The conventional method of building a  wire rope ladder for Haul Master involves a hot shaping process, in which the retaining bush is heated with oxy-acetylene flame and then hammered. This method has several  drawbacks: it requires a long time for the  hot bush to cool down, workers have to spend more energy to do the work, the work must be done by at least 2 persons, the use of oxy-acetylene gas  may lead to a fire hazard, and it generates harmful gases for workers. This study aims to devise a press tool for use in building wire rope ladders for Master Haul that can make the fastening of the retaining bushes to the wire ropes faster and safer without the need of oxy-acetylene. The collection of data in this study was done through field observations and interviews with workers. The results of data analysis were then followed by planning, designing and building the press tool, testing  the tool, and analyzing the test results. The outcome of this study is a bush pressing tool with dimensions of 600 mm x 1050 mm x 1050 mm with  a press capacity of up to 50 tons. The conventional process using 2 kg hammers required a hammering time of 4.6 minutes, while using this press tool only took 1,5 minutes.
