When specifying an Industrial Protective Case by scene, what comes first?

Answer: The handling method. Push, lift or hoist sets the base and handles.

Is there a stacking limit for transfer cases?

Answer: Three high; the grooves are eight millimetres deep and the walls are rated for it.

Why cut the insert two millimetres over the outline?

Answer: To absorb equipment tolerance and foam compression; tighter will not load, looser rattles.

What lid angle suits a maintenance bay?

Answer: 105 degrees. It self-holds and clears the walkway; shallower bays want a side-opening lid.

Does an outdoor station need IP67?

Answer: If rain pools around the case, yes. IP67 covers half a metre for thirty minutes.

Industrial Protective Case Applications: Scenes and Setups

Quick answer: An Industrial Protective Case earns its cost in four places: transfer inside the plant, shipping with equipment, maintenance bays and outdoor stations. Each sets different demands on size, insert and handling, so choose the scene first.

Transfer: size and handling
Shipping with equipment: inserts and documents
Maintenance sites: lid angle and reach
Outdoor stations: rating and mounting
FAQ

1. Four places an Industrial Protective Case is used

Sorting an Industrial Protective Case by scene beats sorting by volume: the same 520 by 340 opening is a transfer unit in a shop, an accessory box at a builder, a bench for a crew.

Scene	Internal size, mm	Load and handling	Key feature
Transfer	520 x 340 x 180	20 kg, cart	stacking grooves, ribs
Equipment	400 x 300 x 150	8 kg, in crate	EVA insert, doc pocket
Maintenance	600 x 400 x 220	25 kg, two-person lift	lid stop, layered insert
Outdoor	700 x 450 x 300	30 kg, vehicle or hoist	IP67, moulded-in nuts

Transfer takes about half of demand, equipment and maintenance a fifth each, outdoor the rest.

2. Transfer: size and handling

Stacking, not volume, is the first constraint. The lid of an Industrial Protective Case carries four grooves eight millimetres deep that seat on bosses in the base, so three high will not slide. Above three, the lower walls carry over a hundred kilograms; a wall under three millimetres will bulge.

Industrial Protective Case: a closed olive green case on a workshop floor, one latch and a folding handle, scuffed corners, blue racking behind

Twelve pieces at 1.6 kilograms make 19.2 kilograms, near the limit for repeated one-person lifting; heavier needs a cart. Cut the interior to piece count with two millimetres of clearance: enough to lift out in gloves, not enough to rattle.

3. Shipping with equipment: inserts and documents

Here the case is part of the machine, not its packaging; insert tolerance matters more than wall strength. An EVA cavity is cut two millimetres over the outline, with thirty millimetres of base foam and twenty-five of egg-crate in the lid.

Item	Practice	Dimension	If skipped
Cavity	EVA routed	outline plus 2 mm	unit shifts
Base foam	thicker under pockets	30 mm	bottom impact
Lid foam	egg-crate	25 mm	lid does not seat
Documents	pocket in lid	A5	paperwork lost

Documents need a fixed home: an A5 pocket in the lid for manual, certificate and spares list, plus a 90 by 60 millimetre label area. Three insert revisions a year on two hundred units keeps the cutting file moving.

4. Maintenance sites: lid angle and reach

A maintenance bay judges the case after the lid opens. The lid of an Industrial Protective Case stops at 105 degrees and holds without a hand; past that it blocks the walkway. The open footprint is 1.2 times the closed one, so a bay under 1.2 metres wants a side-opening insert.

Reach is arranged in layers: spares at the bottom, tools in the middle, small parts on top, each with a two-finger gap. Laying the case flat and bending for every part halves throughput, and a three millimetre ABS sheet in the lid turns the closed case into a bench.

5. Outdoor stations: rating and mounting

IP67 means thirty minutes at half a metre of water without ingress; the compound is rated for minus twenty to sixty degrees, and below minus fifteen the wall goes brittle, so drop height falls from 1.5 metres to one.

Four M8 nuts in the base take bolts through a truck bed or scaffold and hold the case in wind; straps lose forty percent of their strength in half a year of sun. A UV stabiliser keeps colour shift within three units after 500 hours of xenon testing.

Feature	Transfer	Maintenance	Outdoor
Base	ribbed, flat	rubber pads	M8 nuts moulded in
Insert	divider or none	three layers	moisture barrier foam
Handle	side handles	side handles plus rest	lifting eyes
Sealing	standard	standard	IP67 with valve

Conclusion

An Industrial Protective Case is worth what its configuration matches, not what its wall thickness suggests. Transfer lives on stacking and base structure, equipment shipping on insert tolerance and document pockets, maintenance on lid angle, outdoor work on rating and moulded-in mounting. Put the scene first and the specification has a reason. An Industrial Protective Case picked by size alone is rarely worn out early; it is awkward every day.
