FatCow posted:Real trucks only. I don't have a pic with the trailer on it. So why are you guys all posting pictures of cars then?   Work truck- 33,000lb in the truck, 5500lb in the trailer, 7700lb in the backhoe on the float. If it aint got air brakes, it aint a truck.

angryrobots posted:That trailer is too short for regularly carrying that size backhoe. And the ramps don't have knees? That's an accident waiting to happen right there. Yeah it's not that machines regular float- we had a massive pipe burst in the middle of another park we had to fix right now and the regular float was off getting the brakes serviced so we just used the bobcat float instead for the 5km journey. It's also a "never unload this machine unless it's connected to a truck" float too The squat in the rear of the truck is because it's been parked and not run since the backhoe was loaded so it hasn't reset the rear air bags to level itself out with the tow hitch down weight- the trucks gvm is 15T and GCVM is 28T and we've got enough freeboard to allow for ball down weight in the truck. And yeah, it's government which means it's 100% by the book or not done at all with vehicles- the arse kicking you get for not being legal isn't worth taking any risk at all- it WILL cost you your job!

Yeah, the airbag systems pretty impressive on the MAN trucks- As you use the water in the truck (its a fire truck we use for works) the airbags bleed air off to keep the truck at a set level, same as you fill it, it adds pressure to keep it level too. Drop a trailer on, system registers the extra weight, increases the pressure and because it knows how many psi/kg it takes to compensate for weight, it knows exactly how much weights over the back axle, and tells the transmission to change its shift patterns to allow for it. its got a ZF 12 speed Ztronic trans, which is a 12 speed manual with auto clutch and auto shift, and it will take off in a higher gear and skip shift its its lightly loaded, or if its right up at the heavy end, it will start really low and work through every gear to get up to speed. The floats pretty drat old and doesnt have hydraulic lift on the rear ramps, so they have to be built a lot lighter than one with hydro lift. The float doesnt tilt, but you can jack the back of the truck up by about 8" to tilt it using the airbags. We also tend to use 2500kg webbing ratchet straps instead of chain binders- they have a bad habit of you reefing the poo poo out of them, getting them tight as a bastard and going for a 2 minute drive to see ones gone loose and popped open. Ratchet straps are really idiot proof and with 2x straps at the front and 2x straps at the back youve got 10,000kg of lashing capacity (not break strain) holding your poo poo down. Never heard of holding down a loader arm- you see spare trenching buckets in a backhoe being restrained but thats about it. Excavators and that will get the bucket and arm on a low loader lashed down, but that because its a standard to stop the drat thing rotating itself out into traffic! And if your in a government vehicle here without a load properly restrained and you get caught, its a breech of the public service code of conduct (thou shall not unnecessarily endanger your employers!), which can get your arse fired and black listed from ever holding a government job again too.
