Winches are for pulling, not dead lifting. Using one as a hoist is a sure fire way to get dead in a hurry. -- Regards, Noddy.

Not like its 1500Kg dead lift >40feet over ya head now is it. It was a toyota 4 pot Corolla donk. A roof isn't generally designed to support a crane. Nor a point-load such as a chain attached to a point on a truss. The truss may buckle or fall down under the load or under "rebound" when the load on the improvised hoist, or the hoist itself breaks free. And when the truss buckles or falls off its support, it can take not only the roof but also the walls with it. The roof truss is designed to support the roof, in the ways that a ROOF is loaded. You can assume no more than that. There are very good reasons why there's a "Crane Code" in the Australian Standards. USE THE RIGHT TOOL! Engine hoists (suitable for occasional use) cost less than $200 in discount stores. 2-tonne capacity ones about $400. The durable ones can be hired for less than $100/day. Building damage tends to be rather more expensive to fix. -- /"\ Bernd Felsche - Innovative Reckoning, Perth, Western Australia \ / ASCII ribbon campaign | For every complex problem there is an X against HTML mail | answer that is clear, simple, and wrong. / \ and postings | --HL Mencken

Winches aren't designed for dead lifting period. -- Regards, Noddy. |
