Cabin for construction machine

A cab (10) has a hinge (29). A first element (31) of the hinge (29) is fixed to the side wall (19). A second element (32) is attached to a door (20). An intermediate member (33) is pivotally connected to the first and second members (31, 32) about first and second pivot pins (36, 37). First stops (41, 42) limit the pivoting angle between the first element and the intermediate element (31, 33) to a first angle. Second stops (43, 44) limit the pivoting angle between the second element and the intermediate element (32, 33) to a second angle. The full opening position of a striker (27) coincides with the engagement position of the side wall (19). In the fully open position, the pivoting angle of the opening / closing door (20) to be opened corresponds to the sum of the first and second angles. In the engaged position, the striker (27) is in engagement with the closing plate (28) arranged on the side wall (19).
