Calculates boxes per layer, layer count, and total box count from cargo and box dimensions.
Máy tính xếp thùng cá
Estimate approximately how many boxes fit from the kích thước thùng and the available khoang hàng dimensions.
Built for field use with xoay trên sàn, giới hạn xếp chồng, safety margin, a 2D layout preview, and URL chia sẻ.
Check at a glance how many boxes fit in a truck bed or fish hold
Compares rotation and mixed-strip placements
Applies giới hạn xếp chồng and biên % together
Take the kết quả out with CSV, a in memo, and URL chia sẻ
Công cụ này làm gì
Compares no rotation, all rotated, and mixed-strip placement to choose a practical approximate maximum.
Applies a safety margin and giới hạn xếp chồng so you can keep the estimate on the conservative side.
Supports recent-size saving, URL chia sẻ, CSV export, and a printable field memo.
Cách sử dụng
- Enter cargo width W, depth D, height H, and the box width W, depth D, height H.
- Set xoay trên sàn, giới hạn xếp chồng, and biên % as needed.
- Review the số thùng tối đa, boxes per layer, layers, không gian còn lại, and chosen layout.
- Use the URL chia sẻ, CSV, or in memo when you need to take the kết quả into the field.
Ví dụ
Tải thùng cáes into a kei van-sized cargo area
Đầu vào
Cargo 1200 × 900 × 800 mm, box 600 × 400 × 300 mm, rotation on, giới hạn xếp chồng 2, margin 3%
Đầu ra
3 boxes per layer × 2 layers = 6 boxes total, with chiều rộng còn lại, depth, and height shown together.
Pack foam boxes into a fish hold
Đầu vào
Hold 1600 × 1100 × 900 mm, box 520 × 360 × 300 mm, rotation on, giới hạn xếp chồng automatic
Đầu ra
Shows boxes per layer, total boxes, chosen layout, and how the safety margin changes the kết quả.
Terms
Margin %
A safety margin applied to the cargo dimensions to account for tie-downs, hand clearance, curved walls, and other uncertainty.
Stack giới hạn
A manual cap on the number of layers so you can reflect box strength or site rules.
Mixed strip
An approximate search that fills one side in the normal orientation and inserts rotated boxes into the leftover strip.
Leftover space
A practical width/depth/height indicator, not an exact geometric map of the remaining empty shape.
Formulas
Effective cargo dimension = cargo dimension × (1 - biên % / 100)Per-layer count without rotation = floor(W_eff / boxW) × floor(D_eff / boxD)When rotation is allowed, the công cụ also compares all-rotated and mixed-strip placements.Layers by height = floor(H_eff / boxH), then capped by the giới hạn xếp chồng if one is setTotal boxes = per-layer count × layers
Câu hỏi thường gặp
Is this a fully optimal packing solver?
No. It is a field-oriented approximate optimizer. It searches rotation and simple mixed-strip layouts, but not special shapes, fixtures, or full 3D optimization.
Does it judge whether stacking is safe?
No. Box strength and operating conditions vary too much. Use the giới hạn xếp chồng to manage that on the safe side.
How should I account for gaps or fixtures?
Use biên %. It lets you reserve space for tie-downs, hand clearance, ice, curved walls, and protrusions.
Can I turn the boxes on their side?
Yes, in advanced cài đặt. It is off by default because it is easy to misuse. Always confirm stability and product impact on the actual box.
URL chia sẻ chứa những gì?
URL lưu các kích thước và tùy chọn cần để tái tạo cùng kết quả, chẳng hạn như kích thước khoang hàng, kích thước thùng, biên, xoay và giới hạn xếp chồng.
Lưu ý quan trọng
- This công cụ is an estimate. It does not model fixtures, curved surfaces, protrusions, anti-collapse material, or working clearance.
- Leftover dimensions are indicators only and do not describe the exact empty shape.
- Stack safety, tải, slipping, and tipping risk depend on field conditions.
- Make the final decision against the actual khoang hàng and boxes.
