Would a lift of 1200 mm be sufficient for a D4 body off?

Thanks in advance.

You would think 1200mm should be enough. All the videos I have seen look like you only have to lift the body high enough for the hoist lifting arms to clear the wheels. By that stage the front end section of the body would clear the top of the engine, allowing the chassis to be rolled forward.

If reversing the chassis out would need a higher lift than going out forward.







Of course never done it myself - only researched how I would go about it. Hopefully someone like DazzaTD5 can confirm.

So body off at 1200mm, I’m trying to think what the total height is then. I guess it’s around 1900mm normal plus 1200mm, give or take mounting points chassis to hoist.

So 3.2m min likely ceiling required.

It’s an interesting option. May even get away with a 800mm lift if only need to clear the wheels, so then would only need a 2.8m ceiling.

Would still need a minimum 4inch steel reinforced concrete floor at 20MPa.

The specs notes it has a 110-240V AC motor. But does need a 25A outlet.

I presume that’s 25A at 110V so a 15A outlet here in smart land.

That would be good. Their web site though is not very clear on this, and differs from the manual.

Should note it only has a 1,066mm lifting stroke from the lowest position to the highest position.

But the calculator suggests it could lift a D3/D4 body to max height with a 2.8m ceiling. I have used 300mm clearance to the bottom of the body lifting point, and 1900mm vehicle height.

That lifts the body only 868mm, with the first 198mm of stroke to raise the lifting arm to the body. It does have lift pad adaptors to give an extra 76mm total height. Then you could lift the body 944mm but would need a 2.85m ceiling to be safe.



Safety lock position 5 should be high enough for the lifting arms to clear the wheels as this raises the arms 878mm and the body 680mm (when not using the adaptors), but the question then is if this is enough for the front end body section to clear the motor?

You can always remove this front end section of the body and possibly get away with a 2.6m ceiling.

(Edit: checking the dimensions on my D3, the lower section of the front end body frame is about 500mm below the top of the motor - so lifting the arms 878mm and the body 680mm should be high enough to roll the chassis out forward).
