Ever dream of scaling a wall like Spiderman? Cling Climbing is working on a device that’ll let you: The only caveat is that the walls need to be made of a magnetic material like steel. So what’s the practical purpose of this device? They list such uses as climbing power pylons, ships, silos, or steel bridges to do maintenance or inspections.
Cling Climbing’s climbing method uses “Electro Permanent” magnets for all four limbs. The operator turns off one of the magnets, moves it to the next position, and turns it back on again, allowing him to move both up and down and side to side, albeit somewhat slowly. The “climber” can also tie himself to the handholds so both hands are free to work.
Run by a 24V power supply that they claim can power up to 5,000 movements, the system works on all magnetizable materials with a maximum of 8mm thickness. Even though each limb’s magnet has a 300 kg minimum shearing force, you’d never want to scale any structure without a safety line. (Cling Climbing also recommends thorough training and periodic inspection of their device.)
It doesn’t appear that Cling Climbing’s magnetic climbing system is ready for production yet, but even if it was available you probably couldn’t buy it off the shelf. For further information, you’ll need to contact the company.
