Container loading with mixed boxes, pallets and pipes

Volume is only the first limit

A container can reach its payload before it is full, or run out of usable floor and door clearance while nominal CBM remains. A useful plan therefore checks each item's external dimensions, permitted orientation, quantity and unit weight against the chosen equipment.

Mixed loads are harder because cartons may rotate freely, loaded pallets generally remain upright and long pipe or profile bundles consume continuous length. Treat each handling unit as it will actually be lifted and secured.

Reference equipment

Published container dimensions are nominal references and can vary by manufacturer and fleet. Confirm internal length, width, height, door opening, maximum gross mass, tare and payload on the carrier's equipment specification before booking.

• 20 ft dry: useful for dense cargo and smaller lots.
• 40 ft dry: more floor length, but not double the payload.
• 40 ft High Cube: extra internal height for lighter or taller cargo.

Worked mixed-load sequence

Start with long, orientation-restricted bundles, then loaded pallets, then cartons that can fill residual spaces. Enter net cargo weight for every unit. Review the planner's first-container net weight and remaining payload as quantities change.

If an item is shown as unpacked, check door clearance, permitted orientation and whether its bundle dimensions represent the real transport unit. Splitting one large bundle into two smaller handling units may improve fit, but only if safe lifting and lashing remain possible.

What software cannot certify

A geometric plan is not a loading, lashing or dangerous-goods certificate. It does not replace checks for floor point loads, center of gravity, axle distribution, moisture, ventilation, segregation, blocking, bracing or safe unloading order.

• Confirm the carrier's verified gross mass process.
• Have competent personnel approve securing and handling.
• Keep heavy cargo low and distribute weight deliberately.
• Recheck the plan when packaging or equipment changes.
