1. Are carton expansion or manual placement gaps simulated?
Container corner castings are 10×10×10 cm. How do you reasonably simulate carton expansion or manual placement gaps?
I. All cartons (or mostly cartons with a few wooden/iron boxes) — manual loading
- If cargo dimensions are real-measured (or cargo loaded directly after production), and the container is standard internal size (20GP: 589×235×239 cm; 40GP: 1200×235×239 cm; 40HQ: 1200×235×269 cm), use one of two methods to simulate manual placement gaps.
1) On the Container interface, set the reserved size. Suggested initial values:
20GP: reserve 5–8 cm length, 3–5 cm width, 3–5 cm height.
40GP: reserve 10–15 cm length, 3–5 cm width, 3–5 cm height.
40HQ: reserve 10–15 cm length, 3–5 cm width, 3–5 cm height.
2) On the Loading-rules interface, set a reasonable placement gap between cargo items.
For cargo in cartons with theoretical dimensions and stored in a warehouse for over a week before shipment, account for expansion due to stacking pressure. Per Japanese expert tests, deformation is about 1%–1.8% of the original size.
If cargo dimensions have been enlarged 1–2 cm already, the reserved size and placement gap need not be set.
If the container size has been reasonably reduced, the reserved size and placement gap need not be set.
II. All wooden/pallet/iron boxes (no or very few cartons) — forklift loading
On the Container interface, set the reserved size. Suggested initial values:
20GP internal: deduct 5–10 cm length, 3–5 cm width, 10 cm height.
40GP/40HQ: deduct 13–15 cm length, 3–5 cm width, 10 cm height.
When the container's height is deducted by 10 cm, set the corner-casting size to 0 (the 10 cm casting is already absorbed).
