Method of manufacturing the door to be used in the construction machinery for the cab and construction machinery for cab

摘要

PROBLEM TO BE SOLVED: To reduce manufacturing costs by forming an external surface panel and an internal surface panel which differ in size, from one external surface panel and one internal surface panel through simple work.;SOLUTION: Respective frame parts 14C, 14D, and 14E of an external standard panel 14 constituting a standard door 13 are provided with fitting stage parts 15, 16, and 17 at positions to be cut in front/rear directions. Respective frame parts 18C, 18D, and 18E of an internal standard panel 18, on the other hand, are provided with fitting stage parts 19, 20, and 21 at positions to be cut in front/rear directions. Therefore, the standard door 13 can be manufactured by joining the external standard panel 14 and internal standard panel 18 together as they are. A small swivel door 33 can be manufactured by shortening the front/rear-directional sizes by cutting the external standard panel and internal standard panel at the fitting stage parts 15, 16, and 17, and 19, 20, and 21. Further, a large-sized door can be manufactured by cutting the external standard panel and internal standard panel at the fitting stage parts 15, 16, and 17, and 19, 20, and 21, and providing additional panel pieces 49.;COPYRIGHT: (C)2014,JPO&INPIT
