ASSISTANT DEVICE FOR WELDING BOOM CONSTRUCTIONS OF EXCAVATOR

摘要

PURPOSE: the welding boom structure excavator of auxiliary device is provided to the panel for preventing the edge of substrate or omission pearl, because pearl steadily stacks side panel. ;CONSTITUTION: the welding boom structure excavator of auxiliary device includes the vertical component in two sides (110), on horizontal part (120), and welds fusing retaining groove (130). Dock the adjacent panel in side two vertically. Extend vertical part relative to bottom surface to only two panels in the bottom of the horizontal part. Welding fusing retaining groove is by the vertical component effect among pressure width and keeps pass weld fusing, so that prominent side wall panel. ;The 2012 of copyright KIPO submissions
