Design and Implementation of Improved Air Brake System for 16ft Blade Motor Grader

Motor graders are used in many applications in the mining and construction field. Graders running in On-Road have to meet the RTO regulations. DGMS derives the norms and regulations applicable for equipments including motor graders operated in mines. BG825 model grader mounted with 16ft work blade is equipped with air actuated system for slow down and braking. The Study has been made to improve the confidence and reliability among the operator by increasing the no of brake actuation’s before the warning signal and also introduces the hand operated emergency brake to tackle unfavorable circumstance. The Modified air system has been implemented and tested as per the standard in the mines at customer site. The practical field test reveals that the increase in no of actuation’s and emergency brake introduction brings more operators confident and ensures safety at the higher order. Based on the feedback, the modified air brake system made as standard fitment in the present and future graders.
