JUNCTURE STRUCTURE BETWEEN INDUSTRIAL VEHICLE FRAME AND COUNTERWEIGHT

摘要

PROBLEM TO BE SOLVED: To improve external appearance quality by eliminating a problem that a difference due to a manufacturing method of welding and casting becomes a difference in width measurements of a vehicle when assembling to be appeared as a displacement of a butting surface as shown in Fig. 4. SOLUTION: A butting portions 4 between a frame 2 and a counterweight 1 is obliquely disposed so as to have same length. An end portion of a side surface plate 3 of the butting portion 4 of the frame 2 is bent inward at the bending measurements of a same degree as as-cast roundness RC of the counterweight 1 to be the butting portion 4 between the frame 2 and the counterweight 1.
