The main control system adopts Hitachi's unique dual microcomputer control technology, which is more efficient, safe and reliable; Adopting Hitachi's latest vector control frequency conversion technology, the speed and output torque can be accurately controlled, and the ride is stable and comfortable. The main components of the control cabinet system are imported parts. The safety control system adopts Hitachi nuclear safety control technology, and the safety components adopt double safety protection design. With Hitachi's unique and perfect fault self-diagnosis system, Hitachi elevator has become the safest and most reliable elevator at present.
Advantages of Hitachi elevator
1. Material: Hitachi is unique among all stainless steel detachable steps and pedals imported from Japan, and its strength and service life are three times that of aluminum alloy steps from other elevator manufacturers.
2. Main engine and transmission system: Hitachi high-precision parallel-axis helical gear reducer and optimized transmission system design are adopted, with high running efficiency, stability, low noise, transmission efficiency increased by 15% and energy consumption reduced by 30%.
3. Handrail belt drive system: Hitachi's unique linear drive is adopted. Compared with curve transmission, it has the advantages of less bending points, less running resistance, high transmission efficiency and less heat generation after long-term operation.
4. Patented design: patented 8mm safety steps, effectively protecting passenger safety; Patented pedal anti-slip treatment; Yellow frame design of detachable polymer material: arc stainless steel inner cover plate can effectively prevent passengers from stepping on it.
