Point foundation

Good evening everyone,

just to make the initial situation understandable.

We have a parking space with a slope of about 30cm over a length of 6.5m. (So quite a slight slope) A caravan is supposed to stand on this parking space, and we want to pull it onto the parking space with a winch. The winch is to be hooked onto an eyelet at the end of the parking space. The caravan will weigh about 1.5 tons, so the hook must be attached accordingly securely.

My idea was the following:

To "cast" a ground anchor like this #link entfernt; Bauexperte into a foundation. For the foundation, I imagined a size of about 50*50*80 cm depth; I wanted to include a handful of rebar to increase the stability. The foundation should protrude about 10-15 cm from the ground so that the later cable does not lie on the ground; I would therefore install formwork in the upper area.

Am I on the right track here? Do I need to use a special concrete? I was thinking of #link entfernt; Epi concrete. Is there perhaps a cheaper alternative to the expensive ground anchor?

Are there important notes or anything else I should know?

I would be very grateful for help, I have been dealing with the topic for a while but am worried about making mistakes.

Archimedes would simply plant an olive tree and use enough redirecting "pulley systems," so you could enormously reduce the force.

JOKING aside

So with 50x50 cm you could probably pull a 50 ton truck. Only rolling resistance needs to be overcome.

Why so complicated?

I would properly park the caravan with the towing vehicle, engage the brake, and additionally secure it against rolling away with wheel chocks.

Archimedes would simply plant an olive tree and use enough pulleys, which could significantly reduce the force.

Just as a side note, a pulley reduces the required force, but the weight pulling on the tree/anchor remains the same...

Just to mention, with a pulley the required force is reduced, the weight pulling on the tree/anchor remains the same...

Well, the force is only reduced on one side with a pulley (the required pulling length is correspondingly increased), the total force at the anchor/"target" remains the same.

from on the go
