FAW Delivers OGRA Compliant J5P-360 Trucks to PSO
April 25, 2018

Once at an Expo event one of the vendors showed me an ABS unit, which he was calling “EBS”. He said that contrary to the definition of ABS in a passenger car where ABS means 4-wheel, 4-sensor, 4-valve, 4-channel system which can individually monitor each wheel and individually control each, ABS for 10-wheelers is single channel, which can monitor all wheels but has a single valve which means if 1 wheel is locking up, the valve will reduce pressure to the entire system, whereas the EBS is a more advanced mutichannel system which can control a valve at each wheel. In case of a 22-wheeler, there are 12 brakes (6 axles), and the EBS is sophisticated enough to monitor each of the 12 wheels and intervene only for the one which is locking up. This greatly increases the stability, steerability, stopping distance and safety of the truck. He also told me that this device is available as an additional add-on for the older trucks which came without ABS from the factory, since it is OGRA’s requirement for oil tankers to have all-wheel independent ABS.

A few years later I went to OGRA website and found this “Road Transport Vehicles, Containers and Equipment for Transportation of Petroleum” https://ogra.org.pk/download/208 on this page https://ogra.org.pk/standards. This document dating 2009 has a dedicated heading #17 for Brake Systems, however I cannot see any directive related to the requirement related to ABS above. Only that vehicle must meet the wheel lockup criteria of EEC 71/320 which is exempt if the vehicle has ABS.
Nothing as such which makes the presence of ABS or EBS compulsory.

What is the answer to the above question?

In other info, the OGRA requirements allow a braking distance of 15.5 metres at 30-35 kph speed on a dry road. Hoping the best that they update the requirements for 2023 for the truck companies to fit disc brakes which can reduce stopping distances, provide better wet road performance and improved brake fade behaviour (Kallar Kahar anyone?)
