Wire and cable products need to go through a certain process of transportation and storage from the factory to delivery to the user. During this period, they need to go through many times of handling, loading, unloading and storage. Some wire and cable factory is good, but to the hands of customers, the cable appearance has been damaged, some wire and cable insulation has been damaged, these problems occur from time to time, should cause everyone's attention. Commonly used wire and cable into a circle or on the plate for the packing and shipping, in transport, the problem should be paid attention to the following aspects: 1, wire and cable transportation before should first check whether the cable packing is in good condition, cable certificate whether fill in the specification, the cable end head is tightly, and firmly fixed on the cable, cable tray lateral plate are loose and fall off wait for a phenomenon, after confirmed no problem, can transport. 2, wire and cable tray should be generally used forklift or crane, loading and unloading cable tray, it is strictly prohibited to lift several cables at the same time, because such lifting, several cables force uneven, unstable center of gravity, prone to slip and fall. 3. The cable tray is not allowed to be loaded, unloaded or stored on the flat side, because the flat side will loosen the cable winding and affect the normal wiring of the cable, and the flat side may also damage the cable and cable tray. 4, in vehicles, ships and other means of transport, cable tray should be crisscrossingly arranged, cable tray must be placed firmly, both sides of the wire rope firmly fixed in the vehicle, and at the bottom of the cable tray with triangular wedge plug, prevent the cable tray shaking, collision or overturned during transport. 5, cable rolling on the ground must be according to the direction indicated by an arrow on the scroll on the side of the cable, if the direction of rolling, will make the cable unwinding and loose, not when the cable protection plate rolling, highlight the outermost layers on both sides of the plate must be the cable more than 10 cm, can prevent hard objects when rolling pressure below the cable, so as not to damage the cable. Cable tray rolling should be controlled in a small range, long distance movement must be used forklift or crane and other special equipment. 6, cable car, it is strictly prohibited to cable directly push from the transport vehicle, the large cable hoisting machinery or tripod to manual gourd, smaller cable (or plate) only a small amount of cable can into slope wood planks, with a rope or control of the winch cable, slowly down along the slope, prevent cable rolling when subjected to mechanical damage. 7. For important engineering cables or export cables, protective plates should be nailed to the cable tray for opening. The protective plates should be tightly packed and fixed. 8. When the cable is mounted, the end shall be sealed reliably. Protective cover (cap) shall be added to the cable end extending out of the disk. 9, large cable tray transport, should pay attention to the choice of road transport equipment, if the use of truck transport, should pay attention to the height of the car should conform to the traffic road bridge, culvert and other height restrictions, if exceed the limit, can use a special trailer, in order to reduce the height of transport. 10. Do not throw the coil loaded wires and cables when they are moved. Handle and put them gently in transportation to avoid mechanical damage. Loop flexible line can be stowed or transported in the container, stacking height should not be too high, stacking between close contact or good fixed measures, in order to prevent stacking collapse, damage cables. After the cable is transported to the destination, it should be checked in time to see if there is any cable damage. If there is any cable damage, it should contact the manufacturer immediately and be solved by the manufacturer. The damaged cable should not be put into use to prevent adverse consequences.
