If you look at this site:
http://www.gova4u.co.il/אודות/
They talk about "גולש מעטפת מבנה" within a more generic "work-at-height" context.

And then if you look at something like this:
http://www.allcleanservices.co.uk/news/2011/10/abseiling-win...
They talk about the use of abseiling for (in this instance) window cleaning and they say:
"it is advisable that the window cleaning technician has had some IRATA (Industrial Rope Access Trade Association) training. IRATA has member companies on every continent and their successful training is based on in depth training and extremely strict guidelines. These guidelines are the structure of unmatched safe working record."

...which brings us to:
http://www.irata.org/index.php
"IRATA is the sole global trade association in the work-at-height sector; it has member companies in every continent."
and if you look at their training courses they are mostly [industrial] "rope access" courses.

Or, alternatively you just could say "abseiling/rappelling" (since that's essentially what it is).
