Train formation, especially for underground mining, has cardan joint for tension and compression resistant interconnecting of adjoining load beams, and support carriages on rail are located in region of cardan joints

摘要

Train formation has several load beams (3-8) coupled together with each two adjoining load beams interconnected tension and compression resistant via cardan joint (9). Support carriages (10) which are movable along suspended travelling rail (1) are located in region of cardan joints. Each cardan joint is constructed from spherical component retained by two-member fork and multi-section housing enclosed and form-fitting around spherical component in vertical plane.
