This is a standard for couplings and containers for the trucks in scale 1:25. By following this standard, you are ensured that any container will fit onto your trailers and any truck will be able to pull the trailers.
A 2.5 meter wide becomes 12 studs wide in scale 1:25.
There should be at least 9 studs of free space between the trailer knob and the cab of the truck.
The truck is only allowed extend up to 8 studs behind the trailer knob.
The trailer may at most extend 7 studs ahead of the knob.
Behind the knob there must be at least 10 studs of free space.
The following types of wheels and tires are well suited for Model Team trucks in scale 1:25 (and scale 1:22 as well):
The coupling of a truck must latch to a trailer coupling knob consisting of a 2x2 round brick (shown in red) and have a flat surface.
See the building instructions for examples of how to construct latch mechanisms.
In scale 1:25 a 20ft. container becomes 12 studs wide, 30 studs long and 10 bricks tall.
A 40ft. container is 60 studs long.
A forklift can lift the 20ft. container because of the two 2x1 holes in floor of the sides.
A crane can grab onto the 1x2x2 panels in the top corners.
The cheese slopes on the top and cavity beneath ensures interlocking between containers.
