Abstract

Engin de chantier comportant des moyens de roulement avec un châssis (ensemble pivotant) (1) portant un mât (2), muni d'un outil, par un moyen de liaison et de pivotement pour relever et abaisser le mât (2) autour d'un axe (3), avec des vérins (6, 7). Le moyen de liaison et de pivotement du mât comprend une embase (4) reliée au châssis (1) et portant l'axe de pivotement (3) du mât. Une bielle (5) est montée pivotante sur l'embase (4). Un premier vérin (6) relie la bielle (5) au mât (2) et un second vérin (7) reliant l'embase (4) à la bielle (5).

Figure 00000001
Construction machine comprising rolling means with a chassis (swivel assembly) (1) carrying a mast (2), provided with a tool, by a connecting and pivoting means for raising and lowering the mast (2) around 'an axis (3), with cylinders (6, 7). The mast connecting and pivoting means comprises a base (4) connected to the chassis (1) and carrying the pivot axis (3) of the mast. A connecting rod (5) is pivotally mounted on the base (4). A first cylinder (6) connects the connecting rod (5) to the mast (2) and a second cylinder (7) connecting the base (4) to the connecting rod (5).
