Last pic: that’s flash, clearly a powered sheeting system, we only had the manual ones, and we’d usually have to climb on the load to get it to fit (very naughty working at height, but such is the waste & recycling industry)
Sorry i should have said ours are manual like the ones you refer to but our lads don’t climb on the trailer they throw straps over the top and pull the sheet over, i don’t do this but i have watched them.
