Abstract

A method and system for managing an elevator system (10), includes providing at least one elevator car (14) to travel in a hoistway (11), and selectively introducing and removing the at least one elevator car (14) to and from the hoistway (11) via an intermediate transfer station (50) disposed at an intermediate floor location, wherein the intermediate transfer station (50) includes a service lift (54).

First claim

What is claimed is:

1. An elevator system comprising:
at least one elevator car to travel in a hoistway;
an intermediate transfer station disposed at an intermediate floor location to selectively introduce and remove the at least one elevator car to and from the hoistway, wherein the intermediate transfer station includes a service lift, the service lift includes a hoist to engage with the at least one elevator car;
a linear motor system including a primary, fixed portion in the hoistway and a secondary, moving portion mounted to the at least one elevator car, wherein the service lift includes at least one section of linear motor coils to impart motion to the at least one elevator car through the service lift.

2. The elevator system of claim 1 , wherein the intermediate transfer station includes an intermediate parking area.

3. The elevator system of claim 1 , wherein the elevator system includes a plurality of intermediate transfer stations disposed at predetermined locations along the hoistway.

4. The elevator system of claim 1 , wherein the intermediate transfer station is temporarily installed.

5. A method for managing an elevator system, comprising:
providing at least one elevator car to travel in a hoistway; and
selectively introducing and removing the at least one elevator car to and from the hoistway via an intermediate transfer station disposed at an intermediate floor location, wherein the intermediate transfer station includes a service lift; further comprising engaging the at least one elevator car via a hoist of the service lift;
wherein the elevator system includes a linear motor system including a primary, fixed portion in the hoistway and a secondary, moving portion mounted to the at least one elevator car, wherein the service lift includes at least one section of linear motor coils to impart motion to the at least one elevator car through the service lift.

6. The method of claim 5 , further comprising parking the at least one elevator car in an intermediate parking area of the intermediate transfer station.

7. The method of claim 5 , wherein the elevator system includes a plurality of intermediate transfer stations disposed at predetermined locations along the hoistway.

8. The method of claim 5 , wherein the intermediate transfer station is temporarily installed.
