Precautions for mixed installation
When exporting, the main concerns of general enterprises during the loading process are incorrect cargo data, damage to the cargo, and inconsistency between the data and customs declaration data, resulting in customs not releasing the goods. Therefore, before loading, the shipper, warehouse, and freight forwarder must coordinate carefully to avoid this situation.
1. Goods of different shapes and packages should not be packed together as much as possible;
2. Goods that will seep out dust, liquid, moisture, odor, etc. from the packaging should not be placed together with other goods as much as possible. “As a last resort, we must use canvas, plastic film or other materials to separate them.” Cheng Qiwei said.
3. Place light-weight goods on top of relatively heavy goods;
4. Goods with weak packaging strength should be placed on top of goods with strong packaging strength;
5. Liquid goods and cleaning goods should be placed under other goods as much as possible;
6. Goods with sharp corners or protruding parts need to be covered to avoid damaging other goods.
Container loading tips
There are usually three methods for on-site packing of container goods: namely, all manual packing, using forklifts (forklifts) to move into the boxes, then manual stacking, and all mechanical packing, such as pallets (pallets). ) Cargo forklift trucks are stacked in the box.
1. In any case, when the goods are loaded into the container, the weight of the goods in the box cannot exceed the maximum loading capacity of the container, which is the total container weight minus the container’s own weight. Under normal circumstances, the total weight and dead weight will be marked on the door of the container.
2. The unit weight of each container is certain, so when the same kind of goods is loaded in the box, as long as the density of the goods is known, it can be determined whether the goods are heavy or light. Cheng Qiwei said that if the density of the goods is greater than the unit weight of the box, it is heavy goods, and vice versa, it is light goods. Timely and clear distinction between these two different situations is important to improve packing efficiency.
3. When loading, the load on the bottom of the box must be balanced. In particular, it is strictly forbidden to have the center of gravity of the load deviate from one end.
4. Avoid concentrated loads. “For example, when loading heavy goods such as machinery and equipment, the bottom of the box should be covered with lining materials such as wooden boards to spread the load as much as possible. The average safe load per unit area of the bottom of a standard container is roughly: 1330×9.8N/m for a 20-foot container, and 1330×9.8N/m for a 40-foot container. The container is 980×9.8N/m2.
5. When using manual loading, pay attention to whether there are loading and unloading instructions such as “Do not invert”, “Put flat”, “Put vertically” on the packaging. Be sure to use loading tools correctly, and hand hooks are prohibited for packaged goods. The goods contained in the box must be loaded neatly and tightly packed. For goods that are prone to loose bundling and fragile packaging, use padding or insert plywood between the goods to prevent the goods from moving within the box.
6. When loading pallet cargo, it is necessary to accurately grasp the internal dimensions of the container and the external dimensions of the cargo packaging in order to calculate the number of pieces to be loaded, so as to minimize abandonment and overloading of cargo.
7. When using a forklift truck to pack boxes, it will be limited by the free lifting height of the machine and the height of the mast. Therefore, if conditions permit, a forklift can load two layers at a time, but a certain gap must be left above and below. If conditions do not allow loading two layers at a time, when loading the second layer, taking into account the free lifting height of the forklift truck and the possible lifting height of the forklift truck mast, the mast lifting height should be the The height of one layer of goods minus the free lifting height, so that the second layer of goods can be loaded on top of the third layer of goods.
In addition, for a forklift with an ordinary lifting capacity of 2 tons, the free lifting height is about 1250px. But there is also a forklift truck with full free lifting height. This kind of machine is not affected by the lifting height of the mast as long as the height of the box allows, and can easily stack two layers of goods. In addition, it should also be noted that there should be pads under the goods so that the forks can be pulled out smoothly.
Finally, it is best not to pack the goods naked. At the very least, they must be packaged. Do not blindly save space and cause damage to the goods. General goods are also packaged, but large machines such as boilers and building materials are more troublesome and must be bundled and tied tightly to prevent loosening. In fact, as long as you are careful, there won’t be any big problems.
