What are the speed standards for residential elevators?
(1) 5-story and below townhouses: Machine-room-less elevator, load capacity 800kg, speed 1.0m/s;
(2) 6-9 story townhouses: Machine-room-less elevator, load capacity 1000kg, speed 1.5m/s;
(3) 1-9 story residential buildings: Machine-room-equipped passenger elevator, load capacity 900kg, speed 1.0m/s;
(4) 10-18 story residential buildings: Machine-room-equipped passenger elevator, load capacity 900kg, speed 1.5m/s;
(5) 19-34 story residential buildings: Machine-room-equipped passenger elevator, load capacity 900kg, speed 1.75m/s;
(6) 35-45 story high-rise residential buildings: Machine-room-equipped passenger elevator, load capacity 1050kg, speed 2.5m/s; (Total lifting height H≤140M, including basement)
(7) 45-60 story high-rise residential buildings: Elevator with machine room, ordinary passenger elevator, load capacity 1050kg, speed 3.0m/s;
Elevator Selection Principles:
1. Basic Principles of Elevator Selection:
(1) Based on relevant national and local regulations and the principle of maximum economy and rationality.
(2) Based on the specific architectural and structural conditions of the project.
2. Design standards for the number of residential elevators are as follows:
(1) For residential buildings with 12 or more stories, each building should have no fewer than two elevators, one of which should be capable of accommodating a stretcher.
(2) For high-rise residential buildings with more than 60 households per unit, no fewer than two elevators should be installed. The average number of households served by each elevator should not exceed 75.
3. The above elevator selection principles are standard design criteria. If a single project has special requirements, the design can be based on the specific circumstances of the project and in conjunction with relevant national and local regulations.
Design Considerations for Barrier-Free Elevators, Fire Elevators, and Stretcher Elevators:
Barrier-Free Elevators:
(1) Residential buildings with seven or more floors should be designed for accessibility (including barrier-free elevators).
(2) The design requirements for barrier-free elevator cars are as follows:
1. The clear opening width of the elevator door should be greater than or equal to 0.8m.
2. The depth of the elevator car should be greater than or equal to 1.4m; the width should be greater than or equal to 1.1m.
3. Handrails should be installed on the front and sides of the car at a height of 0.80~0.85m.
4. Braille floor selection buttons should be installed on the sides of the car at a height of 0.90~1.10m.
5. A mirror should be installed from 0.90m to the top of the front of the car.
6. The car should have clear displays and floor announcements during its ascent, descent, and arrival. Fire Elevators:
(1) Fire elevators should be installed in tower-type high-rise residential buildings, unit-type residential buildings with 12 or more floors, and corridor-type residential buildings.
(2) The load capacity of fire elevators should not be less than 800 kg.
(3) The travel speed of fire elevators should be calculated based on a travel time from the first floor to the top floor not exceeding 60 seconds.
Stretcher Elevators:
(1) In residential buildings with 12 or more floors, each building should have no fewer than two elevators, one of which should be capable of accommodating a stretcher.
(2) According to national standards and the agreement between the group and Hitachi Elevator, the car dimensions of stretcher elevators are 1300mm x 1900mm (width x depth), the load capacity is 1050 kg, and the speed is consistent with that of residential elevators in the same building.
We know that elevators exist in every residential community; we can say that we cannot live without them, because climbing stairs is impossible to reach higher floors. my country's relevant regulations provide detailed explanations and regulations regarding elevator speed. To ensure elevator safety, they must be manufactured according to relevant standards.
