ABSTRACT:
An attachable ladder support for use on flat-roofed buildings in conjunction with a ladder and winch. The ladder support has a contact member for contacting the flat roof of a building. Connected to the contact member are two connecting members which are attached to the contact member in such a manner that a hoisting space is created between the two connecting members. Each connecting member is provided with an insertable end for insertion into a tubular ladder rung. When used in conjunction with a ladder and a winch, the ladder support makes it possible to hoist heavy loads up to a flat roof of a building.
