NOTES

• Column (2): The dimensions of the loose gear the type of material of which it is made and where applicable, the heat treatment received in manufacture should be stated (unless Form No. VII is used for the purpose).

  "Competent person" means.-

  • a person belonging to a testing establishment in India who is approved by the Chief Inspector for the purposes of testing, examination or annealing and certification of lifting appliances, loose gears or wire ropes;
  • any other person who is recognised under the relevant regulations in force in other countries as competent for issuing certificates for any of the purposes mentioned in sub-clause (I) for implementation of the Protection Against Accidents (Dockers) Convention (Revised), 1932 (No. 32) and the Convention concerning Occupational Safety and Health in Dock Work (No. 152), 1979, adopted by International Labour Conference.

INSTRUCTIONS

• Wire rope shall be tested by sample, a piece being tested to destruction, and the safe working load of rope is to be determined by dividing the load at which the sample broke by a co-efficient of utilisation determined as follows:
  

  • S.W.L. (in tonnes)	Text Load (in tonnes)
    Upto 25.	2 X Safe Working Load (SWL)
    Above 25	(1.22 X SWL) X 20

  • In the case of a single sheave block, the SWL shall be the maximum load which can safely be lifted by the Block when suspended by its head fitting and the load is attached to a rope which passes around the sheave of the block and test load not less than four times the proposed safe working load shall be applied to the head of the block.
  • In the case of a multi-sheave block, the test load shall not be less than the following:
    

    SWL (in tonnes)	Test Load in tonnes
    Upto 25	2 X SWL
    Above 25 to 160	(0.933 X SWL) + 27
    Above 160	1.1 X SWL

  • In case of hand-operated pully blocks used with pitched chains and rings, hooks, shackles or swivels permanently attached thereto, a test load not less than 50 per cent in excess of the safe working load shall be applied.
  • In the case of a pully block fitted with a bucket, the bucket shall be tested and the test load applied to the bucket while testing that block will be accepted as test loading of the bucket.
  • In the case of a sling having two legs, the safe working load shall be calculated when the angle between the legs is 90. In case of Multi-legged slings, the safe working load shall be calculated as per the national standards.
  • Every lifting beam, lifting frame, container spreader, bucket, tub and other such gears shall be subject to a test load which shall not be less than that given in table below:
    

    Safe working load (in tonnes)	Test load (in tonnes)
    Upto 10	2 X SWL
    Above 10 to 160	(1.04 X SWL) + 9.6
    Above 160	1.1 X SWL

  • • Before any text is carried out, a visual inspection of the lifting appliances or loose gear or lifting devices involved shall be conducted and any vitiable defective gear shall be replaced or renewed.
    • After being tested, all the loose gear and other such gears shall be examined. All the sheaves and the pins of the pulley blocks shall be removed to see whether any part has been injured or permanently deformed by the test.
• The test and examination must be made by a competent person.
• The test must be made by Competent Person.
