Title: (EN) Flexible ladder for use on moving conveyances
Abstract:
(EN) A flexible ladder for use on moving conveyances which provides frontal stability but lateral flexibility, the ladder having a first (40), a second (42) and a third (44) strut member each formed of flexible material and each supported in a generally vertical plane, the strut members being parallel to each other with the second strut member between the first and third strut members. A first set of steps (46) are secured between the first and second strut members and a second set of steps (40, 50) are secured between the second and third strut members, the steps being vertically spaced apart from each other and the upper ends of each of the strut members being affixed to a moving conveyance, the ladder providing for ascent of an operator to the operating position on the conveyance but permitting lateral flexibility if the ladder engages an obstruction on the surface on which the machine moves.
