RUD's lashing solutions are used to secure wind turbine components during transport. For example, the L-VLBG M36 lashing point is ideal for securing a nacelle.
Jens adds, "When it comes to reliable solutions for safe transport, you can depend on RUD technology. Poor quality load-securing products are the major contributors to accidents in the wind power industry. The cost of a new nacelle or postponing the commissioning of a turbine is costlier than investing in the right load-securing product”. ICE Grade 120 lashings reduce weight while keeping safety paramount. Products such as the ICE-CURT-GAKO ratchet tensioner prevent accidental release, which can happen from vibrations while driving.
RUD offers custom lifting and handling solutions when installing heavy tower segments and rotor blades. Jens explains, “For lifting and erecting large and heavy tower segments, special attachment points are attached to the flanges of the segment. The RUD T-FRB (FLARIBO) flanged load ring was specially developed for such an application and features a patented thrust bearing washer incorporated into the lateral bearing for 90° loading."
Four FLARIBOs are mounted to the top of the segment and two FLARIBOs to the bottom to erect a tower segment. The segment is then lifted using two cranes and erected in the air. The sling chains move over the deflection rollers of the RUD VIP Chain Block (VCB). The VCB allows load balancing for the segment to be positioned vertically. The flange to flange can then be bolted together. When the four FLARIBOs are removed from the top of the tower segment, the deflection rollers of the VCB prevent the unloaded side of the chain from slipping through and falling.
After the tower is assembled from its individual segments, the next step is to mount the nacelle and hub assembly. "A lifting beam is used to lift the pre-assembled rotor blades for the hub assembly. The lifting beam has two generators and two hydraulic systems, which ensures safe assembly of the hub in the event of a partial failure of the system”.
Operation and Maintenance Stage
It is crucial to ensure personal safety mechanisms are in place while conducting maintenance operations. At such dizzying heights, there is no compromise on risk. The PSA-VRS STARPOINT has been specially developed to secure people by connection with the safety harness.
A RUD PSA-VRS STARPOINT can carry up to two persons, offering the advantage of safe securing of the victim and the rescuer in the event of an incident. The PSA can be rotated 360° and forms a compact securing unit with its special non-removable screw.
“The stainless-steel variant, PSA INOX-STAR, is designed for permanent outdoor use in challenging weather because of its corrosion resistance," says Christiansen.
Like installation and delivery, the same products can be used during dismantling and removal. For example, the flange load ring T-FRB (FLARIBO) and the VCB can be used to safely lift pipe segments. The L-VLBG M36 lashing load block, ICE-CURT-GAKO ratchet tensioner and ICE 120 lashing chains can be used during loading and transport.
Onshore wind turbines require products that are resistant to corrosion and challenging weather. The RUD ROV-HOOK, designed for subsea applications, is the first of its kind that can be operated with only one robot arm of a robot-operated vehicle, handling loads of up to 25 tonnes. Due to its integrated unique locking mechanism, accidental unhooking is impossible, which is a big plus point for safety.
RUD’s products offer safe and efficient applications in a wind turbine's life cycle from planning, production, transport and installation to maintenance and dismantling.

Wind power is currently the cheapest source of large-scale renewable energy, which involves generating electricity from the naturally occurring power of the wind. Wind turbines capture wind energy within the area swept by their blades. The spinning blades drive an electrical generator that produces electricity for export to the grid.
The Australian renewable energy industry accounted for 35.9% of Australia’s total electricity generation in 2022, up from 32.5% in 2021. This is more than double before the boom started in 2017 (16.9%). While there is still a significant way to go if Australia is to meet its ambitious 82% renewables by 2030, there has nevertheless been encouraging progress.
There are currently over 3,000 wind turbines in operation in Australia, generating enough electricity to power over 2 million homes. Some of the largest wind farms in Australia developed over the last few years include the MacIntyre, Coopers Gap and MacArthur.
While the wind energy industry creates jobs and economic opportunities in Australia, employing over 10,000 people and an additional 10,000 jobs by 2030, it faces a lot of operational challenges, such as:
RUD Solutions for the Wind Energy Industry
RUD is a world leader in lifting and lashing and offers a wide range of solutions for the wind energy industry to increase safety and efficiency in the design - manufacturing - logistics - installation and maintenance processes.
Reliability and Safety are Key in the Supply Chain
According to Jens Christiansen, RUD Slings Division Sales Manager for Germany, Austria, and Switzerland, "Logistics already starts with the design. The designer must plan how the component will be assembled, transported on the road or ship, and installed on-site in the design stage itself. As we know, wind energy includes components that are large and very heavy, which makes the job complex. As the leaders in lifting and lashing technology, we offer versatile solutions for all stages in a wind turbine life cycle”.
Where can RUD help?
RUD’s products and services are used throughout the life cycle of a wind turbine, from the design phase to decommissioning.
Idea and Design Stage
RUD lifting points are reputed for top quality, ergonomics and safety in lifting technology and load securing for more than 35 years. We offer more than 700 tested boltable and weldable lifting points in load ranges up to 250t, which meet maximum safety requirements. Our engineers can work with wind turbine manufacturers to design lifting and lashing solutions that meet the specific requirements of each project.
Whether lifting or moving small components or huge rotors, RUD has a solution for every task in the production process. Lifting, handling, or moving during production can be made more efficient using standard products. For example, the VLBG-PLUS Load Ring is suitable for lifting, rotating, and turning operations due to its large load-bearing capacity, excellent material properties (temperature/corrosion resistance) and ideal design. A VLBG-PLUS can be rotated 360° or swivelled 180° in the direction of the load. This makes it extremely easy to hook the sling into place, saving time and money.
RUD has also developed a Tool Mover with a capacity from 2.5 tons to up to 64 tons. RUD tool movers are widely used and accepted safety devices to guarantee the safe rotating and turning of turbines and critical components.
