Offshore Container Sling Inspection And Certification
- May 31, 2017 -

Offshore container sling type

Offshore container sling is a professional lifting tool for off-shore containers that is connected to a container by means of a shackle and fixed to a container lifting ear for lifting a container at sea, usually not removed from the container unless it is to be replaced The

Offshore container sling includes two major types of wire rope rigging and chain rigging.

Offshore container sling includes: main ring, main rope or main chain, child ring, leg rope or leg chain, shackle and so on.

   High-strength chain rigging is a metal chain connected to the rigging, made of high quality alloy steel. According to its form, there are two kinds of welding and assembly; according to its structure are single limbs and limbs. The wire rope rig is made of high strength wire rope and related spreader assembly. The main form is aluminum alloy or alloy steel consolidation, the two prominent features are wear-resistant, high temperature, corrosion resistance, low ductility, the force will not be elongated, its long life, easy to bend, suitable for large-scale , Frequent use of the occasion. Flexible multi-limb, a variety of combinations can improve work efficiency and reduce costs.

Technical Requirements for Inspection of Offshore Container Sling

The inspection period of the sling can not exceed 1 year, and the inspector may require other inspections or tests. When the test is completed, the inspector shall check whether the lifting device is marked as required.

 When the test schedule requires a load test, any non-destructive testing and visual inspection should be performed after the loading test. The shackles that are not attached to the sling should be checked separately, and the shackles and rigging are assembled together with the rigging.

On the offshore container rigging test, summed up the following points for the reference:

(1) must be from the beginning of the raw materials to check, check the raw materials, components manufacturing plant accreditation qualifications, including the quality management system operation;

(2) the testing of raw materials and components, in particular the non-destructive testing of components, there will often be micro-cracks occur in the product lead to product testing;

(3) product identification and traceability inspection, often the product batch number and the certificate does not correspond, so that the quality problems can not be traced back;

(4) to pay attention to the appearance of the entire rigging inspection, especially the rope with lubricating oil, if not handled properly, will make the entire rigging are dirty, in the manufacturing process is also very easy.
