ABSTRACT:
An apparatus comprising a frame scaffold with a mechanically operated sliding support, as well as methods of assembling, using and disassembling a frame scaffold using the sliding support are disclosed. The apparatus provides for at least one individual to vertically ascend and/or descend along the perimeter of frame scaffold by mechanical operation. The operator of the apparatus is in close proximity to the scaffold. The apparatus does not require the support of an additional structure (i.e., it is self-supporting). The apparatus provides improved safety and efficiency in the assembly and disassembly of frame scaffold.
