Why not make the 6.0 mm wheel plate as thin as the wall?

Answer: The Wheeled Military Transport Case carries 20 kg stacked six high, and the wheel seat is a point load a 5.1 mm wall cannot take; thickening the plate alone to 6.0 mm keeps settlement within 0.9 mm after six layers / 24 h. The material saved by equal thickness buys no stacking margin.

What readings move if the R12 mm guard radius is cut smaller?

Answer: A smaller radius pushes the upper wheel-seat load back onto a sharp corner, so corner stress rises after six layers sit 24 h and settlement grows by more than 0.2 mm; in the off-centre round the chance of one guard denting first also climbs.

At how many layer counts is settlement recorded?

Answer: Two, four and six layers are each logged for the Wheeled Military Transport Case, with the 24 h value taken as final; both 8.6 kg empty and 20 kg loaded states are run and the larger settlement is kept, without averaging.

Can the 3.6 kN compression replace the 1.2 m drop?

Answer: No, the 3.6 kN compression probes whether the mouth and plate crush under off-centre load while the 1.2 m drop probes whether the plate root and floor part, and the Wheeled Military Transport Case clears only when both pass; the settlement remeasure must stay within 0.1 mm of the stacking value.

Wheeled Military Transport Case

Quick answer: The Wheeled Military Transport Case pairs a 6.0 mm wheel-mount plate with an R12 mm corner radius, holding six-layer settlement at 0.9 mm and 3.6 kN.

FAQ

1. Wheel-mount plate thickness of the Wheeled Military Transport Case

The Wheeled Military Transport Case keeps a 6.0 mm wheel-mount plate under its base, thickened rather than an extension of the 5.1 mm wall. Between a 680 x 480 x 300 mm envelope and a 605 x 415 x 230 mm cavity, spare material goes to the wall, the mouth flange and this plate. At 20 kg stacked six high, an equally thin plate would drive the wheel-seat bolts into the floor.

The 6.0 mm value is sampled at six points, each within 0.3 mm of nominal. The Wheeled Military Transport Case logs the thinnest point, since settlement starts at the lean corner. Plate thickness governs vertical support and the R12 mm guard radius sideways force, so both readings share one card for the six-layer / 24 h stack.

Plate tier	Measured plate	Wheel-seat settlement after six layers / 24 h
Thin	4.8 mm	1.3 mm, reject
Nominal	6.0 mm	0.7 mm
Thick	7.2 mm	0.5 mm

2. Corner radius of the mouth guards

The four mouth corners of the Wheeled Military Transport Case take an R12 mm radius so the load above slides down a curve instead of pressing a sharp point. Guards share axes with the wheel plate, letting an upper wheel seat land on the lower arc crown. Cut the radius too small and corner stress after six layers / 24 h adds over 0.2 mm to settlement.

An R12 mm arc absorbs the slight outward bow of a 20 kg loaded mouth better than a right angle does, versus 8.6 kg empty. Before the Wheeled Military Transport Case reaches the stacking rig it runs 4300 empty open-close cycles, then stacks six high. Four latches at 455 N each are checked in that run; cycles with the lid not fully seated are excluded.

3. Settlement readings layer by layer under stacking

Stacking of the Wheeled Military Transport Case follows six layers / 24 h, with wheel-seat height measured after each layer and a final reading at the full 24 h. The 0.9 mm ceiling governs; the first three layers climb fast and the last three flatten, so the record is the 24 h value, not any rebound. Both 8.6 kg empty and 20 kg loaded states are run, keeping the larger settlement.

The rig clamp drifts about 0.05 mm at zero, so JUNZHIJIA subtracts that play before the Wheeled Military Transport Case records settlement, in a separate card column. Corrected layer curves show which layer crushed the plate and which only loosened tooling. Six layers matches the loading ceiling behind the 3.6 kN compression check.

Stack layers	Cumulative load time	Wheel-seat settlement
2 layers	8 h	0.3 mm
4 layers	16 h	0.6 mm
6 layers	24 h	0.8 mm

4. Compression judgement under off-centre load

Beyond even stacking, the Wheeled Military Transport Case clears an off-centre round: the upper shell shifts about 60 mm so load falls on two guards on one side, and compression must hold 3.6 kN. A 1.2 m drop follows, landing opposite a guard so shock runs down the arc into the base. The 3.6 kN compression and 0.9 mm settlement are separate lines; a shell clears only when both pass.

At the 1.2 m drop retest the plate roots are checked for blushing, then settlement remeasured; a gap over 0.1 mm from the stacking value means the plate and floor parted. Mouth sealing of the Wheeled Military Transport Case is checked after both figures are in: an IP67 spray retest sees whether the two gaskets at 23 percent compression still meet. The spray covers the mouth alone.

5. Plate-thickness rejection line for wheeled batches

Eight shells per batch are measured at the plate, and for the Wheeled Military Transport Case a reading 1.0 mm under the 6.0 mm nominal is a reject; two such shells send the whole batch back, with no single good shell released alone.

The line matches the thinnest plate holding settlement within 0.9 mm after six layers / 24 h. Go thinner and the sixth layer lifts the reading near 24 h. Mould temperature, hold time and this line go into the JUNZHIJIA process card, and a tool or material change calls for one more full run. The Wheeled Military Transport Case binds each settlement reading to its release decision, filed by shell number. The batch code matches only that shell's data. The table below sorts three bands into outcomes, so a retester does not treat the thick tier's margin as a batch-wide tolerance.

Settlement value	Matching plate tier	Disposition
no more than 0.9 mm	nominal 6.0 mm	release
0.9 to 1.2 mm	thin 4.8 mm	remeasure wheel seat
above 1.2 mm	reject band	whole batch rework

Conclusion

A 6.0 mm wheel plate paired with an R12 mm guard radius is what lets the Wheeled Military Transport Case hold wheel-seat settlement within 0.9 mm and compression at 3.6 kN after six layers / 24 h, with the off-centre and 1.2 m drop retests covering joint loosening. Measured plate, layer curves and the rejection line are filed in tiers by JUNZHIJIA and rerun after any tool or material change. When specifying a wheeled shell of this kind, ask first whether plate thickness and corner radius come with measured figures.
