CAB FOR CONSTRUCTION MACHINERY

摘要

A cab for construction machinery (11), wherein front mounting bases (14, 15) disposed at the lower corner parts of the cab (11) are formed of base plates (14A, 15A) and fitted projections (14B, 15B), rear mounting bases (16, 17) are formed of base plates (16A, 17A) and fitted projections (16B, 17B), and cutout parts (22B, 23B) for fitting the fitted projections (14B, 15B) therein are provided in front pillars (22, 23) installed on the front mounting bases (14, 15) and cutout parts (24A, 25A) for fitting the fitted projections (16B, 17B) therein are provided in rear pillars (24, 25) installed on the rear mounting bases (16, 17), whereby a welding distance can be increased by performing a welding along a distance between the fitted projections (14B, 15B, 16B, 17B) and the cutout parts (22B, 23B, 24A, 25A) to increase a weld-mounting strength.
