ABSTRACT:
Apparatus for moving construction material relative to a building frame includes a weighted, pivotable base, an extensible shaft projecting from the base, and a carrier assembly adjustable transversely of and pivotable relative to the shaft and including releasable grippers for holding construction material on the assembly, positioned on the shaft. The base has a non-slip exterior surface and a retractable caster housed therein. The shaft is extensible manually and includes a jacking mechanism for extending same incrementally. A spring on the shaft urges the construction material in contact with the building frame. The shaft is made up of telescoped tubular members, and a piston type seal to trap air is provided for dampening downward movement. A collapsible tripod mechanism provides additional support for the apparatus.
