Sensors have been increasingly used in the rail and transportation industry, thereby increasing efficiency in railway transportation. Bestech Australia present a wide range of high-precision displacement sensors, temperature sensors as well as measuring instruments and systems from Micro-Epsilon suitable for the rail industry. These sensors specialise in acceleration, vibration, angular rate and inclination measurement.
The rail tracks are always prone to high stress and load due to constant running of high speed modern trains. These loads may result in damages which could be a threat to safety and stability of trains running on those tracks. Hence, the condition of these tracks must be regularly checked to prevent any accident. In doing so, the wear of the rail head must be inspected to ensure that the rail is not too high that might lead to train derailments. ScanCONTROL laser profile scanners by Bestech Australia have the capability to measure the condition of rail heads at...
The high mileage of rail vehicles often leads to causing wear on the wheels. This affects the safety of the vehicle and generates high maintenance costs. To avoid this, test-rig setup is introduced in the track bed to measures the profile sets of complete trains. To perform the inspection of rail track wheels, high precision modern measurement system is used that includes point and line laser-based optical devices. Two optoNCDT point lasers and two scanCONTROL profile-lasers by Bestech Australia are used in this process for acquiring the wheel diameter and position and acquiring the wheel profile. In addition to these four...
Quality control of railway sleeper is performed by manufacturers using various 3D measurement systems along with optical sensors. The process includes monitoring the characteristics of embedded parts of rail sleepers such as strength, rigidity and stability. This test is done regularly to avoid any large damage. Two laser profile scanners are used in this process to scan the sleeper. Bestech Australia provides scanCONTROL laser profile sensors that travel along the portal axes and provide the profile data. In this measurement system, the data for the sleepers are linked to the relevant metal mould stored in the database in the form of sleeper...
To ensure that gantry and overhead cranes remain on the rails, several rail guided elements such as wheel flanges and guide pulleys are used. Although these elements can mesh which may lead to noise, stress in the crane construction or wear of the wheels and rails. In order to avoid high-cost maintenance to fix this problem, tracking controllers are used to ensure that the crane wheels are kept central to the rail track. Both sides of the crane drive are controlled with a number of sensors keeping the controller informed about the position and direction of the crane. Bestech Australia...
Monitoring wears in trams is very important so as to maintain good operating conditions and avoid wear of the wheels and rail. To facilitate this kind of measurement, a measurement system that can automatically detect and analyse the wear is preferred. In this case, non-contact laser profile scanners are used to record the profile of the rail. These scanners detect wears and then evaluate and analyse this data. Bestech Australia has scanCONTROL laser profile scanners by Micro-epsilon that enable measurements by creating a cross-section of the rail, hence providing an innovative and time-saving solution to scanning the rail profile. These...
Regular inspection of the railway network and its components plays a vital role in providing a safe and reliable mode of transport. Faced with the challenges of scheduled maintenance of locomotive, railway operators have developed inspection systems to monitor critical data such as a hot bearing or dragging equipment detectors. However, these systems only detect the components that have already failed, resulting in time-consuming and costly repairs. By applying predictive maintenance technologies like dynamic locomotive vibration measurements, engineers can monitor the condition of locomotives and receive early warning signs before components fail. Dynamic vibration monitoring can help increase efficiency and...
The axle load of a rail is an important design consideration in the engineering of railways. It is basically the total weight bearing on the track. It is determined by the weight of rails, the density of sleepers and fixtures, train speeds, amount of ballast, and the strength of bridges and earthworks. Generally, a given side of the track is designed to bear the maximum axle load. If the track gets overloaded by heavily loaded trains, it can be damaged. Therefore, in order to achieve higher operating speeds, the axle load on the tracks needs to be balanced. An axle load measuring system...
Inspecting railway tracks is important to ensure public safety, but it can be a time-consuming process. To address this issue, a more efficient way of inspection is needed. The goal of the inspection is to both maintain comfort and catch the early signs of wear that result from regular use. For the early recognition of faults and problems, a maintenance vehicle developed by Donfabs & Consillia can be used. The system works along with the measuring sensors offered by Micro-Epsilon. The large measuring range of these sensors helps to detect any deviation without moving from their position. In total six...
