Abstract

A transportation system for a building with multiple floors includes a shaft, a traction sheave drive type elevator and a lift. The elevator that vertically conveys persons has an elevator car which is movable in the shaft and at least two counterweights which are movable together with the car in the shaft in a direction of movement opposite to the direction of movement of the elevator car. The elevator car and the counterweights are driven by drive engines with traction sheaves. The lift that vertically conveys objects may be a self-propelled lift. A lift platform of the lift overlaps at least partly a vertical projection of the elevator car, whereby preferably the vertical projection of the lift platform is smaller than the vertical projection of the elevator car.

First claim

The invention claimed is:

1. A transportation system for a building with multiple floors, the transportation system comprising:
a shaft;
a traction sheave drive type elevator for vertically conveying persons, the elevator having an elevator car movable in the shaft and at least one counterweight movable together with the elevator car in the shaft in a direction of movement opposite to a direction of movement of the elevator car, the elevator car and the counterweight being driven by a traction sheave drive type including a drive engine with a traction sheave; and
a lift for vertically conveying objects based on a different drive type than the elevator, the different drive type not being a traction sheave drive type, the lift having a lift platform movable in the shaft, wherein the lift platform overlaps at least partly a vertical projection of the elevator car, and wherein a vertical projection of the lift platform is smaller than the vertical projection of the elevator car.

2. The transportation system according to claim 1 wherein a base area occupied by the vertical projection of the lift platform is less than 80% of a base area occupied by the vertical projection of the elevator car.

3. The transportation system according to claim 2 wherein the base area occupied by the vertical projection of the lift platform is less than 60% of the base area occupied by the vertical projection of the elevator car.

4. The transportation system according to claim 1 wherein the shaft has a plurality of elevator shaft doors providing access for passengers into the elevator car, each of the elevator shaft doors being arranged at an associated one of the floors at a front side of the shaft, and wherein the shaft has a plurality of lift shaft doors for providing access for the lift platform or for objects onto the lift platform, each of the lift shaft doors being arranged at an associated one of the floors at a rear side of the shaft opposite to the front side, each of the floors at the rear side being arranged on a same level as a neighboring one of the floors at the front side.

5. The transportation system according to claim 4 wherein the floors associated with the elevator shaft doors at the front side of the shaft include a lowermost floor and the multiple floors associated with the lift shaft doors at a rear side of the shaft include at least one floor that is arranged below the lowermost floor.

6. The transportation system according to claim 1 wherein the elevator car is a front side supported car that is guided along a pair of opposing car guide means, wherein each of the car guide means is arranged at one of two lateral sides of the shaft and in a region adjacent to a front side of the shaft.

7. The transportation system according to claim 6 wherein the elevator includes two opposing counterweights, each of the counterweights being located at one of the lateral sides of the shaft, wherein the counterweights are guided along counterweight guide means, the counterweight guide means and the car guide means on each of the lateral sides being formed by a common guide rail profile.

8. The transportation system according to claim 1 wherein the elevator includes two opposing counterweights, the counterweights being located at opposing laterals sides of the shaft.

9. The transportation system according to claim 1 wherein the lift is a self-propelled lift, the lift platform of the self-propelled lift having at least one climbing drive unit for climbing up and down in the shaft.

10. The transportation system according to claim 9 including at least two lift guiding units arranged in the shaft for guiding movement of the lift platform.

11. The transportation system according to claim 10 wherein the lift platform of the self-propelled lift has at least two motorized gearwheels interacting with the lift guiding units.

12. The transportation system according to claim 11 including four of the lift guiding units and four of the gearwheels, each of the lift guiding units including a vertical post and a roller chain attached to and extending parallel to the post, wherein each of the roller chains receives an associated one of the gearwheels.

13. The transportation system according to claim 12 wherein the posts are formed as hollow rail profiles.

14. The transportation system according to claim 1 wherein the lift platform is a mobile lift platform being a vehicle that can be brought in and out of the shaft and having rolling wheels for movement on the floors.

15. A transportation system for a building with multiple floors, the transportation system comprising:
a shaft;
a traction sheave drive elevator for vertically conveying persons, the elevator having an elevator car movable in the shaft and at least one counterweight movable together with the elevator car in the shaft in a direction of movement opposite to a direction of movement of the elevator car, the elevator car and the counterweight being driven by a drive engine with a traction sheave;
a lift for vertically conveying objects based on a different drive type than the elevator, the lift having a lift platform movable in the shaft, wherein the lift platform overlaps at least partly a vertical projection of the elevator car, and wherein a vertical projection of the lift platform is smaller than the vertical projection of the elevator car; and
wherein the shaft has a plurality of lift shaft doors for providing access for the lift platform or for objects onto the lift platform, each of the lift shaft doors being arranged at an associated one of the floors at a rear side of the shaft, each of the lift shaft doors having an associated controllable lift shaft door drive for reciprocally opening and closing the associated lift shaft door, wherein the lift platform is a mobile lift platform being a vehicle that can be brought in and out of the shaft and having rolling wheels movement on the floors, and wherein the lift shaft door drives are controlled by the mobile lift platform.

16. A transportation system for a building with multiple floors, the transportation system comprising:
a shaft;
a traction sheave drive elevator for vertically conveying persons, the elevator having an elevator car movable in the shaft and at least one counterweight movable together with the elevator car in the shaft in a direction of movement opposite to a direction of movement of the elevator car, the elevator car and the counterweight being driven by a drive engine with a traction sheave;
a lift for vertically conveying objects based on a different drive type than the elevator, the lift having a lift platform movable in the shaft, wherein the lift platform overlaps at least partly a vertical projection of the elevator car, and wherein a vertical projection of the lift platform is smaller than the vertical projection of the elevator car; and
wherein the shaft has a plurality of lift shaft doors for providing access for the lift platform or for objects onto the lift platform, each of the lift shaft doors being arranged at an associated one of the floors at a rear side of the shaft, each of the lift shaft doors having an associated controllable lift shaft door drive for reciprocally opening and closing the associated lift shaft door, wherein the lift platform remains in the shaft, and wherein the lift shaft door drives are controlled by autonomous robots as objects conveyed on the lift platform.
