AGN 048 – Rubber Tyred Gantry (RTG) Cranes The RTG Crane application is a quite unique situation. For reasons of making the alternator output characteristics suitable to power the Crane’s drive motor, combined with the duty cycle of the variable crane motor load, the alternator is usually operating with quite low levels of winding temperatures. Rubber Tyred Gantry (RTG) Crane – Delta Electronics Low Power Efficiency (Power Factor or PF): The RTG crane work load constantly changes which may cause low PF, and the user may be fined by the local electric company. Delta’s Solution: Delta Industrial Automation has introduced Delta’s AFE2000 Series active front end to RTG crane systems, which has helped to improve the PF while collecting regenerative power.
