NOTES

  • Column (1): Sufficient particulars must be given to identify the crane or hoist.
  • Column (2): If the jib has a variable radius, test loads must be applied at the maximum and minimum radii.

    "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 regulation 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 the Occupational Safety and Health in Dock Work (No. 152), 1979, adopted by International Labour Conference.

Instructions

Loose Gear
  • Every crane and other hoisting machine with its accessory gear shall be tested with a test load which shall exceed the safe working load (SWL) as follows:
    • Safe Working Load..... Test Load
    • Upto 20 tonnes....... 2 per cent in excess of SWL
    • 20 to 50 tonnes...... 5 tonnes in excess of SWL
    • Over 50 tonnes....... 10 per cent in excess of SWL
  • Lifting appliance other than ship's derricks and winches:
    • The test load shall be lifted and swung as far as possible in both directions. If the jib or boom of the crane has a variable radius, It shall be tested with test loads at the maximum and minimum radii. In case of hydraulic cranes, when owing to the limitation of pressure

      it is impossible to lift test load in accordance with table under paragraph 1, it will be sufficient to lift the greatest possible load.

    • The test shall be performed at maximum, minimum and intermediate radius points as well as such points in the arc of rotation as the competent person may decide. The test shall consist of hoisting, lowering, braking and swinging through all positions and operations normally performed.
    • An additional test shall be made by operating the crane or hoist at maximum working speed with the SWL suspended.
  • Use of spring or hydraulic balance; etc. for test load testing:

    All tests normally shall be carried on with the help of dead weights. Test load testing on new ship shall always be with dead weights. In case of periodical tests, replacements or renewals, test load may be applied by means of a suitable spring or hydraulic balances. In such case, test load shall be applied with the boom as far out as practicable in both directions. The test shall not be taken as satisfactory unless the balance has been certified for accuracy by competent authority within two percent and the pointer of the machine has remained constant at the test load for a period of at least 5 minutes.

  • Testing machines and weights;
    • A suitable testing machine shall be used for testing of chains, wire ropes, loose gears and other cargo gear.
    • Testing machines and balances to be used In test loading, testing and checking shall not be used unless they have been certified for accuracy at least once in the preceding 12 months by Competent Authority.
    • Moveable weights used for the test loading of the lifting appliances having a SWL not exceeding 20 tonnes shall be checked for accuracy by means of suitable weighing machine.
  • Thorough examination after testing of test- loading

    After being tested or test loaded, every lifting appliance and associated gears shall be thoroughly examined to see that no part has been damaged or permanently deformed during the test. For this purpose, the lifting appliance or accessory gear shall be dismantled to the extent considered necessary by the Competent Person.

  • The test and thorough examination must be made by a Competent Person.
