it was requested, so here it is, the race-lorry build!

considering the fact i only need it for lorry wheel nuts, i can live with that :D  just wasnt worth buying a maHOOOSive torque wrench...

That’s quite tight! Even tighter than 3 grunts and fart!

when i was doing the brake pads, i managed to damage one of the air hoses to the handbrake spring chamber. whilst i was at Hydroscand getting a length of 10mm plastic hardline, i decided to get the bits together for the accessory air setup i've had in the list of things to do since christmas.

i bought about 10m of hardline (£60 but its nice to have plenty of spare.) a T adaptor and a 10mm to 1/4" male fitting. then i went on amazon and picked up a 24v solenoid with a 1/4" bsp female inlet and outlet. and bent up a bracket out of 2mm aluminium. the result of which...

I50PSVD.jpg

i ran the 2 wires into the junction box i use for the tail lift controls then i ran a feed from under the dash in the cab all the way back and into the junction box also.

i also picked up a twist to release emergency stop button so i mounted that just above, wired it as NC (normally closed which means you push the button in to break the connection) and ran that wire into the j/b also

i then ran a good earth wire down through the floor to the tail lift control box where i bolted it to a good earth.

the air feed to all this is teed into the secondary air system, ran along the nearside chassis leg and up through the floor, all inside corrugated wire conduit to protect it. basically the same as the factory :D

wiring it is rather simple, one wire on the solenoid connects to earth (either one, doesn't matter) the other wire connects to one side of the switch, the other switch leg to the power wire that i ran to the cab.


at the cab end i took the plug off the back of the rear working light switch and tested it. it turns out the connector is not fully populated so i use spade connectors in lieu of the correct pinning kit.

far right pair are the illumination wires, these are pinned into the back of the factory connector.
second from the right is +ve from the fusebox (more on that later) and far left is the feed to the solenoid. i used both brown and blue to avoid voltage drop as much as possible. 


then there was the feed to the switch. i wanted it to be on the accessory side of the battery protection system, same as the tail lift.

i have for a while wanted to tidy up the 'bodybuilder' feeds from the solenoid that is controlled by the battery protect system, both the hazard warning light circuit and the tail lift where using in line fuses straight from the solenoid. the problem is, they are in such a stupid place, you have to take half the dash out to get to them!. anywho, the tail lift is on the accessory side of the isolator the hazards are on the battery side (i guess the reason for that is so the hazards work if battery guard kicks in, big surprise, they don't, cos the bcem isn't powered!) i might one day wire it up as it came out of the factory. but probably not...

after pulling the dash apart i started trying to work out what fuses in the fuse board where unused acc feeds, it turns out there are some, (see across the top here
eqSad2K.jpg

but they aren't pinned, so no go there. 

so what i did was cut the in line fuses out, extend the wires up to the fuse box and slot them in along the top of the fuse box, then run the feeds back down to where they originally were wired in. the tail lift fuse wire, instead of running to the tail lift switch, now runs to the solenoid switch
hrDhOQo.jpg

where as you can see i used a piggy back spade to split the feed to the tail lift switch also.

 that's the switch im using for the solenoid

and the end result...

all that lot took WAY longer than it should have because i spent most of my afternoon chasing why the solenoid only fired occasionally, turns out the earth to that junction box wasn't very good, so a new earth run down to the chassis of the lorry, and all is well.... :D

oh the tangled webs we weave....

 


i am royally peed off with fighting with ramps, then ramp extensions, and still having issues with rampover and dragging the nose up the ramps. there's no point in this lorry if its going to be harder work than just driving it there.

idea 1, a proper car tail lift. not happening. just way out of budget, (8-10k!) so......

i'm going to cut the chassis and beavertail it.

this means losing the tail lift, which is a mixed blessing, it won't have any use after as per the lorries primary purpose, but it was nice to have in case i needed to pick up machinery etc. oh well, needs must.

the photo below is a very crude drawing of what i want the end product to achieve.

the key for the pic is as follows.
the green line shows the new outline of the body, the new floor, as you where
the red line is where the chassis gets cut and welded
the blue is the ramp which gets hinged up against the back of the lorry for transport
the yellow is a channel that will be hung from the floor to hold the ramps in when stored away. to pieces (per ramp) of 50mm angle should do.

pretty crude, but i think you get the idea...

unsurprisingly i've had several people question weather it is legal to cut and weld the chassis, and if so, how to do it.

MAG and Tig are allowed. MAG is preferred. ( where as mig is argon or helium gas MAG is co2/argon mix (usually) . therefore people that call welding with a wire feed welder with co2/argon mix (the most common) MIG welding, are mistaken its MAG welding...) anywho i digress.

so mig welding a chassis is fine, and according to the bodybuilder manual, this is what you are allowed to do...

so no issue then :D

I totally get the ramp thing - nice air system BTW - but before starting to cut up the chassis etc, have you considered converting th tail lift ?

We had a client with the same issues and he modified a Dhollandia lift into a  3,5 mtr. pair of ramps and that took a 100" racer OK...

Just a thought..

car weighs 1300kgs tail lift is rated at 1000kgs measured 500mm from the columbs. still, i was optimistic so i bolted the ramps to the tail lift, added ratchet straps as tensioning wires and tried. didn't even leave the ground.

 

man maths say i need a 4000kg tail lift to be safe.

hmm....

kooiaap to help ?

The racing teams use those ramp lifts all the time - wonder how they do that then...

They’ll just be a more powerful version.

I'll try to reach that client and ask what they did to lift theirs.

Would it not be economically more suited to source a stronger tail lift from a breaker's yard?

It just seems to me that all that cutting and welding, the, the bodywork and finishing is going to amount to a lot more in terms of time/cost than a used lift and overhaul of the lifting gear.

theyre all multiple thousands plus fitting. plus loler certification. it works out at £5-10k minimum

Why does it need LOLER certification if its private?

which would take the chains over their rated capacity, and i really dont want to go there....

I'm surprised your 500kg lift tops out so low. Iifted some stupid stuff with 500kg lifts - including a Ginetta and an 86" Hard top.

I've regularly off loaded/loaded 1 and 1.2 tonne pallets with them as well

Are you sure it's not because the previous operators were less than kind?  Not doubting, but just looking for options

lol previous owners where hovis, i mean, how hard can it be worked lifting a few loaves of bread :rofl:  

 

no, i dont think theres anything wrong, i just think the bypass is cutting in at 1ton , and the car weighs more than that, so...

 

it will lift just the front of the car fine, it really is just a weight issue.

I have to deal with Hovis on a regular basis - mainly a rat control issue. So I've seen how their drivers treat the wagons...😲

spent this afternoon taking the tail lift off. never to be refitted... probably.

i suppose i might put it back on, but only if i can work out how to fit the lights and ramps without them hitting the tail lift.

not actually that hard. 2 wires and one hydraulic hose disconnected, the lights unbolted, the welds cut where its welded to the box body, then undo the bolts down the columbs (yet to do) undo the bolts across behind the ram, then the ones to the chassis, and remove...

bit rusty here...

that will come off fully tomorrow morning.

then the drive home. not normally worthy of a mention on here. except.

there i was, approaching a mini roundabout, when i saw a car approaching the junction to my left. sure enough, she (its usually a she) pulled out in front of me. 

no drama, i was half expecting it so i had plenty of room to stop, so i firmly applied the brakes, the car slows... then the pedal drops to the floor :shock:

i swerve round the front of her and pull over. after replacing my underwear, i realise i've burst a brake hose, the car has twin circuit brakes so it will still stop so as im about 1/8 mile from home, i gingerly make my way home... 

that was fun... :D

O/S/F wheel..

so ill be needing a new brake hose, unfortunately neither ECP or Halfords have one (if ECP don't, halfords wont, ECP supply halfords) amd nowhere else is open tomorrow.

so it seems, ill be loading a generator and a load of tools into the RX8 tomorrow for my trip over to the lorry......

inconvenient, to say the least.!
