Perancangan Pengembangan Rail Mover sebagai Alat Bantu Penggantian Rel Kereta Api

Abstract

It can be known that in the efforts to maintain and repair the railway, especially in the process of replacing the old rail into a new rail, sometimes overall still using human power or conventional means. However, there are generally tools used for the rail change process. The tool used for rail change is with rail mover. The use of rail movers is limited to the removal of rails only, while for the transfer of rails from one place to another by transporting by human power. So that in the process of working on the rails become less efficient. In addition, it only has one hook block, meaning that in one operation it can only move one rail. With such conditions, researchers will conduct a rail mover product development. The design result obtained safety factor H Beam has a value of 9,985 , deformation value of H Beam of 0.093368 mm, top buckling support value 50,465 times and bottom support 176.94 times, pin shear stress value of 7,618 N/mm2, hydraulic pressure value of 636.97 N/cm2 and scissor able to lift weight 36,440.59 N at highest position and can lift load 9,739.42 N at lowest position. The need for the number of rail movers used in the operation of the lifting and moving of the railway is as much as 1 piece of rail mover. The total cost for the manufacture of rail movers is obtained from the calculation of raw material costs and manufacturing costs. In the cost of raw materials for the manufacture of rail mover is Rp15,678,427 while for manufacturing costs of Rp13,350,000.
