Column Climbers are an attachment you strap to your boots to allow you to climb steel I beams. I have never seen them in use in Australia as of yet, but they look pretty neat. Not as useful as a scissor lift but much cheaper and a better option than a ladder in my opinion. They cannot be used on the round hollow section columns or square hollow sections as they need to hook into the flange of the I beam.
Anyone with any experience with the product happy to hear what you think of them.
