Schedule 4Test and thorough examination procedures for material handling equipment(b) such lesser angle as is specified in the drawing or drawings specified inSchedule 7,and again, with the gear rigged over the opposite side of the ship.2.7 Thorough examinationFollowing testing of a crane or derrick, the crane or derrick and all accessorygear must be thoroughly examined by a competent person for damage orpermanent deformity, and overload limit switches reset.3 Winches3.1 Span gear winchesIf a derrick is fitted with a span gear winch, the winch must be tested while thederrick is supporting the proof load at its lowest working angle by in turnsubjecting each sprocket to the resultant load.3.2 Topping and main winchesOn completion of the tests with the proof load, each winch must be tested with aload equal to the SWL suspended from the derrick head, and the derrick placedin various positions such that each winch serving the derrick is subjected toloading while having the maximum working length of rope layers upon its drum.3.3 Brake test of winchesAfter completion of the proof load tests of a derrick, a load equal to the SWL forthat derrick is to be hoisted then, with the derrick slewed outboard to each sideof the ship and with the derrick amidships, lowered at the normal loweringspeed of the winch for a distance of approximately 3 m. The winch is then to bebraked sharply and the load brought to a halt. It is then to be demonstrated that aload equal to the SWL of the derrick can be held stationary by the winch brakewhen the winch drive is switched off.4 Cargo lifts and mechanical ramps4.1 Proof loadWhere a cargo lift or mechanical ramp is tested, the proof load must be not lessthan the applicable load specified in Table 2.SWL of lift or ramp (tonnes)Table 2Proof loadNot more than 20 SWL x 1.25More than 20 but not more than 50SWL + 5 tonnesMore than 50 SWL x 1.14.2 Application of proof loadFor the purpose of testing, a cargo lift or mechanical ramp must be hoisted andlowered through its full range of travel with the proof load consisting ofmovable weights distributed in accordance with the designed operatingrequirements.46 Marine Order 32 (Cargo handling equipment) 2011MO32 modcomp-130604Z.docx
