A EXCAVATOR FOR PREFABRICATED HANDRAIL STRUCTURE

摘要

PURPOSE: A prefabricated handrail for installing an excavator is provided to prevent damage due to the interference of the handrail during work by applying a rail support unit capable of assembling or disassembling the handrail. CONSTITUTION: Both ends of a prefabricated handrail(20) for installing an excavator are inserted into a rail support unit(30) fixed to the upper part of a fuel tank(4) and an upper frame(2). A bolt connection groove is formed on the rail support unit for fastening an anchoring bolt. A bolt penetration hole(21) is formed on both ends of the handrail corresponding to the bolt connection groove. A plurality of the bolt penetration holes and the bolt connection grooves are formed in order to control a connection height.
