1. Quantity selection

The choice of the number of Passenger Elevators mainly depends on the estimation of the passenger flow. The accurate analysis of the passenger flow of different buildings requires a large amount of statistical data, which is currently not available. Different designers often make estimates based on their own experience. The following are some experience values ??for reference only.

(1) Residential: 70 tower dwellings/unit; panel dwelling 100 units/unit; 3 elevators should be installed on more than 20 floors.

(2) Hotel: The number of passenger elevators is based on 100 rooms/set, and the number of service elevators is considered as 1/3 of the passenger elevators.

(3) Office building: according to the construction area of ??5000m2/set or according to the number of office workers 250 people/set.

2. Speed choice

Increasing the speed of the elevator can shorten the average travel time and improve the service level of the elevator, which depends on the service level required by the building and the height of the building itself. The increase in speed may greatly increase the cost of elevators.

For office buildings, low-speed elevators below 2m/s should be considered for buildings below 75m. For buildings between 75m and 150m, the elevator speed may increase by 0.5m/s for every 20m increase in height. For residential buildings, generally only 1m/s elevators are considered for multi-storey houses, 1.5m/s for towers or slabs with 10 to 16 floors, and 2m/s for elevators with 16 to 22 floors.

3. Choice of deadweight

Overloading is forbidden by the elevator, and the load capacity of the elevator is the maximum weight transported by the elevator at a time. The choice of this parameter directly restricts the maximum service capacity of the elevator. For high-rise residences and apartments, it should be more than 1000kg; for office buildings, it should be more than 1350kg; for large shopping malls, it should be more than 1600kg.

4. Selection parameters

Elevator design should clarify the following parameters: elevator civil engineering requirements, such as layout, machine room location, hall door size, car decoration, etc.; elevator usage description, including landing, travel, service floor, etc.; number of elevators; elevator rated parameters , Such as rated speed, load, operating system, control system, leveling accuracy; elevator power requirements, lighting requirements, communication requirements, etc.

When the Sightseeing Elevators are arranged side by side, there should not be more than 4 elevators. This is because the stopping time of the elevators generally does not exceed 8s, and passengers may not have time to enter the elevators. If the elevator is installed in zones, it can be divided into one area on the 15th floor, and 600 × 1800 fire doors are installed every 11m from the hoistway of the non-stop floor. If the depth of the elevator pit exceeds 2.5m, an iron climbing ladder shall be installed, and an overhaul socket and well safety lighting (36V) shall be installed at the bottom of the pit. For fire-fighting elevators, the power supply requires dual-circuit power supply, and is equipped with a control system for forced landing on the first floor in a fire-fighting state. In high-end buildings, sometimes it is necessary to make some special decorations for the elevator car and hall station, and the reserved size should be considered when designing
