Fluid Power Products and Accessories Supplier: Power Take-Offs (PTO) and their Applications

Blog | May 17th, 2023

A Power Take-Off, or PTO, adds adaptability to a truck’s normal cargo transport duty. It sends electricity to auxiliary equipment to accomplish tasks on-site or en route.A power take-off (PTO) can eliminate the need for a second or auxiliary engine to power the equipment. It adds efficiency to any vehicle transportation application, including dump trucks, garbage trucks, snow vehicles, etc.

Here are pieces of information to help you understand how a PTO operates and to help you learn more about it.

What Exactly Is a Power Take-Off?

A power take-off is a gearbox that distributes power from the engine and transmits it to auxiliary equipment via spinning the PTO gears and meshing the vehicle transmission gears. The power is generated by the truck’s engine and is utilised to power the vehicle application’s equipment.

Factors That Influence How Rapidly a Power Take-Off Spins

The speed of the PTO output is determined by its internal gearing and the transmission’s internal ratio to the PTO driving gear. For PTO functioning in an automatic gearbox, the minimum input speed must be higher than the torque converter lock-up (unless the transmission allows “live drive,” which means the PTO is driven through the impeller). PTO output speeds might be less than, higher than, or equal to transmission speeds depending on the internal gearing.

Role Of PTO Horsepower (Hp) And Torque Play In Selecting A PTO

We must determine the needed input horsepower of the driven machine. Horsepower is a measure of work capability per unit of time. Torque is the amount of effort necessary to twist or spin anything. The horsepower is factored into the calculation to get the torque required for the appropriate PTO.

The Difference Between A Hydraulic And A Mechanical Shift Power Take-Off

Independent PTOs are classified into mechanical (i.e. 489 series) and hydraulic (i.e. new 210 series). A clutch mechanism is used to engage a hydraulic shift PTO. Traditional (torque converter) automatic gearboxes use hydraulic shift PTOs. A mechanical shift PTO activates by physically changing one gear onto another. This is often accomplished with a lever, cable, or air pressure. PTOs with mechanical shifts are used in manual and automated manual gearboxes.

PTO Maintenanceon A Daily And Weekly Basis

Periodic PTO maintenance is critical for the appropriate, safe, and trouble-free running of the PTO.Before using the PTO daily, inspect all air, hydraulic, and functioning mechanisms. Maintain the system as needed.Check for suspected leaks monthly and tighten all air, hydraulic, and mounting hardware as needed. Torque all bolts, nuts, and other fasteners to Chelsea specifications. If appropriate, ensure that splines are adequately lubricated. Maintain the system as needed.

Other Common Applications of PTOs

Agricultural Equipment

PTOs are commonly used in agriculture for powering equipment such as mowers, balers, and ploughs. The PTO is connected to the tractor and powers the equipment.

Industrial Equipment

PTOs are also used in industrial equipment such as generators, pumps, and compressors. The PTO is connected to the engine and powers the equipment.

Construction Equipment

PTOs are used in construction equipment such as backhoes and excavators. The PTO is used to power the hydraulic systems that operate the machinery.

Marine Applications

PTOs are used in marine applications such as boats and ships to power equipment such as winches, cranes, and pumps.

In summary, PTOs are versatile mechanical devices that transfer power from an engine to other machines or equipment. They have many applications in agriculture, industry, construction, vehicles, and marine industries.
