Thank you for your answers!
I have measured the narrowest spots of our driveway, there it is 2.90m, so it should fit a container truck, even though it’s tight! In advance, I send pictures of the driveway with the measurements to the respective container company, or they should come and measure themselves. It is supposed to be a simple 10sqm container for parking, these roll containers would probably be too long for our purpose.
The truck would only have to reverse straight in.
The Iveco 3.5-ton truck with box body/hydraulic loading ramp, e.g. from our company, has the following dimensions: The box is the widest, rigid part with exactly 2.00m width, with extended mirrors it would be a total of 2.60m width.
That pleases me already, since I often borrow this truck to deliver larger equipment and material.
