We perform maintenance on all electrical equipment, including motors and pumps.
Maintenance is an essential task to keep equipment in optimal condition and to prevent equipment troubles. At Nakao Electric Industry, we conduct maintenance on all electrical machinery, starting with equipment inspections. Unusual noises from motors, resembling screams (like mixing a lot of pachinko balls), are signs that indicate serious issues. Please conduct a diagnosis and inspection immediately. If left unattended, it may lead to smoke coming from the motor and cause it to stop. Additionally, we perform legally mandated regular inspections for hoists, cranes, motor chain blocks, lifts, dumbwaiters, elevators, escalators, mobile devices (self-propelled ramps), and stage equipment. For more details, please contact us or refer to our catalog.
