Lifting devicesTravers
We design and manufacture lifting devices for all main components of a wind turbine:
- nacelle
- rotor hub
- rotor blade
- rotor star
- gearbox
- rotor shaft
- tower

Load tests offshore lifting devices
The set of regulations requires load testing for seagoing lifting devices as a part of the certification process. We already plan the load test with computer aid during the design process, prove the technical viability and choose the necessary slings.
Means of transport
We design and manufacture means of transport for all main components of a wind turbine:
- nacelle
- rotor hub
- rotor blade
- gearbox
- rotor shaft
- tower
- nacelle cover

Spare part production according to drawings or modelsTrave
We manufacture spare parts and equipment according to your drawings or models. Repairs such as finish-boring of bearing seats, turning of brake discs, etc. are part of our daily work.
- pitch cones
- rotor locking mechanism
- mounting bell
- shims
- adjustment tools
- retaining plate
- spacer sleeve

Production examples:
Special repairs: thread and welding repairs at site
Thread repairs and tower flange boring
azimuth
rotor blade
rotor shaft-hub
tower flange boring
- azimuth
- rotor blade
- rotor shaft-hub
- tower flange boring
Demolished bolts in the main screw connection of a wind turbine such as azimuth, rotor shaft-hub or rotor blade are a commun and unpleasant reality in the years of its use.
The necessary thread repairs require high craftsmenship as well as special equipment.
We have years of experience in the performance of such repairs – nationally and internationally. Furthermore, we are well equipped with special tools: Magnetic drills in different sizes, mounting plates, boring bushes, extra long drills or triple cutters.
The placing of helicoli thread inserts as the last step of the repair is natural for us. With a CAD simulation, we are able to examine the technical viability of each solution.
If necessary, we also develop and manufacture the necessary tools or aids.
Welding work
weld seams of tower and flanges
pitch cylinders
nacelle covers
vibration dampers
- weld seams of tower and flanges
- pitch cylinders
- nacelle covers
- vibration dampers
Demolished weld seams can occur on different components in the ongoing use of a wind turbine. Weald seams of:
– tower or flanges
– machine frame
– nacelle covers or Halterungen
– hydraulical cylinders or brackets
– vibration dampers
We are able to repair weald seams in a high-quality, flexible, and fast manner. The basis for this is our own personnel for the non-destructive testing for the processes PT, MT and UT for detection of ruptures, certified wealding specialists for the repair of the weald seams and a special wealding engineer as supervisor.
