Edit: You need to drop the vehicle weight down to 6 tons to use any jack. This is not correctly modeled at all.
The vehicle is a 9ton armored car, I had ‘replaced’ 2 of the broken armored wheels (of the 4… somehow it drove), in order to drive it over to a safe area.
Also the repair an armored wheel with another only took a wrench, it should also require a jack, so that is also broken.
This means there is currently no way to remove any roller drums or tires from a trailer. Short of a lot of time in dropping the weight.
There are all kinds of jacks, bottle jacks can go upwards of 40+ tons.
If I had six or eight tires, I would hardly need to even jack the vehicle as the others would hold up the vehicle fine as the deflated tire could be removed. Which would probably be the case of the roller drums. The others could easily hold it up and you could roll 1-2 off.
Tires share the weight, not 1. This is why a 2 ton jack for the average car/suv is fine. even if the SUV weights more than 2 tons. (many do)
last note: I set my Mass Units as lbs. Why do jacks display as kg? Hmmm lack of consistency there
