ANALISIS RASIO KATROL TERHADAP MESIN BOR AIR BAWAH TANAH

A water drilling machine is a tool that makes it easier for humans to make dug wells, in the manufacturing process it requires a tool to lift and lower pipes which are relatively large and heavy, so a tool is needed, namely a pulley. Which is following its use to ease in pulling and lowering the machine and the drill pipe. How to analyze the pulley-to-lift ratio of an underground water drilling machine.
