length can be assembled. In a preferred form, the connections between elements are achieved by sliding interengagement of ribs and grooves (32, 34).
