Abstract

L'escavatore presenta un sottocarro (1) e un sopracarro (4) disposto su di esso a guisa di supporto per i gruppi di comando e per il sedile (5) del conducente. Sul carro superiore (4) è articolata una trave (7) a due bracci. L'asse di inclinazione (15) della trave (7) a due bracci, portato da un cavalletto di supporto (14), è perpendicolare al piano di inclinazione di questa trave (7). Il carro superiore (4) è in grado di ruotare rispetto al sottocarro (1) di 360° per mezzo di una corona girevole (3) ricavata tra di essi. Il cavalletto di supporto (14) con l'asse di inclinazione (15) della trave (7) può ruotare intorno a un asse orizzontale (20), disposto nel piano di inclinazione dei bracci (8, 9) della trave, perpendicolarmente all'asse di inclinazione (15). Il cavalletto di supporto (14) con l'asse di inclinazione (15) della trave (7) posta sul lato del carrello superiore è parte di una corona girevole (17) la quale presenta un asse di rotazione orizzontale (20). Questa corona girevole (17) la quale presenta un asse di rotazione (20) orizzontale presenta una guida idraulica della rotazione disposta centralmente e sulla quale sono collegati i condotti tubolari per la sollecitazione delle unità (11, 13, 16) a stantuffo - cilindro per l'azionamento e per la regolazione dei bracci (8, 9) della trave (7) ovvero del mezzo di lavoro (12) (figura 2).The excavator has an undercarriage (1) and an overbody (4) arranged on it as a support for the control units and for the driver's seat (5). A two-arm beam (7) is articulated on the upper carriage (4). The inclination axis (15) of the two-arm beam (7), carried by a support stand (14), is perpendicular to the inclination plane of this beam (7). The upper carriage (4) is able to rotate 360 ° with respect to the undercarriage (1) by means of a rotating crown (3) formed between them. The support stand (14) with the inclination axis (15) of the beam (7) can rotate around a horizontal axis (20), arranged in the inclination plane of the arms (8, 9) of the beam, perpendicular to the inclination axis (15). The support stand (14) with the inclination axis (15) of the beam (7) placed on the side of the upper carriage is part of a rotating crown (17) which has a horizontal rotation axis (20). This rotating crown (17) which has a horizontal rotation axis (20) has a hydraulic rotation guide arranged centrally and on which the tubular ducts for stressing the piston units (11, 13, 16) are connected - cylinder for the actuation and for the adjustment of the arms (8, 9) of the beam (7) or of the working means (12) (figure 2).
