Abstract
An apparatus or tool for installing an elevator hoist machine to a support at the top of the vertically extending guide rails. The apparatus includes a carriage for imparting vertical movement to move the hoist machine to the upper end of the guide rails and then horizontal movement thereto at the upper ends of the guide rails to enable hoist machines to be installed in areas with limited ceiling height.
Claims10
An apparatus for installing am elevator hoist machine to a machine support affixed at an upper end of a vertically extending guide rail within an elevator hoistway, comprising:
- a carriage for supporting and conveying the hoist machine said carriage being shaped to superpose the hoist machine over the machine support;
- a frame supporting said carriage and being vertically movable along the guide rail, said frame including guide means extending generally horizontally outwardly into the elevator hoistway and terminating in spaced relation from the guide rail, wherein said carriage is selectively horizontally movable on said guide means;
- and
- an attachment means connected to said frame for attaching said frame to a hoist for imparting selective vertical movement of said frame and said carriage along the guide rail to deliver the hoist machine to a position of use whereby said carriage can be moved horizontally to superpose the hoist machine over the machine support and said frame and said carriage can be lowered to position the hoist machine on the machine support.
An apparatus for installing an elevator hoist machine to a machine support affixed to a top of a vertically extending guide rail within an elevator hoistway, comprising:
- an elevator hoist machine carriage including an upper frame for supporting a hoist machine above the machine support;
- a structural frame adapted to be mounted on the guide rail for vertical movement thereon;
- and
- at least one guide shoe slidingly attaching said carriage to said structural frame to enable said carriage to move horizontally toward and away from the guide rail, said upper frame being spaced above said structural frame a distance sufficient to enable entry of the machine support therebetween.
An apparatus for installing an elevator hoist machine to a machine support affixed to a vertically extending guide rail within an elevator hoistway, comprising:
- a frame;
- a first guide shoe attached to said frame for sliding engagement with the vertically extending guide rail permitting said frame to move vertically in the elevator hoistway;
- an elevator hoist machine carriage for supporting the hoist machine;
- and
- a second guide shoe attached to said carriage for sliding engagement with said frame to permit horizontal movement of said carriage on said frame toward and away from the guide rail, said carriage being formed to support the hoist machine above said frame to permit entry of the machine support between the hoist machine and said frame.
