China Digital Track Gauge (with Switch Rail Lowering Value) - China Supplier
Digital Track Gauge (with Switch Rail Lowering Value)
Negotiable
Category: Electrical Equipment & Supplies/Low Voltage Electrical/Low Voltage Fuses
Company: Xiangyang Lianjie Electromechanical Co., Ltd
Product Description: The Digital Track Gauge (with Switch Rail Reduction Value) is an essential tool for railway track inspection.Its primary function is to accurately measure the track gauge. The track gauge refers to the distance between the two rails of a railway track. This tool digitally displays the measurement results with precision, eliminating potential human errors associated with reading traditional measuring instruments, making data reading more convenient and accurate.In terms of measuring the switch rail reduction value, it effectively measures the reduction value of the switch rail relative to the stock rail. This is crucial for ensuring the smoothness and safety of trains when passing through special track structures such as turnouts. A proper switch rail reduction value ensures smooth wheel transition and prevents derailments and other accidents.This type of track gauge is typically made of sturdy and durable materials, offering excellent wear resistance, and can adapt to the complex and harsh working conditions of railway sites. Moreover, its digital display device is generally stable and can operate reliably under various temperature and humidity conditions, ensuring the accuracy and reliability of measurements. more>
