A portable telescopic hoist has an auxiliary tilt-back frame at the rear for supporting the hoist when it is tilted from its normal upright position to a backward sloped position to clear an overhead restriction. The tilt-back frame has a strut with a gas spring therein having a nearly constant spring force. This strut has a downwardly sloped operating position from a detachable connection at the back of the mast of the hoist.
