What about dual circuit on the prime mover plus trailer brakes?

In the "Pink Bit" of post 232205 it mentions "3 independent brake systems, including exhaust brake".

Often wondered just what was the advantage of the inverted ram set up?
Seen a few short-ass pig and dog trailers set up with them, mostly rigid piping bolted to frame with flexible hoses where they tip over the axle and where they have quick connectors at the coupling.
Effort required would be the same, whether your pushing up or down on the ram, I would have thought?
Another mystery of life, I guess, just someones different application?

If the seals work properly there is no reason not to install them “upside down.” It is often more important that the hoses are protected and have minimum flex than other considerations. Also the cylinder is usually provided with a much more substantial mount than the rod end. This is a primary consideration in a lot of circumstances. Because of these two reasons, you will see that hydraulic cylinders are mounted in different positions on things like backhoes and excavators. These machines use a number of cylinders and the hoses are usually the most fragile parts of the machine. They must be protected from damage caused by the function of the machine and are mounted in the “best” fashion and the upside or downside is not relevant.

Yeah, that makes sense, see a heck of a lot of large excavators often with multiple ram set up, have rigid piping bolted to frames with flexible hosing only on the pivot points.

When you see pictures of new trucks tipping,you dont realise that the rams can take terrific side loading keeping the front of the body from going over sideways...........there are lots of utubes of tipping trailers going over sideways.....even seen one blown over by the wind

Some rams I have on machinery have one hose going straight in near the pin on rod and the through the rod to fill the ram
The other end on the other end on the cylinder

They seam to work fine with no problems at all

I would be think the main advantage of having a ram mounted up side down is the dirt wont land on seal and damage it

Leylands used to have triple circuit air brakes ...........just another stupid idea the Poms had ............Strange thing is none of thse idiots who make these rules realized that you can run out of brakes if you dont adjust regularly..........in fact with maxis ,a truck that runs out of brakes has zero maintenance.............but what catches a lot of lazy people is the maxis run out of travel a bit before the foot brakes .
