A METHOD FOR DETERMINING A STATUS OF A DUMP BODY ARRANGEMENT

The invention relates to a method 100 for determining a status of an intermediate support (34) of a dump body arrangement (20) comprised in a working machine (1), the dump body arrangement comprising a support frame (24), a dump body (22) for receiving a load and pivotally attached to the support frame at a rear pivot point (32), a hydraulic support (36) for raising and lowering a front part (21) of the dump body, wherein the intermediate support (34) is arranged between the hydraulic support and the rear pivot point to support the dump body, wherein the method comprises the steps of receiving (110) a signal indicating that the hydraulic support changes between a load-free state and a loaded state relative the dump body; if the hydraulic support changes from the loaded state to the load-free state relative the dump body, determining (120,120a), when the hydraulic support is in the load-free state, an angle (α1) of the dump body relative the support frame; and/or if the hydraulic support changes from the load-free state to the loaded state relative the dump body, determining (120, 120b), when the hydraulic support is in the loaded state, any one of an angle (α2) of the dump body relative the support frame and a hydraulic pressure (p) in the hydraulic support; and determining (130) the status of the intermediate support by comparing any one of the determined angles and the determined hydraulic pressure with a corresponding threshold. L'invention concerne un procédé 100 de détermination d'un état d'un support intermédiaire (34) d'un agencement de benne basculante (20) comprise dans une machine de travail (1), l'agencement de benne basculante comprenant un cadre de support (24), une benne basculante (22) destinée à recevoir une charge et fixée de manière pivotante au cadre de support au niveau d'un point de pivotement arrière (32), un support hydraulique (36) pour élever et abaisser une partie avant (21) de la benne basculante, le support intermédiaire (34) est disposé entre le support hydraulique et le point de pivotement arrière pour supporter la benne basculante, le procédé comprenant les étapes consistant à recevoir (110) un signal indiquant que le support hydraulique change entre un état sans charge et un état chargé par rapport à la benne basculante ; si le support hydraulique change de l'état chargé à l'état sans charge par rapport à la benne basculante, déterminer (120 120a), lorsque le support hydraulique est dans l'état sans charge, un angle (α1) de
