Climbing Crane – LCC140
The Lagerwey Climbing Crane is the world’s first self-climbing crane for the construction of wind turbines.
The crane was invented and developed by Lagerwey to be able to build ever higher wind turbines in usual but also in somewhat more challenging locations. The crane’s limited size, easy transport and quick set-up time provide many advantages for the construction of wind turbines.
In addition, the use of the LCC140 requires a considerably smaller permanent crane installation site compared to the use of conventional crane types.

One working day
|Boom range||32 metres|
|Max. hoisting weight||140 tons (nett weight)|
|Crane construction area||approx. 500m2 (location dependent)|
|Design & Certification||CE (EN13001) & TUV Type Examination|
A multitude of Safety, Electrical, Hydraulic and various other EN norms are applied
|Operation||Radiographic and/or from computer|
|Auxiliary crane||400 ton, depending on situation at site|
Due to the limited size and relatively low weight of the Climbing Crane delivery to site will happen with 11 trailers. In most cases, roads do not need to be adapted at the construction site for transporting the Climbing Crane. The regular requirements for the transport of wind turbine components will suffice.
Small permanent crane stand
Another advantage is that the Climbing Crane requires a relatively limited permanent crane installation site. Depending on the local situation, a permanent crane installation site of approximately 500m2 may suffice.
This saves many precious square meters on the construction site. In addition, the permanent crane stand does not need to be serviced. The Climbing Crane therefore makes locations accessible where large regular cranes cannot operate or where the costs of using regular cranes are high.
Fast build-up time
The construction and dismantling of the Climbing Crane is simple and takes relatively little time. The crane is operational within a day and the hoisting activities can start. Due to the short construction and dismantling time and because of the transport on ordinary trucks, the crane can be transported quickly and easily on the construction site.
The connection of the Climbing Crane with the tower reduces the risk of crane instability during lifting operations. This makes working with the Climbing Crane safer.
The “Blade-beam” specially developed for the LCC140 makes it possible to lift blades without having to use steering lines. This makes lifting the blades much more manageable and also possible in small locations where the use of steering lines is not possible.
Modular steel tower
The Climbing Crane climbs via the skids attached to the crane. The structure of the tower is used as follows:
Furthermore, the “arms” are required to distribute the weight of the crane and the lifting loads over the tower in the desired manner.
Of course we can also build our wind turbines with regular cranes. Every wind project and each wind location is unique and has its own challenges. However, the rule of thumb is; the higher the turbine, the more advantage the Climbing Crane will give you on both crane costs and the costs for the permanent crane installation site.
