| Zusammenfassung: | The utility model relates to an escalator truss does not have welding encapsulating structure, there is not the welding encapsulating structure including setting up the steel sheet mounting between staircase bottom plate and staircase are lapped the lower extreme and the top of steel sheet mounting do not are equipped with staircase floor support spare and staircase apron support piece, staircase floor support spare and staircase apron support piece pass through the briquetting roof pressure respectively on the steel sheet mounting, the briquetting passes through the bolt and is connected with the steel sheet mounting. Escalator truss does not have welding encapsulating structure is owing to the change of not adopting welded connection not produce matter to the former truss raw and other materials of staircase to to the change that the former truss raw and other materials pulling force of staircase did not produce matter, this nothing welding encapsulating structure still can be strengthened escalator truss's |
