A device for supporting a ladder includes a frame (100) having front leg means (110) at the proximal end thereof, rear leg means (120) and means (8) at the distal end thereof to receive the ladder foot and cradle fixing means (12, 2, 3, 11, 20) between said proximal end thereof and said distal end thereof. A cradle (200) is also included having means (23) for rotatable attachment to opposite sides of said proximal end of said frame (100). Longitudinal cradling means (130) are disposed between said means (23) for rotatable attachment of said cradle (200) and the distal end of said cradle (200) and have means (300) for rotatable attachment of a ladder therebetween near said distal end of said cradle (200). Thus, the ladder can lie along the frame (100), or by pivoting the cradle and inserting it into means (8), be erected, The ladder may be attached to the cradle by an intermediate frame (300). The device may be supported on wheels, and outrigger struts be provided to stabilise the device when the ladder is erected. <IMAGE> |
