Device for establishing admittance and transport of cargo to and from a wind turbine construction above ground level

摘要

A device for establishing admittance and transport of cargo to and from a wind turbine construction above ground level and having a part which can be raised and/or lowered by wires and winches located at ground level and connected with snatch blocks attached to a part so that it can be raised and/or lowered in relation to the construction. The part has a number of travelling crabs according to the numbers of winches and the travelling crabs are guided of the wires between the winches and the snatch blocks, and that the part with the travelling crabs is displaced upwards or downwards by the wires. Advantageously, the wires are used for both hoisting the part and as guide for the travelling crabs.

1. A device for establishing admittance and transport of cargo to and from a wind turbine construction above ground level, comprising
a part that can be raised and lowered relative to the wind turbine construction, at least two synchronously driven winches located at ground level in a side-by-side relationship, a plurality snatch blocks matched to the numbers of winches, the snatch blocks being attachable to a section of the wind turbine construction above ground level in a side-by-side relationship, cables or wires running between the winches and the snatch blocks, and a number of travelling crabs matched to the number of winches, each of said travelling crabs comprising at least one first upper wheel and at least one second lower wheel, wherein the travelling crabs are guided on the wires running between the winches and the snatch blocks, wherein said part is displaceable with the travelling crabs upwards or downwards by said wires, and wherein the wires run directly from at least an outermost of the snatch blocks to said travelling crabs and then directly from the travelling crabs to the synchronous driven winches, wherein the snatch blocks are multi-cut, and wherein the at least one first upper wheel of the travelling crabs is multi-cut and cooperates with said multi-cut snatch blocks.
