Problems needing attention in the transportation of frame wooden boxes

The side and end of the frame wooden box are combined with the box shelf and secret box board of the frame structure, and the chassis is a wooden box made of sliding wood structure. The frame wooden box is a large wooden box. The maximum weight and outer dimension of its contents are determined according to the usual transportation conditions. Shanghai wooden box points out that, generally speaking, the outer length of frame wooden box is less than 12 meters, the outer width is less than 3.5 meters, the outer height is less than 3.5 meters, and the inner weight of frame wooden box is less than 500-20 000 kg. This kind of wooden box is mainly used to pack large mechanical products, but also can be used to pack small goods. Frame wooden box is also composed of base, side, end and top cover. Their structural differences are as follows: the boards of frame wooden boxes are vertical boards: the boards of frame wooden boxes are outside, and the skeletons are all arranged in the boxes; the boxes of frame wooden boxes are assembled by first installing two sides on the base and two sides, and finally binding the top cover; both are loaded on the base, but the boxes of frame wooden boxes are more at the end than sliding wooden boxes. There are more frame structures on the surface and side. It is precisely because of these frame structures that frame wooden boxes can bear much more load than sliding wooden boxes.

Frame wooden boxes can be divided into type I (inner frame wooden boxes) according to their structures: frame members are inside the boards, which are suitable for general internal contents; type II (outer frame wooden boxes): frame structures are outside the boards, which are integral in the long direction and have enough rigid internal contents. The basic provisions of its design take into account the generally anticipated circulation conditions such as transportation, handling and storage.

Shanghai Packaging Wooden Box Manufacturer will tell you about the problems that should be paid attention to in the transportation of frame wooden cases.

Problems in the transportation of frame wooden boxes:

1. Contamination of packing boxes caused by unclean means of delivery. If coal, fertilizer, pesticide and other substances have been carried, the goods transported again will be damaged or polluted if the vehicle is not cleaned in time.

2. The absence of Gabon cloth during transportation causes rain and sunshine, which also causes damage, fading and aging of packing boxes. During transportation, especially long-distance transportation, Gabon cloth must be used to prevent rain and sunshine.

3. Damage to wooden packing boxes caused by improper loading methods, such as:

There are gaps between cargo and cargo, resulting in collision and friction between cargo in the course of transportation.

(2) Inversion of loading goods causes leakage of liquid in the contents to immerse and contaminate other packing boxes.

(3) The improper stacking of the goods on the means of transport causes the overload of the underlying goods and the damage of the packing boxes. In addition, in the process of transportation, commodities also come from the vibration of vehicles, trains, ships, aircraft and so on, so corresponding measures must be taken.

In addition to the above points, we should also pay attention to:

1. If the center of gravity of the wooden box (steel belt wooden box) is low, and the large wooden packing box can only be packed in one layer and can not make full use of the bottom area of the box, it should be placed in the center of the container, and the bottom transverse must be fixed with square wooden bars.

2. If a small wooden box is encountered in a loading process, the seam loading method can be used to make the upper wooden box press on the joint of the lower two wooden boxes, and the top one must be fixed or tightened.

3. If it is a small wooden packing box, if there is a large gap at the end of the box door, it must be fixed or tightened with wooden boards and strips.

4. In most cases, the center of gravity of wooden cases is relatively high. It is not enough to fix them only by the bottom, but also by using wooden strips to support them.

5. When loading large wooden containers with special heavy loads, centralized loads or eccentric loads often occur. Therefore, special fixtures must be provided to prevent cargo from contacting the front and rear end walls of containers.

6. When a frame wooden box is used for a device, it is usually tensioned by steel bands or replaced by elastic nylon or cloth bands.
