分步裝載指南
規劃起重機進出與吊裝順序
開頂裝載需謹慎規劃起重機作業。確定貨物將透過艙門(通常使用叉車)裝載、從頂部(起重機)裝載,或兩者兼具。提前預訂起重機容量——您需要一台起重機,其工作半徑與起重能力足以應對最重單件貨物。規劃裝載順序,使由起重機裝載的物品優先裝入(這些物品將位於底部或後部),而由艙門裝載的物品最後裝入。
檢查貨櫃、防水布與頂棚橫樑
檢查貨櫃主體結構是否完好,特別是承載防水布負荷的頂部側軌。檢查可拆卸的頂棚橫樑——它們必須牢固鎖定於正確位置。檢查防水布是否有撕裂、破洞與繫索環損壞。確認所有防水布張緊繩索與扣具均完整且功能正常。防水布損壞將導致貨物受潮——拒絕任何防水布有缺陷的貨櫃。
使用起重機裝載超高貨物
拆除頂棚橫樑與防水布後,使用適當吊索或橫樑從頂部吊入貨物。優先放置超高物品,左右居中以確保穩定性。若貨物高度超過側軌高度(2.33公尺),則被歸類為超限(OOG)貨物,並將在船上產生附加費與特殊固定要求。確保起重機作業期間貨物不觸及或損壞側軌。
保護貨物免受天氣影響
與標準貨櫃不同,開頂貨櫃在裝載、港口儲存或任何防水布拆除期間,貨物將暴露於雨水與海浪飛沫中。在裝載前用防水布包裹敏感貨物。對於機械與金屬製品,應塗抹防鏽劑並使用VCI(揮發性防鏽劑)包裝。切勿假設防水布本身能提供充分的防水保護——它僅是次要屏障。
將貨物固定於繫固環和側欄桿
開頂式貨櫃在頂部側欄桿上設有額外的繫固點,專門用於固定超高貨物。使用重型棘輪帶或適用於貨物重量的鏈條。貨物必須在六個方向(前、後、左、右、上、下)固定,防止移動。對於超出欄桿的OOG貨物,請與承運商協調特定船舶的固定要求。
重新安裝防水布、密封並記錄文件
將頂部橫樑正確復位,並將防水布鋪設在頂部。均勻拉緊所有繩索和扣具——鬆弛的防水布在運輸過程中會拍打並撕裂。確保防水布與側欄桿完全重疊,無縫隙。盡可能從上方(如可行)和門端拍攝已裝載貨櫃的照片。精確記錄OOG尺寸——承運商需要精確的尺寸進行船舶配載規劃。
Weight distribution rules
重心貨物需置中以確保吊車穩定性
使用吊車裝載時,重型物品應盡量置於縱向中心附近。與從門側裝載(由前至後)不同,吊車裝載的物品會被放置在吊車所及的任何位置。偏離中心的重型物品在其後續吊裝過程中會導致危險的不平衡。
固定防止上浮——無頂蓋
標準貨櫃的頂蓋可防止向上移動。開頂貨櫃則無結構頂蓋,僅有防水布。頂部較輕的物品必須綑綁固定,而非僅靠擠壓固定。海上航行期間的強風可能極為猛烈,任何未固定的物品都可能被吹出貨櫃。
計算超高貨物重量對欄杆以上部分的影響
若貨物高度超過側欄杆的2.33公尺,欄杆以上部分的重量會產生額外的傾覆力。向承運商提供確切的超高尺寸與重量。船舶配載計劃人員需據此數據分配正確的艙格與綑綁配置。
考量吊車衝擊下的地板載重限制
使用吊車降下貨物時,觸地瞬間的動載荷可能達靜載荷的1.5至2倍。將此衝擊載荷納入地板載重計算。使用木質墊材分散機械腳的集中載荷,並始終輕柔降下貨物——切勿任其自由墜落。
Loading Patterns Library
Optimize your container space with proven loading patterns for different cargo types
Column Stack Pattern
A simple and straightforward loading pattern with boxes stacked in vertical columns. Ideal for uniform cartons with good stacking strength.
Best For
- • Uniform, rigid cartons
- • Boxes with good stacking strength
- • When load stability is a priority
Efficiency
Pro Tips
- • Ensure columns are aligned vertically to maximize weight-bearing capacity of boxes
- • For added stability, consider plastic wrapping each column or adding corner protectors
- • Leave minimal gaps between columns to prevent shifting during transport
Interlocking Pattern
An advanced loading pattern where each layer alternates orientation, creating a more stable structure. This "brick-like" arrangement distributes weight more evenly and prevents collapse.
Best For
- • Cartons with moderate stacking strength
- • Medium to long distance shipping
- • When preventing collapse is critical
Efficiency
Pro Tips
- • Alternate the orientation of each layer by 90 degrees for maximum stability
- • Ensure boxes can support this load pattern - weaker boxes may crush despite interlocking
- • Creates better resistance against shifting during transit, reducing damage risk
Pinwheel Pattern
An efficient pattern where boxes are arranged in alternating orientations within the same layer, creating a pinwheel-like appearance. This maximizes space utilization and provides excellent stability.
Best For
- • Rectangular boxes with non-square dimensions
- • When maximum space utilization is needed
- • Shipments requiring both stability and efficiency
Efficiency
Pro Tips
- • Works best when box length is roughly twice its width (2:1 ratio)
- • Can improve stability and prevent shifting compared to simple stacking
- • For heavier goods, limit stack height and consider layer separation with slip sheets
Cargo Securing Techniques
Proper cargo securing is essential for safe and damage-free transport. Learn best practices for different cargo types and conditions.
Lashing & Tie-Down Techniques
Proper cargo lashing prevents movement during transport, reducing the risk of damage and ensuring safe delivery. Container ships can experience significant forces during transit, making secure cargo essential.
Understanding Lashing Points
Standard shipping containers come equipped with built-in lashing points in the floor, walls, and ceiling. These anchor points are designed to secure cargo with straps, ropes, or chains.
- • Floor lashing points can typically handle 2,000-5,000 kg of load
- • Wall and ceiling points usually have lower capacity (1,000-1,500 kg)
- • Always check the specific lashing point capacity in your container documentation
Effective Lashing Techniques
Diagonal Lashing
Straps run diagonally from the cargo to the lashing points, creating tension that prevents movement in multiple directions.
Loop Lashing
Straps form loops around the cargo and attach to lashing points on the same side, providing lateral stability.
Cross Lashing
Straps cross over the cargo in an X pattern, providing excellent stability against both lateral and longitudinal forces.
Direct Lashing
Straps connect directly from the cargo to the nearest lashing point, offering simple but effective restraint.
Pro Tips
- • Always use lashing points on opposite sides to create balanced tension
- • Check strap tension periodically during loading to account for settling
- • Use edge protectors where straps contact cargo edges to prevent damage
- • For heavy cargo, combine multiple lashing methods for redundancy
Essential Tie-Down Equipment
Lashing Straps
- • Breaking strength: 2,500-10,000 kg
- • Available in various lengths
- • Typically made of polyester
Tensioners & Ratchets
- • Working load limit: 500-5,000 kg
- • Look for smooth ratchet operation
- • Choose appropriate size for strap
Hooks & End Fittings
- • Claw hooks for lashing points
- • J-hooks for various attachments
- • Safety latches prevent disengagement
