Marine Order 32 (Cargo handling equipment) - Australian Maritime ...

Test and thorough examination procedures for material handling equipment Schedule 42.2.3 The proof load must be applied:(a) with the derrick boom or crane jib at its minimum working angle (or loadradius in the case of a crane or derrick crane), measured from the horizontalplane and stated in the certificate of test; or(b) in the case of a variable length jib crane, with the jib at its maximum andminimum operating lengths, stated in the certificate of test, and at a lengthapproximately midway between maximum and minimum.2.3 Structural test with movable weightsWhere a crane or derrick is tested with movable weights, after the movableweights are hoisted:(a) the crane or derrick must be swung at slow speed to the extremities of itsslewing arc; and(b) in the case of a jib crane with a travelling capability, the crane must bemoved the entire length of its travelling track at slow speed with the jibextended to the maximum working outreach perpendicular to its directionof travel on one side of its travelling track, and again, with the jib similarlyextended to the other side; and(c) in the case of a bridge or gantry crane with a travelling capability, the cranemust be moved the entire length of its travelling track with the hoist at oneextremity of the traversing span, and again, with the hoist at the otherextremity; and(d) in the case of a bridge or gantry crane without a travelling capability, thecrane must be made to move the weights from one extremity of itstraversing span to the other; and(e) in the case of a derrick crane, in addition to paragraph (a), the derrick craneis to be luffed at slow speed to its maximum operating angle measured fromthe horizontal plane, then returned at slow speed to its minimum operatingangle.2.4 Structural test with spring or hydraulic balanceWhere a derrick or crane is tested with a spring or hydraulic balance, or similarappliance, the proof load must be applied, for a period of not less than5 minutes, at the minimum working angle at each extremity of its working arcand in its midship position.2.5 Operational test of craneA crane must undergo an operational test, including testing of its limit switches,by hoisting a load at least equal to the SWL while carrying out all motionsoccurring in normal operations, such as hoisting, luffing, slewing and travelling,using its full range of speeds. All brakes must be tested in accordance withsubclause 3.3 of this Schedule.2.6 Structural test of derrick gear in union purchaseFor the purpose of testing derrick gear in union purchase, the proof load must bemanoeuvred throughout the working range of the gear, rigged over one side ofthe ship and hoisted to a level that:(a) makes the angle between the runners close to, but not in excess of, 120°, orMarine Order 32 (Cargo handling equipment) 2011 45MO32 modcomp-130604Z.docx
