发明名称 Ladder support device
摘要 A ladder support device attaches to a towing hitch of a vehicle, such that the ladder can be transported in an essentially horizontal position and deployed in an essentially vertical position. The ladder support device includes safety brackets that limit the range of motion of the extended ladder, a platform that provides a user with secure footing before alighting to and upon descending from the ladder, and a rotatable mount that allows the ladder support device to be moved into the proper work position.
