DEVICE TO COUPLE TWO GUIDE SECTIONS Russian patent published in 2015 - IPC B23K37/04 B66C7/02 B23K31/02 E01B25/24 

FIELD: machine building.

SUBSTANCE: invention relates to devices for butt-to-butt connection of sections of a guide for suspended movable hoisting mechanisms and similar devices consisting of two halves. The sections are coupled with the help of bushes welded to their ends. At coupling the sections, their bushes are matched and a bolt is passed through them with a nut being screwed onto its protruding end. The end section of a weld joint, which connects the bush with the guide section wall, extends sidewards from the bush by the distance of 10…30 mm from it at the angle of 15°…45° to the longitudinal direction of the guide section. The weld joint shall be continuous at the transition into the end section extended sidewards, the said section shall be straight or bowed in the zone where the angle with the main section is formed.

EFFECT: weld joint provides for better strength of the connection and resistance to dynamic loads.
