@Wichtelzwerg , when the vehicle spawns the anchor holding the loading mechanism in place is on , but the winch ropes + sliders are powerd off 9 there is a braker next to controls, that enables / disables the rope length adjustment and the slider , to prevent either from continuously use power when not in use

with the best will in the world, but not to use at all.
the sliders fluctuate around a bit at random, without that you can drive them specifically
back and forth. you can set a rope length, which? nothing changes in the ropes with which the containers are suspended.

should i have overlooked somewhere levers or switches that are hidden, which you are also need for the loading, then i ask for explanation.
