An arm cylinder bracket (7a) is connected to a lower plate (BP). An inner rib (21) is disposed inside an arm (7) and connected to the lower plate (BP) within a connection range (RA) between the lower plate (BP) and the arm cylinder bracket (7a) in a side view.

The invention relates to a stick (14) for an excavator, with a stick section (51) provided at the stick end (48), which is provided on a stick main section (50), with an mounting axis (17) provided at a stick end (48) of the stick section (51), on which an mounting device (21) with an attachment bearing point (38) of a coupling device (33) is pivotably mounted about the mounting axis (17), with a deflector axis (29) provided adjacent to the mounting axis (17) at the stick end (48), with a swivel kinematics (27), which comprises a swivel axis (35) on which a deflector (28) and a coupling (31) are jointly mounted, the deflector (28) engaging opposite the swivel axis (35) on the deflector axis (29) and the coupling (31) engaging opposite a coupling bearing point (37) of the coupling device (33), wherein a fork-shaped connection (20) is provided between the stick (14) and the mounting device (21) and/or between the swivel kinematics (27) and the mounting device (21).
