Detailed Explanation of Elevator Electric Traction System
The electric traction system of an elevator refers to a system that is powered by an electric motor and controls the operation of the elevator through the joint action of components such as the power supply system and the speed feedback device. The electric traction system is the core of the electrical part of the elevator, responsible for providing the power required for the operation of the elevator and realizing speed control.

Detailed Explanation of Elevator Car System
The Elevator car system is the core part of the elevator, mainly used to carry and transport people and materials. It consists of multiple key components, including the car bottom, car wall, car top, car door, etc., which together constitute the elevator's carrying space.

Detailed Explanation of Elevator Control System
The Elevator control system is a core technology system used to manage and coordinate the operation of elevators. It mainly realizes the functions of elevator start, speed regulation, parking, safety protection and authority management. It is composed of hardware equipment and software logic to ensure that the elevator responds to passenger needs efficiently and safely.

Detailed Explanation of Elevator Guide System
The main function of the Elevator guide system is to ensure that the elevator car and counterweight run smoothly along the fixed slideway - the guide rail in the hoistway.

NICE3000 System E22 Fault Solution Fault Description
E22 is a "leveling signal abnormality or wire rope slippage" fault, and it is necessary to specifically troubleshoot mechanical and signal system problems.

How to self-check when an elevator fails
Observe whether the elevator control panel or information display screen displays an error code (such as E01, E02, etc.). Some elevators will directly prompt the fault type1.

The functions of ARD
The ARD in the elevator is an automatic rescue device, also known as an elevator emergency rescue device or an elevator emergency power supply. Its main function is to automatically start and provide emergency power to the elevator control system when the elevator fails (such as power outages, line failures, etc.), so that the elevator can slowly run to the leveling position and open the door to release passengers.

How to Choose Elevator Wire Rope
Elevator wire rope, a critical component of elevator systems, is essential for suspending and moving the car and counterweight. Selecting the right elevator wire rope is vital for ensuring safe elevator operation, extending its lifespan, and enhancing the riding experience. Here are the key factors to consider:

Global demand for green elevators surges
According to the Global Elevator and Escalator Market Report (2025), the global green elevator market size will exceed $32 billion in 2024, with an annual growth rate of 9.7%. Driven by the EU's "Building Renovation Wave Plan", Southeast Asia's smart city infrastructure and China's "dual carbon" goals, energy-efficient, low-carbon and environmentally friendly elevator solutions are becoming the new standard for the global construction industry.

Detailed Explanation of Elevator Traction System
The Elevator traction system is the core part of the elevator operation, mainly composed of the following key components:
