Its rated at 600Kg full in and I think 400kg out....... but it lifts a tonne bag ok! The crane was electro/ hydraulic 12v, but I drive it from my engine driven hydraulic pump and it has a lot of grunt.... very good on timber with a pair of self gripping tongs, and the retractable arm will pull stuff in to where you want it!
If you look close you can see a jack leg beneath? This is a bit of box with a small ram inside and a car towball on the top, I extend this to take the weight (and break beads on tyres!) The ally body is a tipper so I have an air operated bed lock on the other side to keep things square?
The crane will actually take the spare off the roof too!
As I get older I have adapted stuff to save my back!
