PURPOSE:To reduce the number of assembling processes, to decrease the weight of parts, and to improve the strength of a base part, by a method wherein a main frame, whereon a car body is placed, is located in condition to extend from the front end of a machine body to the rear end thereof. CONSTITUTION:A front top and front lower links 11, 11 are mounted to the front part of a machine body to form a front working machine mounting device. A rear top link 12 and rear lower links 13, 13 are also projected at the rear to form a rear working machine mounting device. A longitudinal frame consists of a right main frame 27 and a left main frame 28. The right main frame 27 has its rear part bent at right angles and brought into contact with the left main frame 28 and welded thereat. The right and left main frames 27 and 28 are both formed with a pipe, and the front ends thereof are brought into contact with front top link brackets 38L and 38R from the side and are securely attached. |
