i would guess that in the days before the joining bar which does serve a useful purpose they engaged and disengaged very easily.. its doing two at once that has made them a bit less than ideal..
for what its worth mine slips in the mud.. my wrench is about as long as it can be the end hits the ground while trying to engage the nut.. any longer and it would not go on.. mine is the one you can buy from the garage..
having said that i would still not be without one.. he he..
If you know what side of the caravan has the widest side (female side) of the joining bar, operating it from this side may be a bit easier as that side may flex a little less than the thinner male side of the bar.
all good advice. glad it's not just me!next stop a garage to buy a longer wrench and might try the lubricant although as its new I would have thought it would be well lubricated when fitted.
mine dosnt really slip but i have 1 inch high ridge i sometimes take mine over.. when its wet and muddy the rollers will slip.. its in their nature to hence the super heavy spring....
but when it comes down to it.. fancy radio control unit apart a caravan motor mover is a Heath Robinson kludge contraption bolted on to something not designed for it in the first place.. they work remarkably well for what they are.. :)
they work but i would not expect a 65 year old grandmother to engage or disengage a manual one.. some folks will be better off buying the more expensive motor engage one..
press a button to move it press a button to engage or disengage it.. why not do the job of making life easier properly.. if you can afford it.. :)
currently its a bit like starting a car with an old fashioned starting handle.. perfect once its going.. but
trog
ps.. an option to do both sides separately (half the torque needed to engage) would also be usfull.. that joining bar is another kludge.. it should at least be offered as a choice to have it or not have it..
And whilst we are on the subject, what sort of general maintenance should you do with these?
It's sat on the drive all winter getting the weather. I wondered if a bit of WD40 might be a good idea, or maybe a cover of some sort, just to keep the worst of the winter weather off the workings?
Could it be possible that tyre pressure's are to high? Recommended pressure for my ( C rated) tyres are 65 lbs, but on working to the formular for calculating my pressure's they are 51 lbs. I inflate to 52 and never had any problem engaging my Powrtouch from one side. I'm also getting on in life (71) with some arhritis in hands and wrists.
that 65 psi isnt the recommended pressure its the maximum pressure they can be inflated to..
why so many people get this wrong i cant figure..
my tyres have a maximum pressure of 65 psi.. they also have a maximum load of 730 kg.. at the maximum load they need to be at the maximum pressure..
my van weighs around 1100 kg or 550 kg per tyre.. i blow mine up to around 45 psi..
but i dont think it makes any noticeable difference to the to the effort needed to engage a powrtouch mover..
i am tempted to measure what torque is needed.. it could be done with any torque wrench.. something akin to to removing a wheel nut i would guess.. something easily done by some but not by others..
i dont actually own a torque wrench else i would then we could all argue how hard it is to apply 75 foot pounds.. i recon the mover needs at least a 100 foot pounds.. but i am guessing at that.. the makers would know exactly.. they will have measured it.. he he
Hi Trog, the 65 I'm referring to was on one of the caravan tyre pressure charts available online, I'll do a search to see if I can find it. My van has a max weight of 1100 Kg. The formula is also online, there's no way I would or need to inflate to max pressure.
