ABSTRACT:
A guide rail section is pushed up a hoistway through a guide funnel by a hydraulic lift pad. The guide funnel is detachably mounted to a wall bracket. The guide rail section is retained in the hoistway while the lift pad is lowered. Another guide rail section is positioned on the lift pad and aligned with the guide rail section retained in the hoistway. The aligned guide rail sections are connected by a fishplate. The guide rail section retained in the hoistway is released and the lift pad is raised pushing the connected guide rail sections up the hoistway through guide funnels. The procedure is repeated until a stack of guide rail sections of the appropriate length is assembled.
