The invention relates to a boom structure (2) on a work machine (1). The boom structure (2) comprises at least two boom branches (2a, 2b) and a main boom structure (2c) extending from their convergence area (4) substantially in a working direction. Thus the boom structure (2) provides a fork-like structure.
