Quality Inspection

Before truck delivery, we can supply an inspection certificate issued by a third party such as BV or Intertek - so you verify the tractor head's condition independently before it ships.

Spare Parts Supply

Quick-wearing parts ship with the truck delivery. All parts are produced by the truck manufacturing factory for genuine quality, and we only charge cost price for customer convenience.

One-Year Warranty

Free warranty for one year on the 3 major components - engine, gearbox, and axles - covering the parts that matter most on a prime mover.

After-Sales Tracking

Email and phone tracking for each truck on a timely basis, with possible engineer maintenance in the customer's country - support that follows the tractor head after it leaves the port.

Nude or Wax-Coated Packaging

The tractor truck head ships nude or with a polished wax coating depending on your preference - wax protection against salt spray for longer ocean transits.

Rolling or Bulk Transport

Rolling transport (Ro-Ro) or bulk cargo transportation is used depending on the destination port - the tractor is driven on or lifted aboard, no disassembly required.
