Can you longline with an EC 145?
I have seen short line water buckets hanging underneath and winches being used but have never seen one with a 100 -150' long line.
Can it be done? Is it done? Could they replace the Bell mediums in utility operations? |
We have used long lines on BK117s for buckets for years, and I frequently used 50' and 100' lines when slinging. My BK was the first to be used for bambi buckets in 1997, but it took me a couple of years to work up to 100ft lines after which I vastly preferred them to a direct attachment to the hook.
I wouldn't expect the EC145 to be very different from the 117? Edit: True North have provided their EC-145 to the RFS in NSW for Helitack for some years now, looks like a 50ft line here but I know they use longer. http://www.truenorthhelicopters.com.au/f.ashx?v=986740 http://www.truenorthhelicopters.com.au/f.ashx?v=986743 |
Yes you can, was just up with Pacific Helicopters in Goroka, PNG shooting them long lining with their new H145.

Long lining from a 145
If you mean possibly replacing mediums, I think not. A 205/212 can lift 3000lbs at sea level. The 145 I fly here in Alaska does about half that on a good day. A lot of variables, of course, but the 117/145 is nearly 3,300 lighter...much smaller aircraft.

Hook capacity of a 117 is 1300kg/2865lb.
I think you'll find the 212 cargo hook limit is 5,000lb, not 3,000. |
John, really?
I have flown almost every variant of the 205/212 and NONE will lift 5000 lbs.
A 212S (1x17B) with Fastfin and strake kit at sea level, +15 C and no wind with 200 lbs of fuel will lift about 4500 lbs. (OGE by definition) Yer average VFR (~6400 lb empty weight) 212 with -3 or 3B's will do about 3300-3400 lbs under the same conditions. A straight 205 maybe 300 lbs more. You are, of course, technically correct - the 205/212 hook limit is 5,000 lbs. |

Great information that is very difficult to find on the Airbus website - Thanks everyone.
I am curious as to the precision one can do with the 145 and a longline (construction/powerline work). http://i385.photobucket.com/albums/o...P1170284-1.jpg Is there a preferred line length? Do you always fly with the door off as in the picture (Thanks John)? Is there a bubble window (like in the Bells)? Does the crosstube get in the way as in the 135? Those look like outstanding mirrors - are they used for 100'+ loads? Can the 145 land on towers (ground resonance, control, visibility etc)? http://i385.photobucket.com/albums/o...8/P1170328.jpg |
Again, I can only refer to BK117 experience but these are a few jobs we did:
F1 car, practice before slinging into the Melbourne Tennis Centre http://www.eacott.com.au/gallery/d/5...car+lift+3.jpg Lots and lots of concrete pours for the Mt Hotham Ski Lift company, all about 5,700 ft amsl http://www.eacott.com.au/gallery/d/7...belly+shot.jpg Stainless steel vat lift for Heinz factory http://www.eacott.com.au/gallery/d/7...at+lift+02.JPG http://www.eacott.com.au/gallery/d/7...at+lift+02.JPG 18 metre flagpole on top of No 1 Queens Street: 6 bolts with 2mm clearance on each http://www.eacott.com.au/gallery/d/7448-2/IMG_0226.JPG http://www.eacott.com.au/gallery/d/7451-2/IMG_0231.JPG http://www.eacott.com.au/gallery/d/7454-2/IMG_0232.JPG A backyard poolside bench for a Toorak residence: 1,250kg http://www.eacott.com.au/gallery/d/7...07+view+01.jpg And Mitch made this meccano set: http://www.eacott.com.au/gallery/d/7...May+2003-7.JPG into this, up at Cradle Mountain http://www.eacott.com.au/gallery/d/7...May+2003-9.JPG So yes you can longline with a BK117, and no reason why not in an EC145 :ok: |
