Abstract:
A construction apparatus is provided and span members connected together at a first end by a first connector, the span members having a first end, a second end and a length. Sill brackets are connected to the first end of the span members and are configured to seat against an entrance sill. A second connector connects the span members together at a second end and is configured to seat against a hoistway structure. A plurality of apertures is arranged on the span members and configured to allow a connection to hoist devices. The span members rotate about the sill brackets and the lengths of the span members are longer than a horizontal distance from the entrance sill to the hoistway structure such that when the apparatus is in a seated orientation, the construction apparatus rests in an inclined orientation with respect to a substantially horizontal axis.
