Mermec Group has won a contract from Morocco’s national railway operator Office National des Chemin de Fer (ONCF) to deliver 15 hot box and hot wheel detectors (HBD/HWD) along with three maintenance control positions and one central control unit.
The systems are contactless, stationary thermometers that are installed along the rail track in a hollow steel sleeper and are designed to measure the temperatures of different types of axle boxes and wheel sets.
Under the deal, Mermec will install the HBD/HWDs on five single-way and five double-way locations of the rail network to detect the axle, wheel and brake temperatures of each train passing through them.
According to the company, the detectors are designed to prevent highly dangerous possible causes of accidents or of expensive wear that result in severe damage, such as overheated axle bearings or critical brake conditions.
Capable of measuring the complete temperature of the inspected parts, the systems will send alerts to the train driver and the local control office to flag up a potentially dangerous situation.
Complete data is collected by the detector’s central control units, providing in-depth analysis of data for trend analysis over time.
The accuracy of the systems’ measurement is assured by an auto calibration device, while a TCP/IP network integration helps to continuously check the systems’ status.
Mermec expects to deliver the first HBD/HWD system in the first quarter of 2013, and the project is scheduled to be completed by the end of the year.
