## Abstract

A modular system for transporting wind turbine blades in at least two different spatial arrangements comprising two or more root end transport frames having a height H for supporting the root end, wherein H<D (D=bolt circle diameter), and two or more first tip end transport frames having a height H1 for supporting the blade towards the tip end, each first tip end transport frame has a base frame and a support bracket provided on top of the base frame, wherein each first tip end transport frame is stackable on top of a root end transport frame and vice versa, so the system is operable to stack successive blades in an alternating root end to tip end arrangement. The first tip end transport frame is replaceable with a second end transport frame that increase the inter-blade spacing, or with a tip end or a root end distance piece.

## Claims

### Claim 1

A transport system for transporting wind turbine blades in at least two different spatial arrangements, each blade having a tip end and a root end, each blade further having a bolt circle diameter D at said root end, the system comprising:
two or more root end transport frames each having a height H for supporting a root end of one of said wind turbine blades, wherein H<D;
two or more extendible tip end transport frames for supporting a portion of one of said wind turbine blades towards the tip end of said blade, each extendible tip end transport frame comprising a base frame, at least one vertical extension means for extending the height of the tip end transport frame and a support bracket provided on top of said base frame for receiving a portion of a wind turbine blade;
wherein each extendible tip end transport frame is stackable on top of a root end transport frame and vice versa, such that the transport system is operable to stack successive wind turbine blades in an alternating root end to tip end arrangement with at least two alternative inter-blade spacings created by varying the height of the extendible tip end transport frames via the vertical extension means.

### Claim 2 (depends on 1)

The transport system of claim 1, wherein the vertical extension means are suitable for extending the height of the tip end transport frame stagelessly.

### Claim 3 (depends on 1)

The transport system of claim 1, wherein the vertical extension means consists of one or more threaded legs suitable for continuous height adjustment and at least partially received in the base frame of the extendible tip end transport frame.
