To install the guide rails a rig is lowered by a hoist towards the lower end of the hoistway. An end of a guide rail section is connected to the rig for each guide rail desired. The rig is raised in steps and each step is equal to the length of a guide rail section. At the end of each step an end of an additional guide rail section is connected to the lower end of each row of suspended guide rail sections until the desired guide rail length is achieved. The points of connection of the guide rail sections to the rig are adjusted to locate each row of guide rail sections in the desired position and the rig is blocked in position. The lowest section of each row is next secured to the building structure housing the hoistway and a car frame or sling is mounted on the lowest sections of guide rails. The sling is raised upwardly in steps. At each stop of the sling workmen operating from the sling secure the adjacent parts of the guide rail sections to the building structure and/or install hoistway apparatus on adjacent parts of the hoistway.，下面是Apparatus and method for installing elevator hoistway equipment专利的具体信息内容。
