Hi Jack, the GMC went like a train never got stuck at all, we were infront of the Scammell and the Kraz in the gully when the Scammell got stuck, but then my truck doesnt weigh 10 tons..... Good day out for one and all, now have to wash out the sand from all the brake drums :shake: :shake:

Yes quite right, and they are BIG tyres :shake:

Yes and a Tank :schocked:

Scammell up to the axles, going nowhere :shake: :shake: :shake: :shake:

Some more

Here are some of the vehicles on the Heavy Trial

Update just spoken to Clerk of the Course, he confirms it is on and there could be a Kraz, matador and possibly a Centurion Tank he has had lots of interest and it could be a bussy day :schocked: Got a friend to try and get up there and do some video work to hopefully put up on the HMVF TV.

Great news, thanks for finding out about the kids, would they be able to bowl / throw from a nearer point, we might need all the help we can get........................ :-D

Well I am sorry if those who are interested are not going to be able to get down there, it was first posted about a month ago, but the MOD are inclined to be a bit slow ! and also it's on the 11th Nov which is not very good for remembrance Sunday, I will be stopping for the silence to remember those who paid the ultimate price..... Hoping to do some video and take some pics of the days events. All the best to all for Sunday.

So if you cant get 5 in a team does that mean they get more turns, how does the turn taking work :? !!!!!!!!!!!!!!!!! With 2 littles can they play or as its a pub do they have to stay at home !!! R3 Islanders Watch out Mrs R3 is well bad after some Brandy, balls could go anywhere. See you there, training in progress....

:goodidea: :goodidea: :goodidea: :goodidea: Nice one I will wire up the electrical bits and bobs now they are disconnected and in the garage and I never thought of taking the strap off....... Typical me always goes for the most complicated first... We will see what the weekend brings. Thanks for the help R3

<qoute> Haven't you got a nice simple problem we can help you with? :whistle: Yea can I have a new spool block :-D This weekend I am going to strip down the spool block and remove all the hoses and test through the valve block, dont rearly want to remove the spools yet..... Dont seem to have problems with the actual rams as I can bodge them and they work ok. The block on top of the centre spool is for the 2 telescopic extensions !!! so dont know why this would be on that, hoses connected wrong maybe, the slewing is achieved by a motor and worm gear to rotate a larger gear on the main upright, this is the far right spool, Far left spool is for the main arm ram and the middle spool is for the 2 extensions as in the pic.

No mechanical lock all rams are free to move, there is one spool valve for each ram so it should be one for one but then it does not seem to do what it should :angry: :angry: Time will tell once I get it a bit more appart.....

Yes I have tried that and it seems to make a bit of difference but not much only a slight note change in the pump but still not enough pressure to do anything with the rams, I will have to have a better look at the spools at the weekend .............

Not sure if relief valve on spool block is any good looks like it was ok when I took it out, all O rings etc ok and was seated on its base and valve part shut !! flow and return hoses are correct as there are "IN" and "OUT" words cast in to the block one at each end and also an arrow pointing from in to out, which is how I am running it ! About taking a ram pipe off the spool block you are right when leaver is moved there is oil flow from that connection on the block but not at any great pressure also there is still flow back from the return hose on the out point of the block, AGHHHHH there is only 1 "IN" connection ( top left ) but there are 2 "OUTLETS" ( bottom right ), one in use, the other is capped off, I assume these are just linked internally ?? The spools themselves will hold the rams under weight so they seem to work ok but can not work out why when a leaver is opperated there is still flow to the tank !!!!!!!!!!!!!! The red eyeball valve with small steel tube round the back of the ram hoses, I think is an emergency bypass valve to allow flow from inlet to outlet.. See attached pic please.

HEAVY VEHICLE TRIAL IT'S ON See link to AWDC Web site...... http://awdc.co.uk/data/awdc.nsf/94ade8bdc4ff098b80256c6700678a0f/fcb88918c74b660dc125737200150cda!OpenDocument

Ok, bought a small truck crane 6 foot tall with hydraulic slewing and one main arm which stows straight down and raises on a ram to a horizontal position or where ever you want it, then 2 hydraulic extensions which push out from the main arm. Problem none of the hydraulics seem to work when the leavers are moved, have a combined resevoir/12volt motor/pump unit and a 3 leaver spool block, have fluid in tank and getting flow back to tank, pump will generate 150 bar in to a dead end before its relief valve opperates, when flow and return hoses connected to spool block get flow back to tank when pump runs but also when any one of the levers are moved I still get flow back to the tank, shouldn't the return flow stop as it is directed to the appropriate ram by the said leaver :dunno: AggHHHHHHH

Hi all, need some technical help regarding spool valves and relief valves etc on a hiab type crane........... Eagerly awaiting

Well the truck is and will be outside, but do have a large gas space heater good enough to heat the local area, ahhh yes not global warming just me and local warming..... :-D

Great news, we will be there with our GMC 352 and kit........

GMC 352, had for 10 years or so, 5 speed crash box double declutching up and down dont need first to pull away, 5th is overdrive. No power steering but once you get it rolling there is no need for it. Good on the flat 40-45 all the time but any hill and well slow, must be the slowest up hill even been over taken by a 353 air portable up hill :dunno: suspect timing ( blue exhaust manifold nearly ) :schocked: Very good brakes if the servo works. Can get the back 8 wheels to step out on rainy wet road if you make heavy braking LOL, when you stop at the lights sideways !!!!!!!!!!!!!!!!!!

Only him, one man band, Malcom he has been doing this sort of thing for years and years.

:schocked: :schocked: :schocked: Try this link me and Jack used him with 2 GMC's and was very reasonable and nice chap. http://www.hmvf.co.uk/index.php?option=com_smf&Itemid=38&topic=4934.0 Might be cheaper worth a try. Mention about the guys with the GMC which the wheel fell off, he voiced his concerns to Roadsure... R Cubed

Just been reading the rest of this thread and it seems some want to bring tracks, has the powers that be been made aware of this, as I know they can be very fussy about tracked vehicles on their turff ..... Only posted this as I would hate for people to be stoped after bringing them all that way. R Cubed
