Title (EN) LOAD CARRYING STUCTURE AND METHOD OF MANUFACTURE THEREFOR
(FR) STRUCTURE PORTE-CHARGE ET SON PROCEDE DE FABRICATI0N
Abstract: front page image
(EN)A load carrying structure (10) is, for example, the stick (12) of an excavator or another work element having at least three load input locations (70, 72, 74). In operating the excavator, for example, failure of the stick can occur owing to side, torsional, bending and columnar loading through bucket (16), boom (14), and control element connections (18, 20, 76) at associated load input locations. A method for making the structure (10) includes connecting top and bottom plates (22, 24) and side plates (30, 32) which extend outwardly to define respective load input locations (70, 74) Other load input locations (72, 74, 144) are on a box structure (82) formed with the side and top and bottom plates (30, 32; 22, 24) The structure (10) has a more uniform construction, particularly without weld discontinuities, and resists input forces more effectively owing to the relationship of the load input locations to substantially overcome failures associated with such structures.
(FR)Une structure porte-charge (10) est, par exemple, le bras (12) d"un excavateur ou autre machine de travail ayant au moins trois points de charge (70, 72, 74). Au cours du fonctionnement de l"excavateur, il peut se produire un endommagement du bras du a une charge laterale, de torsion, de flexion et de compression par l"intermediaire du godet (16), de la fleche (14), et des liaisons des elements de commande (18, 20, 76) aux points de charge. Un procede de fabrication de la structure (10) consiste a relier les plaques superieure et inferieure (22, 24) et les plaques laterales (30, 32) qui s"etendent vers l"exterieur pour definir des points de charge respectifs (70, 74). D"autres points de charge (72, 74, 144) se trouvent sur une structure en caisson (82) formee avec les plaques laterales superieure et inferieure (30, 32; 22, 24). La structure (10) possede une construction plus uniforme, notamment sans discontinuite de soudage, et resiste aux forces plus efficacement grace a la relation entre les points de charge pour eviter les defaillances de ces structures.
