Maintenance is a fundamental task to meet the life expectancy of all equipment. One of the objectives of maintenance management is to prevent unexpected equipment downtime and to meet planned production. To do this, we must alert the presence of premature wear, performance drops, among others; through timely replacements of parts and pieces. Also, carry out corrective repairs to return the planned operability and availability. In this sense, maintenance and repair interventions must comply with the planned stoppage times to carry out the work. Characteristics of the jobs in the mining industry are the effective hours of operation above 5,000 hours per year. Therefore, increasing the hours of stoppages will cause significant economic losses. This is the case of “OVERLAND” type conveyor belts that move materials in the order of 5,000 to 10,000 TPH. Thus, the losses are considerable and can exceed amounts of US $ 1,800,000 per year due to excess hours of downtime. It is important to note that the “OVERLAND” belts transport the daily production of an open pit mine. Which, in some cases, is located 5 km from the mineral concentrator plant. In the present thesis, the design of a hydraulic release system is proposed to replace the current procedures for the elimination of residual tensile forces within the belt. Also, that allows the repair of the band in an efficient and above all safe way. With this, prevent accidents in workers and damage to the supporting structure of the conveyor belt. This design involves a remote slackening operation using a remote control system in the line of sight of the repair process. This innovative procedure will reduce repair hours compared to the traditional one. Finally, maintenance costs are calculated using both methods.
