Design and manufacturing of car elevators: key technologies to ensure the stability of loads

In modern society, with the acceleration of urbanization and the improvement of people's living standards, cars have become an indispensable means of transportation in daily life. In order to meet the needs of high-rise buildings, underground parking lots, and car 4S stores for vertical transportation of cars, car elevators came into being. As a special type of elevator, car elevators must put the stability of loads first in the design and manufacturing process to ensure the safe and efficient completion of car transportation tasks.

1. Stability challenges of car elevators
Car elevators are different from ordinary passenger elevators. They have large load capacity, special size, and the transport object is a car with autonomous movement ability. This means that during the operation of the elevator, it is necessary to effectively prevent the car from sliding due to inertia or improper operation, otherwise it may cause elevator failure or even safety accidents. Therefore, ensuring the stable parking of the car in the elevator is one of the core issues in the design and manufacture of car elevators.

2. Design of car bottom fixing device
In order to solve the above problems, the bottom of the car of the car elevator is usually designed with a series of special fixing devices to firmly fix the car tires and prevent any sliding during transportation. These fixings mainly include two types: wheel holders and trenches.

Wheel holder: A wheel holder is a mechanical device that acts directly on the car tire, usually consisting of an adjustable claw or clamp. When the car enters the elevator car, the operator adjusts the position of the claw according to the model and tire size, and then locks it tightly to the tire to ensure that the car remains stationary during the elevator lifting process. The wheel holder is flexible in design and can adapt to car tires of different sizes and types. It is a key component to achieve stable transportation of cars.
Ditch: In some high-end or special-purpose car elevators, trenches are also used as a fixing method. The trench is designed at the bottom of the car to form a groove that matches the car tire. When the car enters the car and is properly aligned, the tire naturally falls into the trench. Since the design of the trench edge has a certain friction and limiting effect, it can effectively prevent the car from sliding. The trench design not only enhances stability, but also reduces the use of additional fixings, making the internal structure of the elevator more concise.

3. Technological innovation and intelligent application
With the advancement of science and technology, modern car elevators have incorporated more intelligent elements in their design. For example, by installing sensors and control systems, elevators can automatically identify car entry and start fixtures, greatly improving operational efficiency and safety. In addition, some advanced car elevators are also equipped with remote monitoring and fault diagnosis systems, which can monitor the elevator operation status in real time, and promptly detect and deal with potential safety hazards.

4. Safety standards and certification
In order to ensure the safety and reliability of car elevators, countries have formulated strict safety standards and certification processes. When designing and manufacturing car elevators, car manufacturers and elevator companies must follow these standards and pass certification tests by relevant agencies. This includes strength testing of fixtures, elevator running stability testing, and effectiveness verification of emergency braking systems, etc., to ensure that each car elevator can achieve the expected safety performance in actual applications.
