What is the difference between the side-mounted PTO and the sandwich PTO for the Water bowser truck?

The sandwich power take-off is a full power take-off, which is installed in the middle of the engine and the gearbox, and can borrow all the power of the gearbox.

Generally used for fire water tanker, high-pressure cleaning vehicles and other models, and special vehicles that require high-speed power will be used.

The side-mounted power take-off is a small power take-off, which is installed on the side of the gearbox and can only take part of the power of the gearbox.

It is generally used in water bowser trucks, detachable garbage trucks, sewage suction trucks and other models, as well as special vehicles that require low-speed power.
