The safest and most accurate way to test a braking system is to use a Roller Brake Testing system.
These have proven to be the most accurate and repeatable test platforms. Individual axles are tested one at a time, easily detecting axle imbalance or low brake efficiency.
Rollers are spun via electric motors or hydraulic power, a load cell measures the amount of pressure against it as the brakes are applied and attempt to slow the roller speed.
The best systems measure the weight of the axle and provide all the necessary calculations for you. More load cells equals’ greater accuracy.
MAHA has been making roller brake testers since 1969.
Roller size, roller surface, roller speed, drive motor size, load cells and gearbox are all combined to produce accurate, repeatable test results over many years of operation.
This system is one of the most extensive test and diagnostic roller brake testers available in the world today.
Options are available to make sure you have a system which delivers exactly what’s needed for your specific requirements.
LOAD SIMULATION FOR ROLLER BRAKE TEST SYSTEMS by MAHA
When testing heavy vehicles with high load/empty ratios, (e.g. heavy goods vehicles, semi-trailers and trailers) a simulation of a load is required in cases where loading vehicles for the braking performance test is not always possible (e.g. in the case of foodstuff transporters and containers or dangerous goods vehicles).
MAHA has two simple load simulation solutions which can be retrofitted easily and at a one off investment coast.
Firstly the holding-down device with two hydraulic cylinders anchored firmly to the floor. In this type of load simulation every axle must be held down separately.
Furthermore, MAHA offers a holding-down device with hydraulic cylinders that can be moved on tracks. It is, for example, advantageous in the case of twin axles, as the fitting time is reduced.
Secondly MAHA offers load simulation via lifting roller sets especially for twin axles.
During the braking performance test the roller set is lifted, thus increasing the axle load by unloading the other axles and placing the entire weight of the structure on the axle to be tested.
According to the experience of international testing organisations this solution can achieve the required axle load in 90 percent of cases without further fixing of the vehicle.
These solutions provide workshops and testing organisations with the greatest possible flexibility for load simulation while simultaneously requiring very little time to complete the test.
