A Power Take-Off (PTO) is a mechanical gearbox that attaches to a truck's transmission and transfers engine power to auxiliary equipment — most commonly a hydraulic pump — through a rotating shaft. Instead of installing a separate engine to run a dump body, crane, or compressor, the PTO lets the truck's own engine do the work.

Where does a PTO mount?

The mounting position depends on the transmission model. On most Hino and Isuzu transmissions the PTO aperture is on the left side of the gearbox, while ZF transmissions place it at the rear. This is why a PTO must always be matched to the exact transmission model — bolt pattern, gear pitch, and aperture position all differ between brands.

What does a PTO power?

A dump truck's hydraulic tipping body is one of the most common PTO applications on Thailand's roads — the PTO drives the pump that raises the bed to unload.
  • Truck tipping mechanisms (dump trucks & tippers)
  • Mobile crane operations and truck-mounted winches
  • Garbage compactors and refuse collection bodies
  • Cement mixers and mobile crushing equipment
  • Airport baggage handling and railway maintenance vehicles
  • Bus air-conditioning systems
  • Fishing vessel winches and marine applications

How to select the right PTO

  1. Transmission model compatibility — the PTO must match your gearbox's aperture and gear specification.
  2. Engagement type — manual cable shift, air shift, or direct engagement.
  3. Mounting position — side or rear, depending on chassis clearance.
  4. Rotation direction — the output flange must turn the same direction your pump requires.
  5. Application — intermittent duty (tipper) vs continuous duty (mixer, blower).
  6. Torque requirement — the PTO must deliver enough torque for the driven equipment, with margin.
