RANCANG BANGUN SAFETY DEVICE COOLING DOWN AUTOMATIC PADA UNIT HEAVY EQUIPMENT DOZER D3K CATERPILLAR BERBASIS MICROCONTROLLER

Abstract

The occurrence of problems regarding operating procedures that are not suitable for heavy equipment in the field is one of the causes of component life which is not maximally achieved. Therefore it is necessary to have an innovation to make it easier to monitor and operate heavy equipment, especially when there is a shift in work shift for heavy equipment operators. Operator experience in several mining activities, many operators shut down the engine suddenly so that the impact on the engine can cause over heating which results in excessive wear and will have an impact on engine performance. And therefore the purpose of design a microcontroller-based cooling down safety device is a tool that functions to turn off the engine when the engine is low idle with time settings according to the standard operating procedure of each machine. For machines that have been operated under load, the engine must be low idle / cooling down for a while, so that the heat on the engine surface is cool enough, so that hot components can be properly lubricated. By design a cooling down engine safety device, it is hoped that it can assist in the monitoring and operation of heavy equipment. From the results of field testing, the relay that controls the unit's electricity functions properly and the cooling down safety device has a precise timing.
