What it does
Pick a trailer or truck body and a pallet size, and the planner tells you how many pallets fit on the floor, draws the trailer from above, and checks the total weight against the payload. You can stack pallets and see whether the stack is too tall.
It is a quick planning aid for quoting and loading. Once you know how many pallets fit, load profit shows whether the load pays, and engineering unit converter helps if a size comes in different units.
How to use it
- Choose the trailer or body. The inside length, width, height and payload fill in; change any of them to match your own body.
- Choose the pallet size and type the height and weight of one loaded pallet.
- Choose a pattern and how many pallets high you stack.
- Read the count, the picture and the weight line.
What each setting does
- Straight, long side along the trailer: every pallet points the same way, long side lengthwise.
- Straight, long side across: the long side runs across the trailer. On a 100 in wide trailer, two 48 in pallets fit side by side with the 40 in side lengthwise.
- Pinwheel: searches the best mix of both directions. Pallets turned the other way show in grey.
- Stacked pallets: multiplies the floor count. A warning shows if the stack is taller than the inside height.
Worked example
A 53 ft trailer is 636 in long and 100 in wide inside. With 48 x 40 in pallets with the long side along the trailer, 2 fit across (2 x 40 = 80 in) and 13 fit along (13 x 48 = 624 in): 26 pallets on one level. Turn them so the 48 in side is across and 2 fit across (96 in) and 15 along (15 x 40 = 600 in): 30 pallets. At 1,200 lb each, 26 pallets weigh 31,200 lb, under a 45,000 lb payload.
FAQs
Why does the pinwheel not beat the straight pattern here? On a narrow body the straight “across” pattern is already the best. Wider bodies can gain from mixing.
Are the India sizes exact? No. They are typical inside sizes marked as estimates. Measure your own body.
Does it leave room for loading? No. Real pallets need small gaps, so keep a pallet or two in hand.
Where the numbers come from
- US trailers: 53 ft and 48 ft long, about 100 in (2.54 m) wide and 110 in high inside, payload about 45,000 lb. Typical figures that vary by builder; check your own trailer.
- India bodies (20, 22, 24 and 32 ft): typical inside sizes and payloads, estimates only. Pallets: 48 x 40 in (US), 1200 x 800 mm (EUR), 1200 x 1000 mm. Drawing and layout search are fibub's own.
