PTO Applications

Having explored the function, types, and technical specifications of Power Take-Offs (PTOs), let's look at where they are commonly used and the support systems available to ensure their successful implementation and operation. PTOs are vital components in a diverse range of demanding industries, powered by reliable products from reputable manufacturers.

Real-World Application Examples

PTOs demonstrate their value across numerous heavy-duty applications:

• Rock Crushers: For decades, PTOs have been a cornerstone in rock crushing equipment, including jaw, cone, and impact crushers. They typically operate in a side-load configuration, using sheaves and belts to achieve the necessary speed reduction from the engine to power the crusher mechanism. The PTO's disconnect function is crucial for safety, allowing the crusher to be stopped independently of the engine, especially during jams. Heavy-duty designs, like straddle bearing PTOs, are often favored due to the high side loads and shock forces inherent in crushing operations.
• Irrigation Pumps: Agriculture relies heavily on PTOs to power large irrigation pumps. These systems draw water from sources like rivers or wells to supply center pivots, lateral pivots, or drip irrigation networks. The PTO transmits power from a stationary diesel engine to the pump. The disconnect feature is highly valued, enabling pump shutdown without stopping the engine and, critically, facilitating easier engine starts on cold mornings by removing the pump load during warm-up.
• Wood Chippers: From small, mobile units to large industrial machines, wood chippers almost universally utilize PTOs. The PTO connects the diesel engine to the chipping drum or disc, providing the necessary power while offering the essential safety disconnect. Their robust design handles the intermittent shock loads typical of chipping operations.
• Tub Grinders: Used in forestry, composting, land clearing, and agriculture, tub grinders process large volumes of wood waste into mulch or grind hay for animal feed. The PTO drives the large rotating tub or rotor. In these applications, PTOs are appreciated not only for the engine disconnect but also for their ability to absorb significant shock loads if the grinder encounters tramp metal or suddenly stops, protecting the engine from potentially damaging forces.
