How the M-6 Twin Car Rack is used

A sixteen-foot main-deck pallet moulded for car-rack attachments, so two vehicles travel in one pallet position.

The racks are a certified ULD part on their own under code VRA, supplied in pairs at 130 kg. Two limits apply: 8,900 kg for the loaded pallet, and 1,800 kg for whatever sits on the upper rack.

Cargo it usually takes

  • Cars and light vehicles
  • Motorcycles
  • Prototype and show vehicles

How this family is arranged

  • A main-deck pallet with moulding that takes the car-rack attachments.
  • The support racks are supplied in pairs and are themselves a certified ULD part under code VRA.
  • The same system is available for longer vehicles on a twenty-foot pallet. The only change is the pallet empty weight, at 500 kg (1,102 lb).
  • A main-deck pallet base with moulded points for the rack attachments.
  • Support racks come in pairs, so a second vehicle can travel above the first.
  • Wheel restraints and lashing points are built for vehicle loads.

Why operators pick it

  • Two vehicles share one pallet position.
  • The racks are a certified ULD part on their own, so each shipment does not need its own engineering.
  • The same system is available on a longer pallet base for larger vehicles.

Settle these points before you book

  • The vehicle on the upper rack has its own weight limit, separate from the pallet total.
  • Vehicles must be drained and disconnected to meet dangerous-goods rules.
  • Some aircraft accept centre loading only.
