Design Requirements For Crane Spreader

Design Requirements For Crane Spreader
 

The design, manufacturing, inspection, use, scrap, maintenance, and management of the design, manufacturing, inspection, use, scrap, maintenance, and management of the lifts. Including hooks, holding a picker, lifting beams, grabbing, lifting electromagnets, lifting vacuum suction cups, container -specific booths and tests.
 

The design, manufacturing, and use of the spreader and cable should meet the following safety requirements:
 

1. The carrier structure should be simple, clear, direct, direct, and reduce stress concentration;
 

2. The effects of dynamic load, wear, corrosion, temperature, and working environment should be considered during design;
 

3. The loading component should have sufficient strength, stiffness and stability;
 

4. The surface and inside of the bearer should not be sufficient to damage its availability, and there should be good anti -fatigue and the impact skills that meet the actual work needs;
 

5. The method of spreader and cables, and its connection on the lifting machinery should be safe and reliable; if necessary, there should be a protection device or measure to ensure the safety operation of the spreader;

6. Exposure on the possibilities of activities that are injured and possible, should be equipped with a protective cover; the structure used in open -air should avoid water accumulation. measure;
 

7. Structural design should also consider the convenience of manufacturing, transportation, installation, inspection and maintenance;
 

8. The manufacturing method must be suitable for the materials used and meet the design and process requirements;
 

9. Forging fiber direction, it is necessary to conform to the shape distribution of the work;
 

10. The rolling direction and work fiber direction of rolling parts should be consistent with the direction of the stress, and the heat -impact area formed by gas cutting must be eliminated;
 

11. When the forging parts and rolling parts cannot fully meet the performance requirements or are difficult to manufacture, the bearing parts are allowed to use castings, which should generally be cast steel parts.
 

12. Manufacturing materials and outsourcing parts must have technical certification documents such as the manufacturing unit's qualification certificate. Otherwise, it should be tested to find out that it can be used after the performance is qualified.
 

13. After the inspection of the spreader and wicker, the manufacturing unit shall make a marked marking in its appropriate position and issue a qualified certificate. The marking content should include at least: the rated weight (extreme workload), inspection signs, production numbers, manufacturing date, manufacturing unit; the content of the qualified certificate should include the main technical performance parameters; manual;

14. Dedicated scholarships and cables with qualified certificates should be used, and the use unit shall have safe use, maintenance rules or corresponding rules and regulations.
