Interesting to see a Japanese-brand Kubota mini digger working in Germany! Skilled operator made it look easy, but he was very controlled and deliberate.
Sweet bit of driving, it must be possible to do that without marking the road, just a couple of pre placed small bits of plywood, or better two bits of reinforced rubber mat (conveyor belt)
For those thinking this might be hard on the machine, the stress on the machine is actually very low when doing this, because it’s only supporting the machine weight, and that’s balanced. There are not even any shock load, the forces are all nice smooth and straight. (no twisting) This may look dramatic, but when an excavator bucket is digging into stone or hard ground (called tear out) the normal tear out forces will be at least 3 times more than ever occur doing this and the biggest risk is actually the digger or the truck driver making a mistake with the controls. This task is not for a novice, but its quite easy for any normal operator who is unlikely to get this wrong. Compared to some digging applications, eg working on slopes its actually relatively easy for any experienced operator to do this. In respect of the machine. If a machine is ever being overloaded a relief will open and the machine either wont lift or will slowly lower until the pressure reduces. For example if something heavy the machine can barely lift is picked up close in and then the boom and dipper are extended out the machine protects itself (all brands) This is because all hyd circuits on any machine brand have a locked line relief valve designed in (called an Auxiliary relief valve or ARV) in each circuit to protect the rubber hoses from force multiplication (burst pressure) if the machine was anywhere near to being stressed the ARV ( safety valve )
I see so many videos of this maneuver. Everyone seems to think that it's an absolutely crazy thing to do but really, self loading or unloading is not that uncommon or even very hard to do.
