TABLES / EXPLANATIONS AWG-SIZESAdditional testsAdequate testing of the good operating characteristicsneeded for flexible electric cables for cranes andmaterial handling equipment is not possible withthe tests specified by DIN VDE. Prysmian flexibleelectric cables for cranes and material handlingequipment are therefore subjected to additional andcontinuously mechanical tests at the manufacturer‘sworks (Kabel- und Leitungswerk at Neustadt nearCoburg). These additional tests facilitate timecompressedexamination of the running and servicecharacteristics under different kinds of mechanicalstress, such as reversed bending strength, runningover sheaves, flexing work and reeling operation inrelation to tensile load and bending radii.The additional tests can be seen in table 4/16.Schematic representation of the additional testsReversed bending testBased on DIN VDE 0281, Part 2Testing of flexible electric cables for cranes and materialhandling equipment under increased loads.Cable diameter up to 50 mm, maximum tensile load 3000N. Each movement from one extreme position to another(180°) is counted as a cycle.Roller bending test type ATesting the roller bending characteristics of flexibleelectric cables for cranes and material handling equipmentbased on DIN VDE 0282, Part 2. Cable diameter up to50 mm. Each movement between the extreme posit ons scounted as a cycle.Roller bending test type B (Tender test)Practice-oriented testing of flexible electric cables forcranes and material handling equipment with reference torunning and service characteristics.Cable diameter from 20 up to 60 mm. Each movementbetween the extreme positions is counted as a cycle. Roller bending test type C (Flexing test)Testing the running characteristics (flexing) of flexibleelectric cables for cranes and material handling equipmentfor evaluation of the mechanical service characteristics.Cable diameter from 60 up to 120 mm. Each movementbetween the extreme positions is counted as a cycle.Moving distance 2 m.Reeling testPractice-oriented testing of flexible electric cables forcranes and material handling equipment with reference torunning and service characteristics.Cable diameter up to 25 mm.Each reeling or unreeling operation is counted as a cycle.The reeled length is 8 m.Torsional stress testThe cable is alternately twisted left and right through anangle a by application of the tensile force F.Torsional angle ± 360 °Torsional torque 200 NmTensile force 4000 NTable 4/16
