Access Technology for Wind Energy Power Plants


KÄUFER provides certified and type-examination tested mobile platforms and access systems for inspecting, cleaning and repairing wind energy power plants. KÄUFER access systems are simple and easy to transport and install, regardless of the local conditions.

Ascending to and descending from any height is operated by electric cable winches. The reinforcing bar spacer construction can be adjusted electrically or mechanically, thereby enabling an optimum working position to be achieved in relation to the rotor blade. Cable suspension is either fixed to the rotor blades or the machine cabin, depending on access system.

We constructed the first access systems for wind energy plants as early as 1996. A large number of other pitch-controlled or stall-controlled systems have been used to the present day on wind energy power plants at home and abroad.

As a result of continual evolution, we can propose various solutions for repairing, maintaining and cleaning all plant types.
Use our long-standing experience as one of the global leaders in height access technology.

We provide the following benefits:
  • KÄUFER access systems for wind energy power plants are TÜV type-examination tested and certified according to EN 1808
  • Our own construction department including production and assembly enables us to accommodate all customer requests
  • We provide active and professional advice
  • Using KÄUFER access systems enables economic and safety benefits to be obtained
  • Additional components allow us to use just one access system type to access both pitch-controlled and stall-controlled wind energy power plants
  • Optimum adaptation to the rotor blade through adjustable sliding platforms enables a qualified assessment and specialist repair work to be carried out
  • System can be set up in approx. 2 hours by only 2 people
  • The payload is 400 kg, which is equivalent to 3 people
  • Complete transportation of the cable platform on one trailer
  • Useful additional components such as closable assembly cages

Type: K-WKA-C-2W

Cable speed: 9 or 9/18 m/min., payload: 400 kg, dead weight: 1200 kg,

Technical equipment:
2 cable winches TIRAK X 820 P, 2 arrestors, central control with inclination limiting device, overload shutdown, 230 V socket

A perfected concept enables the access system to be erected and ready for operation with just a few steps in a very short space of time. The cable winches, reinforcing bar spacers etc. are completely pre-assembled on the access system. Cable suspension in the case of type K-WKA-C-2 W is fixed to the machine cabin. Advantage: The cables do not need to be reassigned when working on the next rotor blade.


Sale, Hire and Installation

Variable working platforms with just one cable winch can also be used for inspection and repair work at the tower shaft or rotor blade.
Access systems for hire can be delivered with a trailer.
Installation will, of course, also be carried out if requested.
