About Power Take OFF


Power Take Off (PTO) systems are essential mechanical gearboxes that attach to truck transmissions. They play a pivotal role in transferring power from the vehicle’s engine to various components, particularly hydraulic pumps in Thailand. PTOs accomplish this by transmitting power through a rotating shaft, enabling the operation of auxiliary equipment that enhances the functionality of trucks and other vehicles.

Mounting and Configuration of PTOs

The placement of a PTO on a transmission depends on the specific model. For example:

  • In Hino and Isuzu transmissions, the PTO aperture is typically located on the left side.
  • With ZF transmissions, the PTO aperture is commonly found on the rear side.


PTOs are utilized in a wide range of applications across different industries, including but not limited to:

  • Truck Tipping Systems: Facilitates the tilting and unloading of truck beds.
  • Airport Baggage Handling Tugs: Powers the movement of baggage carts and trolleys at airports.
  • Garbage Compactors: Enables the operation of compacting mechanisms in waste disposal vehicles.
  • Railway Repair Vehicles: Supports the equipment used for maintenance and repair tasks on railway tracks.
  • Cement Trucks: Assists in operating the mechanisms for mixing and dispensing cement.
  • Mobile Crushing Plants: Powers crushers and screens in mobile crushing equipment for construction and mining.
  • Air Conditioning Drives for Buses: Drives the air conditioning systems in buses and other commercial vehicles.
  • Fishing Trawlers: Supports the winches and other equipment used in fishing operations.
  • Mobile Cranes: Powers the lifting and hoisting mechanisms in mobile crane units.


Selecting the appropriate PTO for your application requires careful consideration of several factors:

  1. Transmission Number: Match the PTO with the specific transmission model to ensure compatibility and optimal performance.
  2. Method of PTO Engagement: Consider whether manual or automatic engagement is preferable based on the operational requirements.
  3. Mounting Side: Determine the suitable side for mounting the PTO based on the configuration of the transmission.
  4. Flange Rotation Direction: Ensure that the PTO’s rotation direction aligns with the requirements of the driven equipment.
  5. Application Usage: Evaluate the intended use of the PTO to determine the necessary specifications, such as speed and torque.
  6. Torque Requirement for Driven Equipment: Calculate the torque needed for the equipment powered by the PTO to ensure sufficient power delivery.
