Due to the compact transport dimensions and its low weight the RBC lowers the transport effort as well as the costs. With all pads retracted the overall dimensions are just 13 m x 3 m x 2.95 m. This ensures easy shipping with a permanent permit – no special permit necessary. The RBC doesn´t have to be disassembled in order to ship it – and no time-consuming assembly on the next construction site. The RBC is always operational and can start work in just minutes.
Unload – Switch on – get started!
There is no on site assembly required. Between arrival on site and slinging the first blade a maximum of 15 minutes is required. To install or dismount a blade only a single crane is necessary. Thanks to the low construction height the height of the hook can be optimized for large hub heights and therefore time and money can be saved.
The benefits of our Rotor blade clamp construction
- No assembly required
- a single crane is sufficient for installation and dismounting of rotor blades
- The RBC is always ready to be used and can start working in just a few minutes
The RBC is the first ever yoke to nestle its adaptive support pads up against the blades surface to generate a widespread, perfectly fit contact surface. This not only makes the RBC future proof, but also a great investment for maintenance companies since it is backwards compatible with all existing blades. This individually adapted contact interface applies very low pressure onto the blade, which guarantees a damage free operation.
The 14 supporting arms with their elastic and gimbal-mounted pads form the adaptive blade interface. The blade is very gently embedded in these and held securely. When closing the gripper, the individual pads nestle against the blade and create a form fit with very low pressure. They create an ideally adapted load bearing surface, which is large enough to lower the pressure on all contact surfaces to a uncritical minimum. Four additional adaptive safety pads clamp down from above and ensure encompassing the blade and provide a secure hold.
The pads automatically and individually adapt to each and every blade, therefore it is suited for each existing and future blade.
The RBC is an all round talent which makes your company independent from blade types, -sizes or -manufactures. Completely adaptable without changing parts or any kind of re-fitting work. The blade type as well as the blade orientation (root on clamp side A or B) is selected on the remote control and the corresponding parameters are set.
Thanks to the gimbal-mount the pads automatically nestle up against the blade contour. This ensures an optimized contact with the blade surface as well as even distributed reaction forces. Spring loader pre-position adapters with plastic gliders orient the pads relative to the blade before they make first contact to ensure no shifting forces are present. They press perpendicular against the blades surface. The Pads are quickly exchangeable without any tools and can be changed to special ones for areas with vortex generators.

The all-round talent for every blade
Ready for use at every temperature, every weather and around the clock
The pads adjust themselves automatically and individually and therefore the RBC is suited for all existing blades as well as future generation of wind turbines. This makes it the all-round talent for every challenge and frees you and your company from blade type, weight and manufacturer dependencies. Completely adaptable without changing parts or any kind of re-fitting work. The RBC guarantees secure grip at +/- 30° tilt angle without any safety ropes.
In order to compensate the different centers of gravity with and without a blade as well as different types of blades the RBC has a NC controlled COG compensation. This ensures that the gripper stays horizontally no matter what blade is mounted. Uncontrolled swinging and oscillating when releasing the blade and therefore the risk of accidents and damages are eliminated.
When picking up the laid out blades, the RBC can adjust its position relative to the blade thanks to the pitch and tilt functions (the real world angular position of the blades always differ from the theoretical ones). The pitch function can adjust +/- 8° while tilting is possible for +/- 6°. The set angles are monitored and independently shown on the remote controls display. With the tilt and pitch functions it´s possible to grab the blades under real world conditions independently from their angular position and even compensate for positioning inaccuracies while slinging. You want to install and dismount blades at 30°? No problem, since the advanced RBC-D can mount and dismount blades at +/- 30° – without any need for safety ropes!
The construction of the RBC sets a new standard in regard to the headroom. The distance between the center of the RBC and the crane hook is with just 3.5 m incredibly short and offers therefore increased and unrivaled flexibility in regards to planning a construction site and choosing a crane configuration.
