I would like to answer to liftdoctor about AC systems drawbacks:
- not all AC systems heat up faster than DC systems, depend on AC system technology. AC systems equipped with DCB power modules technology have better thermal performances than old DC system with traditional power modules ( see SME inverter system in the new PRO5 Doosan serie )
- power cut back is used to save motors during overload, but AC motors can reach higher temperatures than DC motor and they can ensure higher performances during high work
- based on cycle test, new lift trucks with DCB power modules technology can ensure from 10 to 15% lower power consuption compared with old DC systems

more information in grupposme or Doosan web site
