Analysis on the Using Reliability of Forestry Trucks

According to statistics, the availability of forestry trucks is 85% to 90%, and the expense of maintenance takes up 30% to 40% of transportation cost. The theory of reliability used in the management of truck maintenance will be of momentous significance in improving the transportation efficiency and reducing the running cost. The analysis is based on the failure interval data of model CA142K2 trucks being used in Tahe forestry bureau. By analyzing failure rate functions the following conclusions can be acquired: tasking condition has a notable effect on the failure rate; service period can be accurately fixed by employing the failure density curve; to strengthen truck maintenance and improve management will reduce the failure rate, accordingly prolong the mileage of failure interval.
