No, Nasher I wasn't back when you posted......But I am now!!
Got back, had a cupper, some cakes my Son made and dished out the gifts from my trip and one and a half hours after arriving home logged on. How sad is that?
This is a last resort method of lifting a trailer which we used to use on the farm before H&S was a fashionable thing it works but has obvious drawbacks.
Find a length of 4''x2'' or similar about 8'' to 10'' long wedge one end at an angle under the axle crossbeam and the other jam into mud or against kerb stone or crack in surface . Very slowly inch forward with tow vehicle if both ends are biting on ground and trailer the trailer will rise !
Have done this on side of M5 years ago , finding a suitable piece of wood is suprisingly easy on Mways due to all the junk that has fallen off trucks lying around and in extremis there is always a nice fence running alongside !
Loosen wheels nuts b4 lifting get the wheel off and lower gain as it is very unstable.
Use your wife or small child as a cushion under the trailer in case it falls off during the lift !
What kept you?
