  1. My apologies I meant insure on chassis no . No plates are for identification purposes so that customs and excise can collect taxes. Police have no interest in collecting taxes and as such have no interest In theory you cannot be taxed until you have MOT hence exempt going to and from test
  2. pretty sure you will find some idiot who will do it for less then £ 1.00 a mile on back load. But is it a runner if so tax it on chassis number book it in for MOT and drive it back
  3. When I first started in recovery 95% of tows on heavies were done with Poles Straight or Swan neck. I hated them then and still do 45 years later. The thing with poles is you have two people each with there own minds thinking they know best working against each other. Plus both have a smugness that tells them can stop safely despite the effects of gradients and corners. Ages ago I did write a couple of things about towing on poles on this thread showing how they can confuse people into feeling safe on this Thread.
  4. Robin we had a three similar cranes all direct from MOD all where crap at lifting. All three we adjusted main relief valve so it blew of at 2750psi and all were good to go. The only one I checked the pressure on was wire locked and valve blew of at 1200 psi that was on a foden F70. I have found a lot of MOD hydraulic equipment has relief valves set about half way to designed working loads both EKA wreckers I have had used to cut out at 12 ton on main winch until altered
  5. To datadawg see height limit in Pennsilvania is 13' 6" drops with a fox or the one with turret on would be touch and go You would have to check but I believe weight limit on rear tandams with single rear wheels would be down around 24,000 lbs.
  6. Centrifugal Force - The False Force An evil word has worked its way into our daily vocabulary, and with it, an incorrect understanding of the way physics works. "Centrifugal Force" ( Latin for "center fleeing") is often used to describe why mud gets spun off a spinning tire, or water gets pushed out of the clothes during the spin dry cycle of your washer. It is also used to describe why we tend to slide to the outer side of a car going around a curve. It is a common explanation...the only problem is all of it is absolutely wrong!!! Centrifugal force does not exist...there is no such thing...it is a ghost we tend to blame odd behavior on.Take for example this common situation. You are riding in a car going around a curve. Sitting on your dashboard is a cassette tape. As you go around the curve, the tape moves to outside edge of the car. Because you don't want to blame it on ghosts, you say "centrifugal force pushed the tape across the dashboard."--wwrroonngg!! When we view this situation from above the car, we get a better view of what is really happening. The animation below shows both views at the same time. The top window shows you the bird's eye view of the car and the tape, while the bottom window shows you the familiar view from the passenger. The car tires on the road have a enough static friction to act as centripetal force which forces the car to go around the curve. The tape on the slippery dashboard does not have enough friction to act as a centripetal force, so in the absence of a centripetal force the tape follows straight line motion. The car literally turns out from underneath the tape, but from the passenger's point of view it looks as though something (a ghost force?) pushed the tape across the dashboard. If the car you are riding in has the windows rolled down, then the tape will leave the car (or does the car leave the tape?) as it follows its straight line path. If the windows are rolled up, then the window will deliver a centripetal force to the tape and keep it in a circular path. Any time the word Centrifugal Force is used, what is really being described is a Lack-of-Centripetal Force.
  7. I should add that there is no such thing as centrifugal force, first true word you have said its centripetal al
  8. Not getting into safe or not debate. But a few things to bear in mind for use in the States. As far as I know the bulk of the states have a lot less weight limit per axle than UK. Also bear in mind your height limits the drops with rack on is very high. By the way I am not anti drops I think the truck is very well designed engineered truck it just has very specific uses in its drops roll but can have lots of other uses
  9. I have at times given advice /views and been castigated for it in deed banned for it. I have given this advice/ views when things are not as they seem and really think I am right. But I have learnt when people don't hear what they want to hear you are wrong. So my only and last comment on this subject
  10. As far as I am aware no problem tow your caravan but don't try filling it with goods you are selling but why would you if you have a matador.
  11. every truck I have ever seen has sliding part nearest to gear box/transfer box
  12. Hows about the one troops who entered a battle field signed off in the great war
  13. Spent a couple of nights looking on net re 750s. In the states scotches where an optional extra as was the tow hitch rear pintal hoolk and various light package. by the way the first 750 was built in 1964, Most where fitted at the chattanoga factory along with what be came the holmes style body and a trawl through pictures on the net show a lot of the earlier ones didn't have the keyhole slots for scotches of rear pintal hook. All holmes 750s supplied to UK came to dial Holmes to start with the early ones having ash frame bodies clad with aluminium some kits were sold on and bodied by bus companies who did there own thing with bodies I have seen these without the tow hitch but just a pintle hook/ tow jaw. then about 1969 dial holmes adopted the Holmes style body and these where built with key hole slots for scotches. But the actual scotches where still optional and I believe added £18 to the £2,200 crane
  14. Thanks for the pictures Tony the scotches on the trailer I believe are standard trailer scotches admittedly more heavy duty than normal used for parking not chaining back to body. the tool kit looks identical to that in CES with omission of scotches hence my thinking the scotches were an after thought by UK mod. To explain above picture first pic shows a good substitute for scotches and works with single or twin rear wheel just let vehicle roll back until axles try climbing over one another before applying handbrake. pic 2 is something I came up with about 30 years ago after I bent rear body work on a daf 3300 double drive wrecker I built it works brilliant but needs 4 scotches but you can use on any twin rear axle even modern ones with modern mudguards. pic 3 was something else I tried a lot of years ago when I was sharing a heavy pull of to an eight wheel on a mucky sloppy site again worked brilliant but took a little initial setting up when it worked took 8 wheeler loaded down in to ground past centre line of axles
  15. Just found these pictures thought i would put them on to show how effective scotch blocks are if you are on good ground or tarmac I tried to find these pics many posts ago when i was trying to explain how to max out on holding power try it out on a pioneer it will make a big differance if you put scotch blocks on rear axle as i described Attachment 38523 Attachment 38524 Attachment 38525 Last edited by cosrec ; 08-12-2010 at 23:59. a post I made a long time ago
  16. Have been off line fora while but it has given me time to think about scotches. Firstly you learnsomething every day I have never seen the picture of the C.E.S before I suspectthis was equipment cobbled together here in the UK the Ts where never shippedfrom the states with them as no provision for anchoring them was fitted. Yesthey have a hard ground soft ground way up but from experience forget usingthem flat side down it creates less resistance then a locked rubber tyre ontarmac/ concrete. The Uk scotches also can do a lot of damage on twin wheel setups if use between the wheels as they have insufficient width and even whenwinching straight out the back they can flip and wedge between the tyres. Ihave had it happen to me on a civilian scammell crusader on the A1 one nightcost me a new tyre as well.
  17. Yes the scotch is of a design made by Holmes wrecker and is much wider and stronger than the british army one. These were only supplied post war and the bodies in this case UK built had a key hole slots in the back valance. they where a very good rig but as I said they came with a disclaimer about damaging pavement and rear body. that truck will have been built as a wrecker around 1973 at a guess
  18. my apologies I have just read original post again I had it in mind you where talking 969 t eg wrecker. No the 981 never was supplied with scotches
  19. the picture radio mike is talking about shows a diamond t a mastiff and a mobile crane recovering a artic. the two wreckers had bodies built at Caxton Hill by dial Holmes they had key hole slots to hang the scotches in. The scotch blocks where much heavier construction than the british army design I may be wrong but I don't believe the 969 t ever came with scotches
  20. A good stop gap is a couple of sleepers arranged each side so that one end is is under the middle axle tyres the other end is on top of the rear axle tyres let handbrake off let truck roll back until axles try to climb over each over. Apply handbrake and foot brake then go for it. You can make anchor points for scotches if you get correct length of chain with a shortening claw on each end. wrap around base of mast brace so claws hang lower than rear of body Maybe put a lump of timber to space them so they at wheel width. Let truck winch back until it is virtually at top of scotch before applying brakes Also there was a disclaimer that came with Caxton Hill built wreckers use of Scotches can damage Pavement and rear body assembly. One other thing if you do happen to come across a tree in the right place either pay load of to it via snatch block or split booms and use as designed. DO not try tethering front end I know there is a winch on there but the W45 is more than capable of folding the chassis
  21. looks like a lot of truck. never seen one in UK but have seen plenty in south of Germany always loaded with dozers
  22. Certainly made that look easy I am fascinated by the whole process hope you have as much success. Brilliant the whole subject
  23. The mere fact you posted it seemed tight hinted all was not good so why go further sort it which way you want
