As wind turbines becomes higher and higher the technical specification of rescue equipment must also evolve at the same pace. In a branch where most products looks and operates the same way there was a need for new technology of safety equipment.
The challenge of making the device has been thrilling from the start all the way to the end. Revolutionizing a product area is always inspiring, when it concerns human safety and environmental energy in the same project, this has been a golden result.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The unique properties of ResQ DD are that it is specially designed for heavy loads and high heights. The main strength is the patented new technologies along with the technical specifications, the markets first true device developed for operating up to 280kg from up to 600 meter.
With all new and patented features to the market like direct drive configuration, manually engageable hoisting mechanism with self-locking worm gear, the ResQ DD represents innovation with the user in focus.
OPERATION / FLOW / INTERACTION:
You hang the device in an anchor point in the wind turbine, attach the carabiner to your safety harness and let go and let the device work for you.
When hoisting, engage the hoist mechanism by pulling the handle out. The hoist mode is now engaged and you can hoist the load up or down. The mechanism can be engaged and disengaged both with load and without. Fold in the crank and descend to the ground controlled by the device.
PROJECT DURATION AND LOCATION:
The project started during the fall of 2010 and was finished during the summer of 2013. Key places have been Gothenburg and Halmstad in Sweden. Tests have been performed both in Sweden and in Denmark. The test load specification of 280kg and 200m of height has been quite hard to find test areas to perform tests at. We have been developing test equipment, both tests rigs but also portable equipment to mount on large towers to be able to perform the test that has been necessary to perform.
FITS BEST INTO CATEGORY:
Engineering and Technical Design
PRODUCTION / REALIZATION TECHNOLOGY:
Even though the product itself stands out as a great innovation, but it also is a great business opportunity is that the production methods is well thought within each production area.
The main body has several functions built into one molded piece. The tools is divided into six pieces working together making the part cost efficient and also aligning the production method match the needs of the actual part. This way of thinking has been along the project all the way to finished produced parts.
SPECIFICATIONS / TECHNICAL PROPERTIES:
Dimensions: 157x225x283 including hook.
Weight: 3,7 kg
Rescue, evacuation, wind turbines, personal safety, innovation,
Since the wind turbines are getting higher and higher and the need for more and more service engineers doing jobs at the top of wind turbines the need for safety equipment to match the evolution of wind turbines.
The scoop has been to develop a device that manage the technical specification and at the same time be user friendly and safe as it can possible be. The research process has involved mathematically challenges of the designing process but also challenges regarding tests of the equipment.
Actually to find places to test the equipment. 280kg with a safety factor of 25% makes 350kg test mass. The height that this should be dropped from is 200m several times. Even though the product development process has been very hard from time to time we have had the most trouble of testing it.
Also, insights on how these products are being used in real life has been a journey to map and figure out the best design solution to correlate with the preferred way of operating the device, has been hard from time to time.
