A plate 600mm squ should allow enough to lift what a 35kg winch
take off the weight of the SWR So you only need support what 28kg tops
So this winch has to come out from underneath,
then frabricate a frame to fit onto the bullbar
easy enough to do, just saying lol
is the winch lifting up or down to remove.
with the plasma on it it would be lucky to be 28kg
My sheds a Stratco and Ive no doubt the c section span
would hold a winch ,
I used it to lift a 285 mud and steel rim when testing that
wheel lifter I designed did it easy thats closer to 50kg
LAST EDIT ::I used 6mm plasma to lift it
