do you work for cross or grap? i am just noticing 2 different names on pumps in your pics and was curious

white booms the worst color if you want to keep it clean

What's in the large tube/line/pipe running down the tip inbetween the boom pipe and boom?

Probably an airhose for an aircuff....

My guess , I have one on My boom .

Or some kind of electric cable , maybee to the horn .

Hey ice, Don't you love it when a customer orders a long boom that is obviously a complete over-kill for getting the job done. Seems to be the case in these picks. It almost makes it harder on the operator when they order a 52meter, and only really needed a 32meter. Looks like a 32 meter Z boom would have been perfect for this job. Sometimes they think bigger is better, when in reality you have so much boom that the majority is wasted because you can't cram that think in there but just so far. A 32Z could have got 3 sections in there and reduced the amount of system needed. Gotta love it.

Probably not an air line. Not enough

pumpers use an air cuff here in the US

I WOULD LIKE TO BE WRONG ;~)

electric for boom  lights on tip section
