Based on the assessment of the building structure and the safety and convenience of personnel access, planning is carried out for different needs, layouts, and circulation routes.
When installing a lift shaft from the exterior of the building, attention must be paid to structural integrity and safety


Elevators move up and down frequently, and the cables that provide power for their operation inevitably move along with them. Due to frequent starts and stops, coupled with drastic load changes, to ensure the elevator's acceleration and deceleration performance, as well as precise landing stops, it is necessary to keep the voltage drop of the power supply within a certain range.
Therefore, sufficient power supply equipment capacity is an important factor in ensuring elevator performance. In addition to the power supply for the elevator, there are also power supplies for lighting, ventilation equipment, maintenance, and intercom cables.
