When is a plastic tote the better buy than a Transit Case?

Answer: Dry goods, moves inside one workshop, no sealing, no high stacking. Add a wet season and the loss wipes out the saving.

What does the extra money buy over a wooden box?

Answer: The gasket and the latch hardware. Wood wins on payload and price; the case wins on 900 cycles and IP65.

Can a steel rack replace it?

Answer: Indoors on a fixed route, yes. Outdoors, no: it is open on four sides.

When does single-use packaging come out cheaper?

Answer: One-way despatch with no return leg, on low-value goods.

How should cost per turn be calculated?

Answer: Purchase plus lifetime repair, divided by actual cycles, with downtime separate. Count cycles on the weakest part.

Transit Case vs Alternatives: Where the Differences Sit

Quick answer: Put a Transit Case beside plastic totes, wooden pallet boxes, steel transfer racks and single-use packaging, and unit price tells you almost nothing. Cycle counts differ more than tenfold, so the comparison only works per turn.

FAQ

1. Comparing a Transit Case With Four Alternatives

Ranking five options by price is the first mistake: price covers the first trip, and these units live for years.

Option	Price	Cycles	Per turn
Transit Case	820	900	0.91
Plastic tote	90	260	0.35
Wooden pallet box	460	90	5.10
Steel rack	2,100	1,500	1.40
Single-use pack	35	1	35.00

The cycle column is the one people skip, and structure sets it. A tote goes brittle after two summers outdoors; a wooden box needs re-nailing after a few impacts.

2. Turnaround Speed: Loading and Handover Time

Speed splits into loading, handover and opening; the slowest tells you what to fix.

Transit Case: a grey case open on white, lid lined with black foam, base foam cut for circuit boards, wires and two round lenses

Loading is per pallet. Twelve units take 6 minutes by forklift, or 14.4 carried one at a time. A Transit Case and a wooden pallet box both make a full pallet; totes stack three high, adding 4 minutes.

Handover: forty units scanned as one code take 4 minutes; the same forty in wooden boxes, whose stencils wear off, take 9 with lids open. At 60 batches a month that is 60 hours a year.

Opening reverses the ranking: a tote lid lifts in 2 seconds, a steel rack takes 15, a latched case about 6, a wooden box 40, shrink wrap 90.

3. Sealing and Stacking: Weather Limits and Layer Height

Sealing decides where an option can stand: a tote is open, a wooden box has joints near 3 mm, a steel rack is open on four sides, single-use film fails once torn, and a case with a parting-line gasket reaches IP65.

Six hours outdoors separates them: the sealed case stays dry with legible labels, totes collect water, wooden boxes pulp their labels.

Stacking is geometry, not strength. Totes hold 3 layers at 60 kg per pallet, wooden boxes 4 at 500 kg, racks 6 at 800 kg, single-use packs 2 at 120 kg, and the case 5 at 180 kg. Six rack layers put the top tier at 1.9 m; anything under 8 kg empty goes over in a force 6 gust.

4. Repair and Retirement: What Fails First

Each option fails somewhere else, and repair method moves cycle count more than the datasheet.

Transit Case: an orange case open on a wooden bench, lid foam cut into square pockets, spanners, cable and clips alongside, grey bins behind

A Transit Case fails at the latch: one set per 150 openings, 35 each, swapped on site in five minutes. Wooden boxes fail at the boards, re-nailed every 20 trips for 15. A cracked tote is scrapped whole, and at 3% monthly breakage a third of the fleet turns over in a year. Racks fail at welds, 120 to repair with two days out.

Downtime is the invisible item: a 12-unit pallet idle two days loses two turns, which for the rack is 240 in hidden cost. Plastic scrap returns 2.4 per kg, so a 7.8 kg case gives back 18.

5. Cost per Turn: Spreading the Price Over Cycles

Add purchase, repair and downtime, then divide by real cycles.

Option	Price	Repair	Per turn
Plastic tote	90	0	0.35
Transit Case	820	210	1.14
Steel rack	2,100	120	1.48
Wooden pallet box	460	60	5.80
Single-use pack	35	0	35.00

The tote wins on paper, with limits: dry, short distance, no sealing, no stacking above three. One wet season removes the 0.79 gap, because a single 3,000 yuan pallet load ruined pays for three cases.

Wooden boxes cost most per turn and still own the half-tonne load. Racks repay their price over 1,500 indoor cycles.

Conclusion

None of the five is simply better; each maps to a duty cycle. Totes win on price and speed, wooden boxes on payload, racks on life, single-use on having no return leg. A Transit Case sits above the middle: only where sealing, stacking and frequent opening coincide does its cost per turn flatten out.

Spread the price over every turn: on that basis a Transit Case is rarely the cheapest, and usually the one that fails least.
