ABS (Anti-Lock Brake System)

ABS (Anti-Lock Brake System) is an electronic system which continuously monitors the trailer's braking system to prevent tire/wheel lock-up during the application of the trailer air brakes. Whenever the system senses a sudden loss of tire/wheel rotation it over-rides control of the air brake application to rapidly apply and release the brakes to maintain control and prevent tire/wheel lock-up. ABS is required on all of the trailers Rogers manufactures up to 120,000 lb. gross vehicle weight. However, ABS is standard equipment on all Rogers trailers for which it can be installed, whether or not required by law. Anti-Lock Brake Systems are available in a range of configurations based on the quantity of wheel sensors and/or modulator valve assemblies. The law requires a minimum 2S/1M system (2 sensors / 1 modulator) for trailers. A system of this configuration monitors the tire/wheel rotation of only one axle and, when necessary, controls the braking of all wheels equally. Rogers equips all of our trailers with ABS systems of 4S/2M configuration - 4 sensors / 2 modulators. Since the axle loads can differ from axle to axle, we believe that having sensors on two axles provides safer and more reliable operation of the trailer's braking system. Also, the presence of 2 modulators valve assemblies provides independent brake control from roadside to curbside of the trailer during the application of the ABS resulting in better vehicle control and safer operation. In addition to the enhanced safety of the trailer's air brake systems, ABS also greatly improves tire wear whenever the trailer is operated empty or with a lighter than capacity load.
