Testing Equipment & Benches
HVAC Compressor Test Cabin
The HVAC Compressor Test Cabin is used to test the air-conditioner compressor of rolling stocks assets. The system is constituted of a control panel, a tilting traction cart with a support for cooling gas compressor, a tank and a soundproof cabin. The control panel includes the HVAC’s software of its manufacturer (provided by you) therefore allowing the HVAC Compressor Test Cabin to create cycles as if they were happening inside the car. All test results are recorded by the system and the report indicates if the air-conditioner is faulty or not.
High-Speed Circuit Breaker Test
The High-Speed Circuit Breaker Test is a portable power supply intended to adjust high-speed circuit breaker. This circuit breaker testing can be made for all types of rolling stock assets. It is constituted of a transformer, a voltage arrangement and output current by AC/AC converter with inverse polarity thyristor, a cooled silicon bridge rectifier, output voltage adjustment buttons, a converter starter with voltage potentiometer and a control panel.
Brake Test Equipment
The Brake Test Equipment regroups several different types of brake test equipment: brake cylinder test bench, brake cylinder with independent compressor test bench, distributor test bench, electro-valve and pressure gauge test bench, tension brake test bench and the mobile brake test equipment. Each test bench can test an equipment of the brake system of any rolling stock asset. They can be made for one type of material or they can be made a combined material test benches. It all depends on what you need and your technical specifications. Each of these benches can be used in automatic testing mode allowing an operator to supervise several operations at a same moment.
Pantograph Test Bench
The Pantograph Test Bench is used for the removal, installation and adjustment of pantographs. The repair of pantographs on the workbench takes place in the same way as if the repair was made on the roof of cars. Since the loading detection assembly is motorized, it allows all the measurements and calibration of the operation area of pantograph to be made properly. Mechanical protection are also present on the bench in order to avoid damages to the pantograph.
Reduction Gear Test Bench
The Reduction Gear Test Bench is constituted of a steel construction, where a motor drive is used to connect the cardan joint and gears and where another motor is used to connect brake to cardan shaft and axle. The structure of the test bench is suitable both for test and repair of the reduction gear. The design of the test bench is made according to your rolling stock assets, and if you have similar different brands, it is possible to test them on the same bench by changing adapter plates for each brand.
Compressor Test Bench
The Compressor Test Bench is used to test the compressor of rolling stocks assets. The system is composed of one control panel, a tilting and supporting instrument, an air tank and a soundproof cabinet. All test results are recorded by the system and the report indicates if the compressor is faulty or not. During the test procedure, instantaneous current absorption takes place, there is an activation of lock when pressure obtained and potential calibration of on/off cycle and there is an air current in terms of liter/minute generated by the compressor being tested.
Traction Motor & Compressor
Lifting & Rotating Test Bench
Lifting & Rotating Test Bench
The Traction Motor & Compressor Lifting & Rotating Test Bench is used for maintenance works on traction motors and compressor motor block. The configuration of the Traction Motor & Compressor Lifting & Rotating Test Bench is made for lifting and rotating traction motors and compressor motor block with different design and dimensions.
Motor’s Rotor Balance Test Bench
The Motor’s Rotor Balance Test Bench is used for confirming the appropriateness of the balance of electric engine rotors. Thanks to its design, Motor’s Rotor Balance Test Bench simplifies the calibration procedures and enable much more accurate measurements. The measurement cycle is fully automatic and gives detailed report of the unbalance values.
Automatic Coupler Test Bench
The Automatic Coupler Test Bench is designed for the test of automatic couplers of electric rolling stock assets. The system works with a stationary coupler (the one being test) and a mobile coupler. Both couplers are connected to pneumatic cylinder via a rod, and are loaded with extra weights to improve the balance of the equipment. The system simulates the coupling and decoupling procedures of two couplers, and is able to give a detailed report in case of failure of the coupler.
Spring Test Bench
The Spring Test Bench provides a load to test the springs of any rolling stock asset. The bench uses a height measuring system, a hydraulic press cylinder and a loading measurement instrument in order to realizes the test procedure. The height measurement system is capable of yielding a real-time graphic description of the tested spring (force/crushing). The load measurement system on the base frame is composed of load cells capable of measuring the load during the test. The system has its own spring database with procedures for each type of spring, and records each test and its report.
Damper Test Bench
The Damper Test Bench is used to recreate the operational cycle of a damper on a rolling stock asset and evaluate the damper’s efficiency. A movable traverse for attaching dampers provided with load cells an a hydraulic system are used in order to realize the cycle procedure. The system has its own damper database with procedures for each type of damper, and records each test and its report.
Secondary Air Bag Test Bench
The Secondary Air Bag Test Bench is used to verify the runtime of air bag systems which are placed on railway cars making both real illustration and simulation of the load on air bags. Both the dynamic displacement and static displacement are carried out by the bench. The continuous displacement is continuously changed by changing the angle. The test procedure shows the geometry of load transfer between the center of bogie hub and the center of air in a state similar to its original.
Train Battery Charge Bench
The Train Battery Charge Bench is used to charge batteries of electric rolling stock assets. The system is composed of a bench with charging connectors equipped with aspiration system for the hydrogen smoke emitted during the charging of batteries and a control unit controlling the charging cycle. The liquid waste generated from the charging of battery is collected in a container that can be easily moved toward beneath the loading surface.
Hollow Axle Ultrasonic Test Bench
The Hollow Axle Ultrasonic Test Bench is a mobile test bench used to make ultrasonic inspection of axles still mounted on a rolling stock asset. The system includes a holder head containing ultrasonic probes, a motor and a gear unit for rotation of probe head in axial direction, and a slip-ring system to which ultrasonic signals are transmitted. This mechanism is disassemble for new mechanisms designed for assembling supply unit to other types of axles.
