Can one heavy equipment mobile case serve the shop and the field?

Answer: The body can, the fittings cannot. Field work needs lugs and pockets; transfer needs swivel wheels and brakes.

What separates 200 mm wheels from 100 mm?

Answer: Obstacles and push force. The 200 mm wheel clears a 25 mm gap that stops the 100 mm one, and starts 200 kg at 120 N instead of 190 N.

Where does the three-high figure come from?

Answer: A 400 kg lid rating. With eight ribs at 12 mm, the base sags under 1.5 mm after 30 days.

Is a relief valve mandatory?

Answer: Outdoors, yes. A −30 °C to 70 °C swing creates 0.3 bar, and without a valve the lid must be pried open.

How much interference should the insert have?

Answer: 2 mm on 30 mm EVA. Zero will not seat, and 5 mm lets equipment move.

How a Heavy Equipment Mobile Case Is Used: Four Scenarios

Quick answer: A heavy equipment mobile case works in four settings: in-plant transfer, line-side staging, field installation, and warehouse or long-haul stacking. Scenario sets wheels and lugs, load sets wall and base, distance sets how it is towed.

FAQ

1. How Heavy Equipment Mobile Case Scenarios Are Split

Sort use by three facts, not by industry: distance per trip, load per trip, and whether the case leaves the plant. A heavy equipment mobile case rolling 30 m indoors and one crossing 300 m of yard can share a body, never the wheels or the lugs.

Four settings follow: in-plant transfer, line-side staging, field installation, warehouse stacking. Transfer cares about tread wear, field work about lifting and lashing, storage about stacking. A flat warehouse case sent outdoors gets lifted from below, crushing the base ribs.

Scenario	Trip distance	Load	Key options
In-plant transfer	10-50 m	80-200 kg	200 mm wheels, brakes
Line-side staging	under 5 m	50-150 kg	fixed wheels, side door
Field installation	over 200 m	200-500 kg	lugs, lashing, pockets
Warehouse, transit	long haul	over 300 kg	three-high stack, ribs

2. In-Plant Transfer and Line-Side Staging

Transfer is the highest-frequency job: a station beside an assembly line moves a case 40 times per shift over 30 m, so the wheels log 30,000 m a year. The wheel plate fails before the tread, since every turn applies a side load.

Run 200 mm wheels, two fixed and two swivel, for a 1.2 m turning radius; four swivel wheels steer in a narrow aisle but wander when pushed straight. Six M8 bolts into an 8 mm steel plate outlast four by roughly double.

Staging rarely exceeds 5 m, so the case becomes a mobile workstation. A side door asks for 700 mm of aisle, while a lid needs 1.4 m of headroom. On epoxy, 200 kg starts at 120 N; on gritty concrete it climbs past 180 N.

3. Field Installation and Temporary Sites

Outdoors the first need is lifting, not rolling. Four lugs rated 250 kg each cover a 500 kg case with half the capacity in reserve, sitting symmetrically about the centre of gravity.

Forklift pockets of 120×60 mm sit at both sides of the base behind a 6 mm steel sleeve; without it a fork rounds the plastic in a few lifts. The lid takes 150 kg as a bench, and four corner lashing points work against 3 g.

Across −30 to 70 °C the case builds up to 0.3 bar, absorbed by a relief valve set at 0.35 bar. Sealing follows IP67 at 1 m/30 min, and hardware takes 72 hours of salt spray.

4. Warehouse Stacking and Long-Haul Transit

Storage is a stacking problem. A heavy equipment mobile case is built three high, the bottom unit carrying two cases and their contents, with the lid rated at 400 kg.

Eight base ribs, 12 mm high, spread that load; shorter ribs sag after 30 days on the third level, and a base dished by 3 mm never sits flat. Transit adds 10–500 Hz at 1.5 g per axis.

A 30 mm EVA insert with 2 mm of interference holds equipment by rebound and loads faster than straps. Slow movers stack high, labels to the aisle; fast movers stay below 1.2 m.

5. Matching Configuration to Each Scenario

Side by side, the four scenarios collapse to four options: wheel set, lifting hardware, door type and insert.

Option	Transfer	Field	Warehouse
Wheels	200 mm	200 mm, wide tread	100 mm or flat
Lifting	none	four lugs, pockets	pockets
Opening	side door	lid, two latches	lid
Insert	30 mm EVA	EVA plus desiccant	EVA, full wrap
Stacking	none	two high	three high

Conclusion

Splitting scenarios for a heavy equipment mobile case comes down to three questions: how far it rolls, how much it carries, and whether it leaves the plant. Distance asks for swivel wheels and brakes, load asks for lugs and forklift pockets, and outdoor work asks for a relief valve. Fix the scenario first and the heavy equipment mobile case stays the right tool in month one.
