ABSTRACT:
A mobile scaffolding apparatus having wheel support means which can be moved out of engagement with the ground. The wheel support means are mounted to a conventional scaffolding frame made of at least three, preferably four, vertical posts rigidly connected by bracing members. A foot pad is rigidly connected to the lower end of each of the vertical posts. When the wheel support means are moved into engagement with the ground, the mobile scaffolding apparatus rests upon the wheel support means and can travel. When the wheel support means are moved out of engagement with the ground, the mobile scaffolding apparatus rests stationary on the scaffolding frame foot pads. The wheel support means are moved into and out of engagement with the ground through either pivoting or retracting the wheel support means. There are two embodiments for pivoting the wheel support means. In both embodiments, the wheel support means have a wheel and axle assembly, a pivoting rod, and a brace member. One wheel support means assembly is attached to each of the vertical posts. The pivoting rod is pivotally mounted to the vertical post at one end with the wheel and axle assembly rigidly mounted to the opposite end. The brace member is pivotally mounted to the pivoting rod and braces the pivoting rod by engaging the vertical post. In one embodiment, the pivoting rod is held stationary when the brace member is placed in compression between the pivoting rod and the vertical post. In the alternative embodiment, the pivoting rod is braced when the brace member is placed in tension while holding the pivoting rod in a fixed position relative to the vertical post.
The present invention relates to the field of mobile scaffolding mounted on wheel assemblies.
