AbstractProcess coal mining use hitachi excavator 2500 type of backhoe to lift of coal and top soil. Maximum capacities of bucket according to manufacturer standard is 27 ton, but actually bucket of overload condition with payload capacities go up 37,95 ton. This research analyse strength component of arm at condition of overload activity. Material of Arm is material of structural SS400 steel with permission tension boundary (yielding point) equal to 205-245 N/mm2 and at second part of bracket tied on material HT 590 with permission tension boundary (yielding point) 500-515 N/mm2. The result showed that the components arm at condition overload activity has force and tension increase 23-27 % from condition of normal activity. Maximum tension at front hydraulic cylinder pivot 62,704 N/mm2, while maximum tension at bracket happened in bracket slider bushing at condition overload activity 428 N/mm2. Value both of the tension smaller than material permission tension so that materials at component of arm in compliance with applicable standards and met the eligibility safe condition. Keywords : Bucket excavator, condition of overload activity, analyse strength, safe condition.
