Take a look at www.skylaunchuk.com They re-engineer old winches, and may be able to offer advice or even supply the necessary parts, even though they are in the UK. We visited their factory recently, and saw their winches in action at a number of sites. The retrieve winch system is super efficient, and you really only need a single drum winch. They supply their Skylaunch winches with LPG engines, and get a smoother operation than with diesel.
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Colin Campbell Sent: Wednesday, 22 October 2008 7:07 PM To: [email protected] Subject: [Aus-soaring] Winch Design Would anyone out there like to make informed comment upon winch design. We are in the early stages of upgrading our 25 year old winch, This winch has performend well and will be our base line for any new design. It suffers from having 40 and 50 year old components which makes it difficult to source spares. We average about 1100 launches per year. I have suggested a number of topics for consideration. Rope or wire Single or double drum Diesel or petrol Trailer or truck mounted Wide or narrow drum Use of independant motor or prime mover with PTO Source of PTO Retreive winch or self laying or tow out vehicles? Braking of drum(s) during tow out. Guillotine Use of commercial components for cable guide system. Budget Regards Colin C
