Pulley blocks

wrote: I'm looking for a small sheaved pulley system with maybe two or three pulleys per sheave (if those are the right terms), capable of lifting a max of say 250 kg. I guess the sort of thing used for lifting engine blocks out of cars would be OK. Anyone point me to a supplier? This is towards the upper end of what small yachts would probably require (would you fancy manually hauling up 250kg of sails?), but is well within the safe load rating of mountaineering equipment (strength of human pelvis ~1800kg ; weight of human and gear ~100kg ; one set of equipment needed to work between these limits). You can get the same sort of equipment designed for more industrial uses from "Roped Access" suppliers, e.g. Lyon http://www.lyon.co.uk/workandrescue/ have a relevant catalogue. Other people have asked about alternative ways of doing it - lever and block ; trolly jack ; what beams do you have above the work site to pull on? There's a lot more than just getting the right tackle. I know what I'd look at to assess the job, but I don't think one could assess the job safely from written descriptions. -- Aidan Aberdeen, Scotland Written at Tue, 24 Oct 2006 10:50 +0100, but posted later. |
