cosrec Posted May 22, 2011 Share Posted May 22, 2011 in what respect do you mean lock it eg throw it of inadvertently by pressing the wrong button or is there an actual locking mechenism that holds the pallet rack on. Quote Link to comment Share on other sites More sharing options...
xtreme Posted May 22, 2011 Author Share Posted May 22, 2011 Actual locking mechanism . curious to what the switch postions are as I think position 4 looks like a picture of a seat belt and 5 looks like bed with 2 arrows . Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted May 22, 2011 Share Posted May 22, 2011 Actual locking mechanism . curious to what the switch postions are as I think position 4 looks like a picture of a seat belt and 5 looks like bed with 2 arrows . The operations for each switch position are as follows; 1. AUTO - normal selection, when used, controls via proximity switches, the action of the rams in both load and unload operations. 2. MAN HA (Manual Hook Arm) - will operate hook arm only, used when an electrical fault occurs, ie proximity switch fails. 3. MAN MF (Manual Main Frame) - as above but main frame rams. 4. MAN TRANS (Manual Transport) -this is used after a manual operation, to de-pressurise the rams. 5. AUX - used when supplying hydraulic power to another DROPS LHS which has failed.

Bran D Posted May 22, 2011 Share Posted May 22, 2011 Use switch position 1 to load rack. Continue the load operation until the "no trans" light goes out. This signifies its safe to drive off. Dont drive off with switch in any other position than 0. See attached image of lhs control panel. Good luck, let us know how it goes. lhs.pdf Quote Link to comment Share on other sites More sharing options...
mash Posted May 22, 2011 Share Posted May 22, 2011 If you are doing this for a brake test there is a much easier way of doing this. there is a load sensing valve i think between the 3rd and 4th axle, you can simulate weight by using a bungee. If that is what you need i will try and get you some pics of how its done. that is a much easier and less fuel consumption way of doing it. Mash.

Mk3iain Posted May 22, 2011 Share Posted May 22, 2011 The load weight is required for the brake testing equipment, the test station will/should have load simulators! But best to be sure with your own load I recon. Quote Link to comment Share on other sites More sharing options...

robin craig Posted May 22, 2011 Share Posted May 22, 2011 Pardon me for sticking my big nose in, but I can't help but ask you Dan, as a representative of the UK heavy MV contingent, why you guys use web straps instead of chains for securing an object like that? I see one of your straps runs through the drive sprocket, so you have fabric over an edge. I'm very curious as I see loads of UK pictures with vehicles secured with Spanset or other straps. While we do use rated straps but only with the metal terminations onto a "hard point" not through something. R Quote Link to comment Share on other sites More sharing options...
cosrec Posted May 22, 2011 Share Posted May 22, 2011 Yep makes me cringe as well. Ratchet straps are great but they dont like sharp edges still in this case i aint paying for them so it dont bother me to much Quote Link to comment Share on other sites More sharing options...

Grasshopper Posted May 23, 2011 Share Posted May 23, 2011 I believe the rating of the securing method used should be twice the weight of the load in a forward direction and 1.5x the weight in a sideways direction. For the record we use chains on our CVRTs. I did once get a phone call from a REME friend of mine asking how much a Scimitar weighed. When I enquired why (as he should have known), he said he was picking one up with a DROPS and had forgotten to bring securing chains and only had ratchet straps! I think he used about 12 to get within the required ratings. Quote Link to comment Share on other sites More sharing options...
LoggyDriver Posted May 23, 2011 Share Posted May 23, 2011 You need chains on that load, with additional straps. The load will bounce due to the suspension of the CVRT. This will rub on the straps and could cause a failure. There are specific loading plans for various equipment types loaded onto flat racks. I was a DROPS op for 8 years, we were always given loading cards with a diagram of where the straps/chains need to be fitted for different types of load. Straps in the main are only good for pallitised loads. Do yourself a favour and get a couple of chains. They are safer and quicker. Quote Link to comment Share on other sites More sharing options...
sirhc Posted May 23, 2011 Share Posted May 23, 2011 We always load CVRTs with 4 chains, 2 crossed over on the front towing eyes and 2 on the rear ones. You can see them move down quite a bit on the suspension as you tighten up the chains. Quote Link to comment Share on other sites More sharing options...

You can see them move down quite a bit on the suspension as you tighten up the chains. On a wheeled vehicle straps are normally acceptable but on tracked i would not feel safe with anything other than chains. Infact these days I dont feel safe with anything strapped on without chains. My stalwart once stretched some 5 ton strops enough for it to be basically floating free on the back of the truck. Luckily it was in gear and with the hand brake on and I am a very slow driver when loaded but still very very dangerous. I never moved it again without chains...

cosrec Posted May 23, 2011 Share Posted May 23, 2011 I dont think Robin Craig is saying straps are no good but the way they are being used is wrong eg the strap going over the drive sprocket straps sharp edges (piont loadings)no good. I do agree with using chains on that job would be the easiest simplest solution Quote Link to comment Share on other sites More sharing options...
xtreme Posted May 23, 2011 Author Share Posted May 23, 2011 have you fitted a tacho will eventually be fitting a tacho but for my first test I will be using tacho excemtion form . My chains were at work and need to load the cvrt in the yard so used spanset straps for temp . will have chains on when on the road .

protruck Posted May 24, 2011 Share Posted May 24, 2011 how will you get tacho exemption, its a 1990's vehicle... Hi Paulob1. Not all of the drops vehicles were built in the 1990's. At lest 25 were build before scammells shut in 1988. so it might be an early one?. hope this helps Clive Quote Link to comment Share on other sites More sharing options...

haybaggerman Posted July 7, 2011 Share Posted July 7, 2011 How much will one of these carry? Presumeably a saracen would be happy enough on one? Really nice toys you have by the way, Also, will a foden carry more? Cheers Paul Quote Link to comment Share on other sites More sharing options...
haybaggerman Posted July 7, 2011 Share Posted July 7, 2011 hmmm..... if I'd bothered to look at the Withams site I would have seen that they carry 15 tons. Quite like the look of the fodens and would be a project for next year so might have to hold on and see what develops. Quote Link to comment Share on other sites More sharing options...
