Craning a Launching Alternative for Some Clubs….??

Corby craneWe had some chatter on the Blog recently about the attraction that cranes might have over slipways at some Clubs.  Indeed, to my surprise, we did find a few UK Clubs who crane already.

For Dragon craning, we had pretty big bits of crane which cost serious money – and would be too much for many FF Clubs to consider.  And so I was delighted when Richard Blaquiere wrote in from Perth W.A. ….

I’ll try and get a picture of the FF crane at Freshwater Bay. I’ll also get some basic measurements. Height of the boom of the ground, and its length. I did a design of a small ff15 crane for our club, before they built the new facilty.  It was very simple, similar to the small cranes they use to lift dingys off large boats. Remember a heavy 15 is 350 kgs. on weight 15 is about 315 kgs. Have a look on EBay for a small material lift, that has SWL (safe working load) of about 750 – 1000 kgs. The material lifts need 240v single phase power. ie stand power point. They all usually have a hand held pendant that controls the up / down of the hook. They are very cheap in Aust. I would think they also quiete cheap in the UK. The design I had done used one of these material lifts.  The gantry was made from 150 x 50 x 3 RHS, and the base swivelled on a Wheel hub and a stub axel. All hot dip gal after fabrication. 

I’ll see if i can find the sketch that i did.

cheers, Richard Blaquiere

Richard also pointed me at the type of motor that an FF crane would need.  I was amazed to see that we’re only talking a couple of hundred pounds. This is what they look like… not large at all.

  3. Although more expensive and needing three phase power, a two speed (4 to 1 ratio) hoist has great benefits in precision and speed that users greatly appreciate. We have such a hoist at Canberra, with three phase power provided from an available single phase supply via an electronic phase changer, which was much less costly than running a three phase supply.
