Abstract
A movable scaffolding base for transporting an assembled scaffold along a ground surface comprising a frame, having a front, and a rear, and defining a horizontal plane when the assembled scaffold is attached thereto a drive motor, a steering actuator, a pair of rear wheels attached at the rear and driven by the drive motor to drive the frame, a pair of front wheels attached at the front which are rotated to effect steering by action of the steering actuator, a control system for controlling the drive motor and the steering actuator, a set of scaffold support posts attached to the frame that removably attach to vertical members of the assembled scaffold, and one or more outriggers, extending outwards from a first side of the frame to prevent rotation of the horizontal plane towards the side.
Claims10
A movable scaffolding base for moving a scaffold along a ground surface, the movable scaffolding base comprising:
- a rectangular frame having a front, a rear and two opposing sides with respective front, rear and side members that define a horizontal plane extending along an elongate axis;
- a plurality of support posts extending upwardly from said frame and adapted for removably receiving and supporting corresponding upwardly extending scaffold members;
- a drive motor disposed on said frame;
- a pair of front wheels extending downwardly from said frame proximate to said front for engaging the ground surface and a pair of rear wheels extending downwardly from said frame proximate to said rear for engaging the ground surface, at least one of said pair of front wheels and said pair of rear wheels being driven by said drive motor;
- a control system for controlling said drive motor;
- a plurality of outriggers that are each adapted to slidably and lockably extend outwardly from corresponding outrigger sheaths disposed on at least one of said opposing sides of said frame to engage the ground surface outwardly from said frame and prevent the frame from tipping toward said outriggers;
- a front tip guard connected directly to said front member of said frame forward of said front wheels and a rear tip guard connected directly to said rear member of said frame rearward of said rear wheels, said front tip guard and said rear tip guard each comprising a beam member extending across and generally directly below and parallel to respective said front and said rear members of said frame at a location between said frame and the ground surface so that the respective beam member engages the ground surface if said frame tips beyond a desired point toward said respective front and rear of said frame;
- and
- a front bumper located at said front of said frame forward of said front wheels and said front tip guard and a rear bumper located at said rear of said frame rearward of said rear wheels and said rear tip guard, said front bumper and said rear bumper each extending respectively across said front and said rear of said frame sufficiently to respectively cover said front wheels and said rear wheels,
- wherein said front bumper is mounted directly to said beam member that defines said front tip guard and said rear bumper is mounted directly to said beam member that defines said rear tip guard.
