Well, the person's real but it's just a made up name, see?

Second video much better than the first. Super control from the pilot.

Not sure what happened with the first one, it's longer but the link takes it to part way through.

Anyway, snowHeads is much more fun if you do.

Usually more of a crew effort. (Said the ex Puma crewman  )

I remember that area had a row of Pomas and was a great early intermediate ski area circa 1984.
Is it still connected to the skiing at Verbier ?

Wow, I can't believe they don't have any better options than having people positioned directly underneath a suspended load!

@damanpunk, Switzerland, the land the the HSE forgot.
@Peter S,
Still a great beginner/intermediate area, and a couple of long challenging reds. Mont Fort and Verbier is about 90min ski away.
As much as I love the area, the links from Thyon to Siviez and beyond are not the best but I have not queued longer than 5 min for a lift in 15 years of going there.

When we built the Poma at Yad Moss we used a three sixty digger to lift the pylons onto their foundation. We fixed the bolts onto their studs using a giant Stilson wrench. Pylon five was the longest and heaviest. It had originally supported a turn in the Poma line along its original route at Le Collet d'Allevard in the French Alps. As the digger driver was lowering it into place the strop holding it onto the bucket snapped. We just about had time to run clear whilst the driver managed to push the pylon away from his cab. It fell harmlessly onto the boggy hillside. He then expressed his displeasure with us in quite forthright language, for using second hand lifting gear, pointing to his fibreglass roof which clearly would not have saved him had it fallen back onto the digger! Our broken strop was evidently way beyond its safe life. We found some thick chain and used that instead. I don’t recall any more dramas after that.
Poma pylons are essentially just pipes. I think a standard eight metre pylon without any arms or wheels weighs about 600kg.
All our pylons are still standing and the tow is working well.

No need for H&S hysteria.
Drop in the pylon. Bolt it up. Job done.

Often wondered if there's an optimum length of cable for lifting heavy weights by helicopter.
I presume there has to be some clearance to avoid the downdraft effect, but the longer the cable, the more the pendulum effect.
Is there some sort of tables used for calculations, or is it down to the pilot/crew from experience dependent on conditions?

And love to help out and answer questions and of course, read each other's snow reports.

In the mil, there was (is?) an AP- Air Publication dash 1105. It listed all the mil stuff that the Puma in my case might be expected to lift. Guns, recoilless rifles, vehicles etc. The 1105 would specify the rigging; and if appropriate, the strop to use. This was arrived at after specialist test flying. I only ever used 8', 20' and 80' strops. Brianatab is right about downwash and the pendulum effect. Things not in the 1105- the crew, and primarily the crewman, would decide on a strop length.

must be very hard lining the bolts up especially as they must keep their heads fairly low incase they wind catches the pipe and it swings, we put up agricultural buildings when we need a new one and that needs care working 15 ft off the ground in a man cage on a telehandler, working at greater heights up a ladder is very skilled work, perhaps they are related to fred dibnah
