Abstract
Safety of the operators in any equipment can be achieved by both passive and active systems. Passive safety system includes Seat belt, air bag, bumper, and other structural components which protects the operator from injuries during accidents. On the other hand, Active safety systems like Braking, Steering, Collision avoidance system, operator fatigue monitoring systems, etc., minimize and eliminate the accidents among which the Brake system is primarily used to control and stop the equipment. Considering the field operating conditions of motor grader, it is very essential to provide fool proof braking system to control and stop the equipment. In order to obtain maximum productivity the equipment speed is kept substantially high. Brake systems are operated using Air, Hydraulics, etc., among which the Air brake system offers simple and easy serviceability over hydraulic system. Integrated air operated service brakes and hydro pneumatic parking brake system designed and developed for 12 feet working blade class motor grader with BSIV emission electronic engine. Two independent criss-cross service brake lines designed to be fail-safe. As one service brake line fails, even equipment can be controlled and stopped by another service brake line. An internally expandable shoe brakes at all four driving wheels of the tandem axle provides effective braking without any brake lag. Low pressure warning signals in two independent service brake lines provided. Fool-proof sliding disc spring applied hydraulic release type parking brake at transmission output shaft actuated by Patented hydro pneumatic system prevents faulty usage by the operator. Electronic interlock provided to avoid gear shifting when parking brake is applied. Service and parking brakes are tested as per ISO 3450 standard and found satisfactory.
