Steel tracked units or steel spike wheels.
- Steel tracked units must be driven on rubber mats to ensure a safe operation. This should be arranged by the stevedoring.
- Steel tracks and metal wheels/rolls must be resting upon rubber mats once in final stow position. Units can be driven without rubber mats on flat RoRo decks without any projecting lashing fittings like D-rings etc.
- Units with steel spike wheels:
- This type of cargo must be approved for type of handling on a case-by-case evaluation via Regional operational Quality.
- Evaluation is to conclude allowance for discharge as a self-propelled unit in Port of Discharge. Information on weight, dimension and type of spike are needed to evaluate if the unit can be accepted as self-propelled cargo.
- As an alternative to self-propelled handling, the cargo maybe accepted as static cargo, loaded on a cargo carrier.
- Spiked units can cause damage to terminal ground and vessel decks when loaded as self-propelled cargo.
- Units with spike wheels should be loaded on main deck when accepted as self-propelled and shifting, during the voyage, of the unit is to be avoided.
