## Abstract

A platform for a wind turbine, the platform including a lift beam for carrying a load of a transport cabin of a tower lift of the wind turbine is provided. By the lift beam being part of the platform, an easier installation of the platform and the lift beam is possible. Furthermore, less components are needed. Another advantage is that the lift beam is installed at a smaller height of the tower where the tower has a larger diameter compared to a conventional lift beam. This increases the available space for lift cables hanging from the lift beam.

## Claims

### Claim 1

A platform for a wind turbine, the platform comprising:
a lift beam for carrying a load of a transport cabin of a tower lift of the wind turbine.

### Claim 2 (depends on 1)

The platform according to claim 1, comprising a bearing structure and a floor plate supported by the bearing structure, wherein the bearing structure comprises the lift beam.

### Claim 3 (depends on 2)

The platform according to claim 2, wherein the lift beam is integrally formed with the bearing structure.

### Claim 4 (depends on 2)

The platform according to claim 2, wherein the floor plate is arranged above the bearing structure having the lift beam, and the floor plate is fixed to the lift beam.

### Claim 5 (depends on 1)

The platform according to claim 1, comprising attachment means connected to the lift beam and configured for attaching one or more cables of the tower lift to the lift beam.

### Claim 6 (depends on 5)

The platform according to claim 5, wherein the attachment means protrudes above the floor plate.

### Claim 7 (depends on 1)

The platform according to claim 1, wherein the lift beam comprises one or more openings for passage of one or more cables of the tower lift.

### Claim 8 (depends on 5)

The platform according to claim 5, wherein the attachment means includes one or more brackets and one or more pins supported by the one or more brackets, each pin of the one or more pins being configured for connection with one of the one or more cables of the tower lift.

### Claim 9 (depends on 1)

The platform according to claim 1, wherein the lift beam has a double-C-shaped cross-section profile.

### Claim 10 (depends on 5)

The platform according to claim 5, wherein:
the attachment means includes a bracket having a top-hat cross-section profile;
the lift beam has a gap between two back-to-back arranged C-shaped profiles of a double-C-shaped cross-section profile of the lift beam, the gap being configured for passage of the one or more cables of the tower lift;
the attachment means is connected to the lift beam such that flanges of the top-hat profile are connected with upper flanges of the double-C-shaped profile; and/or
the attachment means includes one or more pins supported by the bracket, each pin of the one or more pins being configured for connection with one of the one or more cables of the tower lift when passed through the gap of the lift beam.

### Claim 11

A wind turbine, comprising:
a tower;
a lower platform and an upper platform inside the tower;
a tower lift comprising a transport cabin for travelling from the lower platform to the upper platform or vice versa; and
a platform, wherein the platform is arranged inside the tower of the wind turbine above the upper platform, wherein a lift beam of the platform carries a load of the transport cabin of the tower lift.

### Claim 12 (depends on 11)

The wind turbine according to claim 11, wherein the tower lift comprises one or more cables attached to the lift beam of the platform.

### Claim 13 (depends on 12)

The wind turbine according to claim 12, wherein the one or more cables of the tower lift include a drive cable, a safety cable and/or one or more guide cables, the drive cable and the safety cable being attached to the transport cabin of the tower lift for carrying the transport cabin, and the one or more guide cables being attached to a lower portion of the tower below the lower platform.

### Claim 14

A method for assembling a wind turbine, the method comprising:
a) manufacturing a platform, the platform comprising a lift beam for bearing a load of a transport cabin of a tower lift; and
b) installing the platform in a tower.

### Claim 15 (depends on 14)

The method according to claim 14, comprising, after step b), installing the tower lift in the wind turbine tower, wherein one or more cables of the tower lift are attached to the lift beam, and the one or more cables are configured for carrying and/or guiding the transport cabin of the tower lift.
