I have a back problem & have to get the wife or daughter to wind the rollers on, They struggle to wind it on to give enough pressure for the rollers not to slip.
Would it be safe to use a ratchet & socket or long handled torque wrench? I think i read that it uses chains and these can snap. Never heard anyone doing this and i dont want to be the 1st.
I use the one supplied with it. I just changed the van and the steady winder which came with the new van would be lucky to have enough torque to stretch elastic!
I also tried using the 24v battery drill with steady winder socket but it didn't have the ooomph to wind the thing on so there was enough traction to move the van.
If I have given it a good greasing lately, I use my portable drill. Otherwise I use the handle supplied.
I'd be quite comfortable about using a socket and ratchet,this would probably double the force, but I'm not sure why you would ever want to use a torque wrench.
I didn't think they had chains, but I might be wrong.
I use the winder supplied , my battery drill hasn't got enough power . If your struggling i'd use a torque wrench as it has a longer handle than a normal wratchet . Use a 1/2" drive extension to keep the wrench away from the caravan side .
I puchased a Dewalt 18v battery drill when i fitted my enduro mover and it applies the rollers with no probs at all, just make sure the setting is on high torque. To be honest i don't even take the handle supplied with me.
They are chain driven though I can't see how applying the rollers will cause the chains to fail, the way they could snap could be if you tried to move the van with the handbrake on or if you press/release,/press/ release the direction buttons (unless somebody else knows different).
