Abstract
When producing large work-pieces, an operator often faces the problem of accessing all areas of an inclined, high surface. The present invention proposes a device and a method for climbing up inclined surface wherein a plurality of steps are attached to a flexible support, which can be provided for example by a mat. The present invention finds a particular convenient application in the field of wind turbine production, for example when layers of glass fibers have to be laid onto the walls of a mould.
Claims23
A method of producing a wind turbine blade, comprising:
- providing a mould of the desired shape, the mould having a longitudinal direction (L);
- laying one or more layers of reinforcement or foam material onto the inner walls of the mould;
- and
- positioning in the desired position the one or more layers of reinforcement or foam material by using one or more devices in order to climb up the inner walls of the mould.

A device for climbing up an inclined surface comprising:
- a flexible support comprising a back face and a front face, said back face of said support being adapted to abut on said surface during operation of said device, said flexible support being adapted to conform to the curvature profile of said surface to be climbed, said flexible support being suitably extended so as to distribute across said surface the weight of an operator climbing up said surface during operation of said device;
- fastener for fastening said device so that the position of said device with respect to said surface is substantially constant during operation of said device, said fastener being connected to said support;
- and
- climbing elements firmly fixed to said front face of said flexible support, said climbing elements being adapted to allow a user to climb up or be supported at a predetermined position on said surface.
