Automated Inspection And Reparation Of Tram Rails
SPIE Proceedings, 1987Railway traffic causes an abrasion of the rail shapes. Regularly, it is necessary to add some bead layers in order to re-enter the dimension tolerances. At present, the welding operation is manually performed. The aim of the project is the automation of this welding operation.

Rail Inspection Meets Big Data: Methods and Trends
2015 18th International Conference on Network-Based Information Systems, 2015Rail inspection is one of the most important tasks for rail industry, in order to guarantee the safety of railway systems and control their cost. Rail are systematically inspected for defects using various non-destructive evaluation (NDE) techniques, which include ultrasonic inspection, visual detection, magnetic flux leakage method, acoustic emission ...

Thermographic Inspection of Rail-Car Thermal Insulation
Journal of Pressure Vessel Technology, 2000Over time, thermally protected and thermally insulated rail tank-cars may develop insulation deficiencies due to the continuous motion and vibrations. These deficiencies are generally not visible due to the protective outer steel jacket. A research program was undertaken to develop an inspection procedure to identify deficiencies in the thermal ...

Ultrasonic vehicle-based rail inspection
Insight - Non-Destructive Testing and Condition Monitoring, 2004Network Rail is working closely with Sperry and First Engineering in trials of a new road rail vehicle that inspects the rail using Sperry ultrasonic track inspection technology, checking for defects and future potential problems. This new machine - the UTU 5 - is said to be much faster, more efficient and more reliable than conventional manual ...

Complex for Inspection of Crane Rails Design
2019Technical condition of the crane rails has a direct impact on the performance, dependability and noiseless operation of the load-lifting crane. Therefore, to ensure the correct and safe operation of the load-lifting crane, systematic surveys of crane track are carried out. Crane rails inspection is associated with significant risks since is carried out

5th IET Conference on Railway Condition Monitoring and Non-Destructive Testing (RCM 2011), 2011
There are millions of aluminothermic welds made each year to join rail in Europe's rail network and millions are already in-service. Occasionally flaws develop during and shortly after welding that can lead to early failure and this can cause disruption to train services and costs to both the train operating companies and the maintenance operators ...

Modelling the Degrading Failure of a Rail Section Under Periodic Inspection
2004The Norwegian National Rail Administration (Jernbaneverket, JBV) has conducted a study to optimise ultrasonic testing on their lines, performed to reveal latent failures such as cracks in the rail. In this paper we propose a non-homogeneous Markov model for determining the rail failure probability under periodic inspection, considering realistic issues

Inspection of Crane Rails with Use of Monorail Mobile Platform
2018Ensuring adequate technical and operational safety of the crane requires, among others, periodic track survey. The inspection of the crane track is to detect defects in the shape of the rail head resulting from plastic deformation and the surface wear as well as cracks in the structure of the rail. An important issue is the possibility of recording and

Research on the new rail auto-inspection system
IET International Conference on Smart and Sustainable City (ICSSC 2011), 2011Presently inspecting method of crane rail had a poor measuring accuracy and lower operation efficiency. An auto-inspection system for the rail of cranes was presented in this paper, which could be helpful to improve measuring accuracy and operation efficiency. A laser scanner was used in the system to trace the position of the robot in time.
