A.T.I. Abseiltechnieken specialises in hard-to-reach locations. Where scaffolding, aerial work platforms or cranes cannot be reached, our rope access techniques are often a good alternative for carrying out maintenance work. This was the case with two masts above the WTC building in The Hague. The lights on top of the pylons needed replacing and our expertise came in handy. The work could also be beautifully visualised.
