SPM Rail Profile Measuring Instrument
Detail Information
Overview
The SPM portable rail profile gauge is a rail cross-section profile measurement and analysis device developed by China Railway Materials Operation and Maintenance Technology Co., Ltd. It can accurately measure rail profiles and calculate key parameters such as rail side wear, vertical wear, superelevation, track gauge, equivalent conicity, and wheel-rail contact characteristics. When used with its dedicated tablet PC and proprietary software, it enables real-time profile analysis and data management.
Basic Parameters
Key Featuers
Profile Measurement
Used for measuring rail profiles on tracks, as well as switch points, stock rails, and crossing noses in turnout areas.
Profile Analysis
Capable of calculating vertical and lateral rail wear, and analyzing wheel-rail equivalent conicity and contact compatibility.
Profile Deviation Correction
The software automatically corrects profile deviations caused by installation and positioning errors.
Automatic Data Upload
Measurement data can be automatically uploaded in batches to the WRPS database, facilitating centralized profile storage and management.

Frequently Asked Questions
What is this product used for?
The SPM portable rail profile instrument records the rail cross-section profile on site and compares it with the design template, showing wear and deviation from the target profile.
Which wear parts and consumables does it use?
Profile measuring templates and replacement measuring heads.
Does the SPM compare against a target profile?
Yes. It records the actual rail cross-section, overlays it on the design template, then calculates vertical wear, side wear and equivalent conicity.
How are measurement records kept for audit?
Each reading is stored with date, location and rail section, and exports to PDF or Excel so acceptance records can be filed per job.
