PTO is Power Take Off... if the truck has a hydraulic system (such as dump trucks, wreckers, roll-offs, etc.), then it has a PTO which engages the hydraulic pump.
PTO is a Power Take Off. It's often used to operate hydraulic systems (e.g., the hydraulic pump on a dump truck).
Need to know who manufactured the PTO system in order to answer this question. It's an aftermarket accessory not manufactured by Freightliner. So, we don't know who manufactured the PTO, what model it is, or what type of actuation it has (e.g., mechanical, pneumatic, or electronic).
International manufactures trucks in classes 5 through 8. How you operate the truck depends on what class of truck it is, what transmission it has, etc. Operating the PTO system to raise and lower the dump bed will also depend on what transmission you have, as well as the PTO system. If you can give a specific model, the answer can be narrowed down.
If you have experience operating a Class 8 truck, you should have the driving part down. If not, I would suggest you go to a truck driving school - you're not going to learn how by simply reading about it. As for the PTO controls, it depends on which PTO system you have. Normally, you push in the clutch, engage the main PTO control, let off the clutch, and use the secondary PTO control to raise and lower the dump body. Some systems differ, however.
You will probably burn out the hydraulic pump in a short time.
Depends on a number of factors, such as make and model, type of dump body, powertrain, material the dump body is made of, PTO system, other attachments, etc. For a tandem axle, on-highway dump truck, you're looking at between 20,000 and 25,000 lbs.
Really depends on who manufactured the body - Freightliner had nothing to do with that. You engage the PTO... depending on the manufacturer of THAT, you can have a PTO or ETO, and they may be actuated either by a lever on the floor, an air switch, or an electrical switch. The outriggers may be operated by hydraulic valves, electric over hydraulic switches, or air over hydraulic levers or a joystick. You're talking about a system which is 100% aftermarket - Freightliner only supplies the chassis - and more specific instructions can't be given without knowing who the manufacturer is and what system it is.
You engage the PTO system, then you actuate the lever to raise the dump body. If you have something like an electrical system (for a one ton pickup), then it's just the push of a button.
The dump truck contains a hydraulically power controlled cylinder that expands as fluid is injected, resulting in the "dump" trailer lifting from the frame of the vehicle. This system is referred to as a PTO, or Power Take-Off.Info:http://en.wikipedia.org/wiki/Power_take-offPhoto:http://img.alibaba.com/photo/209566984/dump_truck.jpg
PTO stands for Power Take Off.
If the dump is run by a pto you can tow it in gear (you said manual trans) with the pto engaged and you should be able to raise the dump box. There is a lift fuel pump in each tank and a high pressure pump on the frame rail below the drivers door area.
