Railway Vertical Switch Lever

I. Product Overview

The Railway Vertical Switch Lever is a core control component independently developed by Yuerui International, specifically designed for the switching operation of railway turnout systems. As a key part connecting the turnout driving mechanism and the switch rail, it realizes the precise adjustment and positioning of the switch rail through vertical lifting and rotating operations. Integrating high-strength structural design, flexible transmission performance and anti-loosening protection, this product is widely applicable to high-speed railways, conventional railways and urban rail transit turnout systems. It features reliable operation, accurate positioning and strong environmental adaptability, effectively ensuring the smooth switching of turnouts and the safe operation of trains. As an indispensable control component in railway turnout systems, it provides stable and efficient control support for global railway operation and maintenance work.

III. Core Advantages

(1) Precise Control & Accurate Positioning

Adopting the optimized lever transmission ratio design, the product can convert the vertical operation force into precise horizontal traction force for the switch rail, ensuring the switch rail is accurately positioned without deviation. The built-in stroke positioning sensor (optional) can real-time feed back the operation position, realizing intelligent monitoring of the switching process. The rotation angle is precisely controlled through the limit mechanism, avoiding over-rotation damage to the turnout components, and ensuring the safe and reliable switching of turnouts.

(2) High-Strength Structure & Strong Durability

The lever body is made of high-strength 45CrNiMoVA alloy steel, which is formed by integral forging and precision machining, and undergoes quenching and tempering heat treatment. It has excellent tensile strength and impact resistance, can withstand long-term high-frequency operation and dynamic load impact without deformation or fracture. The base is made of forged Q355B carbon steel, which enhances the bearing capacity and stability of the whole product. The electrostatic spraying anti-corrosion coating and hard chrome plating form a double protection, effectively resisting rust, corrosion and wear from rain, snow, dust and sand in the outdoor environment.

(3) Flexible Operation & Strong Adaptability

The vertical operation design is in line with the ergonomic requirements of on-site operators, reducing the operation intensity and improving the operation efficiency. The lever surface is polished and chrome-plated, which reduces the friction during rotation and ensures flexible operation without jamming. The product supports customized production of dimensions and strokes according to the specific requirements of different turnout systems, perfectly adapting to the use needs of high-speed railways, conventional railways and urban rail transit. It can operate normally in extreme environments such as high cold, high temperature and heavy sand, with strong environmental adaptability.

(4) Comprehensive Safety Protection & Reliable Operation

Equipped with anti-loosening nuts and position locking pins, it can prevent the lever from loosening or shifting during operation, ensuring the stability of the turnout position. The edge of the lever and base is designed with rounded corners, avoiding scratches on operators and other components. The product has passed strict fatigue tests and environmental adaptability tests, with a service life of more than 15 years under normal use conditions, providing long-term reliable operation guarantee for railway turnout systems.

IV. Application Scenarios

This control component is widely used in global railway turnout systems, including:

• High-Speed Railway Turnouts: Used for the switching control of high-speed railway main line turnouts and station turnouts, ensuring the precise and stable switching of turnouts during high-speed train operation;
• Conventional Railway Turnouts: Applied to the turnout systems of conventional railway main lines, branch lines and marshalling yards, adapting to the frequent switching needs of freight and passenger trains;
• Urban Rail Transit Turnouts: Used for the switching control of subway and light rail turnouts, meeting the requirements of frequent switching and high reliability in urban rail transit operation;
• Railway Maintenance & Renovation: Used for the replacement and upgrading of old switch levers in railway turnout maintenance and system renovation projects;
