Abstract

Quayside Container Crane (QCC) is one of the heavy equipment used by the Nusantara Port Handal company. The Telescopic Spreader is one of the equipment found on the Quayside Container Crane (QCC). The mechanical power for the QCC work process comes from an induction motor or asynchronous motor. In operation, lifting power often weakens, causing business processes to idle. QCC mechanical resources come from induction motors or asynchronous motors, of course the work process depends on the reliability of the motor. Based on monitoring and recording, the induction motor used by QCC with a capacity of 7.5 kW often experiences a weakening of rotational power during busy work activities. After measuring the temperature when the induction motor was loaded, the temperature reached 440C and after measuring the motor stator resistance value, it was 1200MΩ. Based on the analysis, the increase in motor temperature caused a decrease in lifting power due to a decrease in the Insulator Resistance value which caused voltage leakage between the armature windings. Motor resistance decreases due to the reduced ability of the stator insulator due to increased heat, with a decrease in lifting capacity based on measurement results causing the vibration value to increase from the threshold, thereby disrupting the construction of the stator armature. To overcome this, re-varnishing of the insulator has been carried out which results in an increase in the resistance value of the stator insulator.
