Which winch wins?

    I fairly regularly get "tonne" bags of woodchip mulch delivered, and I have to get these into my 250L tipper wheelbarrow, which takes about 1/4 - 1/5 of a bag.

    Last time I used a shovel. This takes ages (I had 8 bags to empty).

    So my plan is to build a lightweight frame out of 66/45/2.5 steel angle which I can drop over a bag, hoist it up, make a slit and unload directly into the wheelbarrow.

    I think there are winches that will take a drill attachment (yes, I am that lazy).

    Any suggestions? I guess it needs to able for at least 500kg (dry woodchips are apparently about 350kg/m3 but they often arrive wet).

    Whether or not I can competently build a frame that supports 500kg is another matter. :D

    Chain hoist is your answer here. You can pull a chain can't you, because I'm not pulling it for you :D

    There are however plenty of 12V electric hoists out there none of the cheaper ones will outlast a chain hoist.

    I use an old kids swing frame to lift heavy rocks (approx 250kg) into a trailer. The trick with the frame was to reduce the length of the top bar really short so all the weigth goes straight down the legs. If I want to lift heavier I'd go with 100mm round logs used for kids climbing frames and swings and then get some to weld me up a cross bar with 4 corner sockets for the 100mm legs.

    Would a car engine hoist work?

    Aha, so this sort of thing.

    Interesting. I had intended to make a tall cuboid (1mx1mx3m) with diagonal bracing on all corners, so that I could lower the structure over a single bag, but I guess there might be stability issues.

    The Dexion slotted angle is expensive (€200+VAT for 15 linear metres) but means I can fully disassemble in between hoist jobs (mulching is semi-annual at the moment).

    I really need to learn to weld.

    I'd personally go for a slightly higher capacity chain hoist taking into account that you might need to heave the thing up above head height when setting up. In the range you linked to 1tonne lift is 8kg and 2tonne is 13kg.

    Would some sections of an old galvanised scaffolding tower be what you need as a base? On their own the main sections would not be much use as it has no strength made up open fronted so you could get a barrow in, but 6- 8 sections would give you a good start. Take a look at this to see if you get any inspiration https://www.ladders-999.co.uk/downloads/SaturnTower2014.pdf .
