Learn how to load a dry van trailer properly for floor-loaded, palletized, and mixed freight. Covers weight distribution, maximizing cube utilization, securing methods, and avoiding common loading mistakes.
return ( Why Loading Technique Matters A properly loaded dry van maximizes the freight you can carry, prevents cargo damage, keeps you legal on axle weights, and makes unloading faster at delivery.
A poorly loaded trailer leads to shifted freight, damage claims, overweight fines, and wasted space that costs you money on every load.
Whether you are floor-loading boxes, stacking pallets, or handling mixed freight, the same fundamental principles apply: distribute weight evenly, secure the load against movement, and use the available cubic space efficiently.
Palletized Freight Most dry van freight ships on standard 48x40 inch pallets (GMA pallets).
A 53-foot dry van can fit 26 standard pallets loaded straight (two across, 13 rows deep) or up to 30 pallets when turned sideways in alternating rows.
Key considerations: Straight loading (lengthwise): Pallets face the long way (48 inches across the trailer).
This is the standard method and allows forklift access from the rear.
Two pallets side by side fill the 98-inch interior width with minimal gaps.
Turned loading: Alternating rows with pallets turned 90 degrees can squeeze in more pallets but creates offset rows that are harder to unload and may not be accepted by some receivers.
Double stacking: If the product and pallet can support it, stacking two pallets high doubles your load capacity.
Maximum trailer interior height is about 108-110 inches.
Standard pallets are 6 inches tall, so you need product height under 48 inches per pallet to double-stack safely.
Pinwheel loading: One pallet straight and one turned in each row.
Used when pallets do not fill the width cleanly.
Creates a tighter fit but makes forklift access harder.
When a shipper says "26 pallets, no double stack," they mean straight-loaded, single high.
This is the easiest to load and unload.
When they say "floor loaded" or "hand stacked," that means no pallets — boxes go directly on the trailer floor.
Floor-Loaded Freight Floor loading means stacking boxes, cartons, or cases directly on the trailer floor without pallets.
This maximizes cube utilization (you use every inch of space) but is labor-intensive and slower to load and unload.
Common in import/export container transloading and LTL consolidation.
Begin loading at the front wall of the trailer and work toward the rear doors.
This creates a solid wall of freight that supports itself.
Fill each row completely before moving to the next.
Partial rows leave gaps where freight can shift during transit.
Always place heavier boxes on the floor and lighter ones on top.
This prevents crushing and keeps the center of gravity low.
Alternate the orientation of each layer like bricks in a wall.
This prevents the stack from toppling during braking or turns.
Use dunnage, air bags, or cardboard to fill any voids.
Empty space allows freight to shift and creates damage.
