The elevator purchased by the owner is provided with a one-stop service, including design, installation, and after-sales maintenance, all by a single elevator company. All information is in the hands of the elevator company, and the safety and reliability of the elevator are solely determined by the installation company. The safety of commercial elevators in the country is subject to professional department inspections and acceptance before they can be put into use, and regular maintenance is required. However, there is no such strict regulation for residential elevators, especially since documents classify elevators under 320KG as "non-harmful to the public equipment," making safety inspections even less likely.
Consider the emergency contact number for elevators and the self-rescue procedures. The emergency contact number requires making an external call for assistance using a landline phone, which can be from the property monitoring room, etc.; while the self-rescue procedure allows the elevator to initiate self-rescue in case of program errors, ensuring the elevator remains safely stable until it reaches the nearest floor.
Due to limited space in some villa elevator shafts, the actual cabin space is generally between 0.8 to 1.6 square meters. According to anthropometric studies and wheelchair dimensions (width of 68 cm), the width should not be less than 0.7 meters, and the depth should not be less than 1 meter.
Residential home elevators typically do not exceed five floors, with the third and fourth floors being the most common. They are predominantly used by the elderly, children, and individuals with mobility issues, thus the speed should not be too fast, generally kept between 0.3-0.4 meters per second. This elevator model is designed with a speed of 0.4 meters per second.
Early on, elevators were mechanical, with loud noises. However, modern elevators are much quieter. But residential elevators are installed close to living spaces like the living room, so noise consideration is a must for a more humanized experience. Ensuring the motor noise does not disrupt normal daily life is crucial for the normal use of the elevator.
Energy consumption is also a critical aspect; elevators must be energy-efficient, as it's not practical to purchase one that is rarely used just to save on electricity costs. Residential elevators have a smaller load capacity, so a standard 220V power supply is sufficient.
Many elevator companies lower their sales prices to attract customers, which can lead to inadequate or non-existent free maintenance services in the future, potentially resulting in exorbitant long-term maintenance costs. Regular maintenance checks are crucial, however, which is why reputable elevator companies may charge higher prices initially, but in the long run, it's a worthwhile investment.
1. Installation of shaft elevators requires vertical alignment for the elevator's placement. Whether it's a structural shaft or a reserved elevator door spot, the installation must be vertically aligned. Therefore, prior to installation, the verticality of the structural walls and the completed car frame must be inspected.
3. The elevator car's own height must correspond to the reserved dimensions of the civil construction. Here, three dimensions are primarily considered: the pit depth, the top floor height, and the host installation height. The pit must be at least 35 centimeters deep; if there's no pit, the car must be elevated, allowing for two steps. The top floor height refers to the car's height at the top floor, maintaining a small safety margin from the host. The car is generally about 2.2 meters tall, and the top floor size should be higher than 2.6 meters. The host installation size ensures a small installation dimension for the host, typically 0.4 meters is sufficient.
5. Elevator track frames are fixed to the well wall, thus the well wall must be reinforced with concrete pouring or concrete ring beams to ensure the stability of the track frame installation. The depth of the expansion bolts used for installing the track frame must exceed the radius of the concrete beam by two centimeters to ensure a secure fit.
7. The elevator shaft is exclusively for elevator installation; no other equipment, pipes, or cables are permitted to be installed or laid within the shaft.
