What head combination is used in Sanyo elevator?

Sanyo elevators usually use a double head combination, and there are two types of elevator heads in this combination: one is a mechanical controller and the other is an inverter controller. Mechanical controller is a traditional head, which uses a mechanical drive system to control the operation of the elevator, its advantages are simple operation, easy maintenance, but its disadvantages are lower operating efficiency, consume more energy, and higher noise.

Inverter controller is a new type of head, which uses inverter circuit to control the operation of the elevator, its advantages are high operation efficiency, less energy consumption and low noise, but its disadvantages are complicated operation and high maintenance cost.

The dual head combination of Sanyo elevator is a combination of mechanical controller and inverter controller, which can give full play to the advantages of the two controllers and overcome the shortcomings of the two controllers, so that the elevator can run more efficiently, consume less energy, make less noise, be simpler to operate, and be more convenient to maintain.
