The Load That 'Just Fits'
An order for 30 pallets is booked on a 53-foot dry van with a 26-pallet floor footprint, a 44,000 lb cargo weight limit, and 110 inches of usable interior height. Twenty-two pallets are 60 inches tall and cannot be stacked. Eight are 40 inches tall and may be double-stacked. Every pallet weighs 1,450 lb. The customer's receiving window is tomorrow, 08:00-11:00; a missed window pushes delivery out four days and triggers a $2,500 chargeback. The carrier's only alternative trailer is already committed to another shipper. LTL is available at $310 per pallet with a two-day transit. The load planner says the shipment 'just fits.'
1. Verify or refute the planner's claim. Show the cube and weight math.

Cube
- 22 non-stackable pallets = 22 floor positions
- 8 stackable pallets = 4 floor positions (40" + 40" = 80", under the 110" limit)
- Positions used: 22 + 4 = 26 of 26 - the trailer is exactly full, with no reserve.
Weight
- 30 x 1,450 lb = 43,500 lb against a 44,000 lb limit - a 500 lb (1.1%) margin.
Verdict: the claim is arithmetically true but operationally unsafe to rely on. The load has zero cube slack and 500 lb of weight slack. Any overweight pallet, damaged pallet needing a slip sheet, load bars, or a pallet jack riding along blows one or both limits. A load that only works if nothing goes wrong is not planned, it is gambled. Confirm actual pallet weights from a scale ticket before dispatch, and identify two pallets now that can be pulled if needed.
2. At the scale, the driver reports the tractor drive axles 1,200 lb over and the trailer tandems 600 lb under. What are your options and what do you do?

The gross weight is legal; the problem is weight distribution, not total weight. Options in order of cost:
- Slide the trailer tandems rearward to transfer weight off the drive axles onto the trailer axles. Iterate one hole at a time and re-scale; verify against bridge formula and axle ratings, and confirm the kingpin setting is legal for the states on the route.
- Re-sequence the load so the heaviest pallets sit over the trailer axles rather than at the nose or the tail. With 26 positions fully occupied this is limited, but usually sufficient for 1,200 lb.
- Pull freight. Remove 2 pallets (2,900 lb) and move them LTL at $620 total.
Decision: attempt 1 and 2 with a re-scale before the driver leaves the yard. Never dispatch overweight - it is a legal violation, voids cargo coverage, and puts the whole $2,500 chargeback at risk anyway. If the re-scale is still over, pull the two pallets and ship them LTL. $620 is cheap against $2,500 plus a four-day delay.
3. If the fix pushes pickup past the customer's receiving window, what is your decision rule?
Read the worked answer
Rank options by total cost and by customer impact, not by internal convenience:
- Call the customer immediately and ask for a later window the same day. Receivers often have flexibility if asked early; the chargeback usually applies to no-shows and late arrivals without notice, not to a same-day re-book.
- Split the shipment legally. Deliver the compliant portion inside the window and the balance LTL. Partial receipt at $620 incremental beats $2,500 plus four days of lost availability.
- Hold and consolidate only if the customer agrees and the downstream effect is nil - otherwise you trade a $620 freight bill for a $2,500 penalty.
Non-negotiable: do not dispatch an overweight or unsecured load to protect a window. The exposure is legal liability and a denied claim far larger than the chargeback. Escalate the carrier commitment failure separately - a single committed trailer with no backup is the root cause here, and the lane needs a documented contingency.
