Static testing is the first step in the elevator acceptance process. It mainly checks the structural stability and component integrity of the elevator in a static state. This test link is crucial because the structural stability of the elevator is directly related to whether it can maintain a safe and stable operating state in long-term use.

In the static test, the acceptance personnel will conduct a comprehensive inspection of key components such as the elevator shaft, car, and machine room. The verticality and horizontality of the shaft must be strictly controlled to ensure the precise installation of the elevator guide rails and prevent the elevator from shaking or offsetting during operation. The structural strength and stability of the car are equally important. The acceptance personnel will check the welding quality, material strength and connection of the car frame to ensure that the car will not be deformed or damaged when carrying heavy objects. In addition, key components such as traction machines and control cabinets in the machine room must also be carefully inspected to ensure that they are installed in the correct position, connected reliably, and meet all safety standards.

Static testing also includes inspections of elevator safety components, such as door locks, speed limiters, safety clamps, etc. These components play a vital role in the operation of the elevator. Once a failure occurs, it may cause serious safety accidents. Therefore, the acceptance personnel will test the functionality and reliability of these safety components one by one to ensure that they can respond quickly in an emergency and protect the safety of passengers and goods.

Dynamic testing is a key link in the elevator acceptance process. It simulates various working conditions of the elevator during normal operation to test its running smoothness and response speed. This test link is designed to ensure that the elevator can maintain a stable and efficient operating state under various load and speed conditions.

In the dynamic test, the acceptance personnel will start the elevator and observe its operation between different floors. They will pay attention to the smoothness of the elevator during start-up, acceleration, deceleration and stopping, as well as the flexibility and accuracy of the elevator door opening and closing. In addition, the acceptance personnel will check the elevator's response speed, that is, the elevator's start time after receiving the command and the accuracy of reaching the specified floor. These indicators directly reflect the performance and efficiency of the elevator control system.

In order to more comprehensively evaluate the dynamic performance of the elevator, the acceptance personnel will also conduct tests under special working conditions, such as full-load operation, half-load operation, emergency braking, etc. These tests are designed to simulate various situations that the elevator may encounter during actual use to test its ability to cope with complex working conditions.

Full load test and overload test are the last two checkpoints in the elevator acceptance process. They simulate the operation of the elevator under maximum load and overload respectively to verify the effectiveness of its overload protection device and safety components.

Full load test is designed to ensure that the elevator can maintain stable and safe operation when carrying the maximum design load. In this test, the acceptance personnel will place a weight equivalent to the maximum design load in the car and observe the operation of the elevator. They will pay attention to whether the elevator starts, accelerates, decelerates and stops smoothly under full load, and whether there are any abnormalities in the car and shaft structure.

Overload test is more rigorous. It is designed to verify the safety performance of the  freight elevator when it exceeds the maximum design load. In this test, the acceptance personnel will place a weight exceeding the maximum design load in the car and observe the response of the elevator. Under normal circumstances, the overload protection device of the elevator should be activated immediately after detecting the overload, causing the elevator to stop running and sound an alarm. The acceptance personnel will check the accuracy and reliability of this process to ensure that the elevator can take prompt measures to protect the safety of passengers and goods in the case of overload.

Static test, dynamic test, full load test and overload test together constitute the acceptance process of the apartment freight elevator after installation. These test links not only fully cover the key components and performance indicators of the elevator, but also strictly follow the relevant safety standards and specifications. Through this process, the acceptance personnel can comprehensively and accurately evaluate the safety performance of the elevator to ensure that it can maintain a stable and efficient operating state during actual use.

It is worth noting that the comprehensiveness and rigor of the acceptance process are not only reflected in the test link itself, but also in the recording and evaluation of the test results. The acceptance personnel will record the results and data of each test in detail and conduct a comprehensive analysis. Once any abnormality or non-compliance with the standards is found, they will immediately take measures to rectify it until the elevator meets all safety requirements.

In addition, the acceptance process also includes the review of documents such as the elevator instructions, maintenance manuals, etc. These documents are important bases for the use and maintenance of elevators, and their contents must be accurate, complete and easy to understand. The acceptance personnel will carefully check the contents of these documents to ensure that elevator users can use and maintain the elevator correctly and safely.
