Yes if you look close you will see the bottom few inches are round hollow section welded to the square.
It needs to be a slightly loose fit over the ball to get the "lean". Two lengths of thine rope would do to keep it stable. The pulley on the top came from an old multi gym.
I use it on two different vehicles as well, all you need is a tow hitch.
If you’re not up for making something, the david Stretton hoist is brilliant, although in its collapsed state you may struggle for space in a dihatsu, depends how you have the vehicle set up with rear seats etc.... but they’re more than capable of hanging the biggest red stags the U.K. has to offer so fallow are no bother at all.
Sorry i do not have any pictures but i used rr to use a piece of steel tube attached to the roof using a pipe clip and a twin vacum head grip like that what is used to lift glass or panels this then hung over the back and was attached to thinner poles to make an a frame then hang a lift to this
Having wanted something for a while for the back of the Hilux this is what I came up with - modifying an American design. Now I've done one I think I could probably turn out a couple if anyone would be interested.
Here's my even more agricultural version! I thought id knock something up that I can load gen sets or anything else too heavy to lift in by myself, also can draw and load the larger species of deer with as well. The stabilizer legs come off for transport.
It’s a 600lb winch. Haven’t tried that yet! Interestingly the tow bar section had to come out a fair bit not because of the drop down tail gate but the glass section doesn’t go up that far. Therefore the bottom section is longer than the one I did for my Hilux.
