A hoisting crane includes a slew bearing. The slew bearing includes a top bearing ring, a bottom bearing ring, a first row of axial load rollers and a second row of axial load rollers, which rows of axial load rollers are provided between a corresponding top roller raceway and bottom roller raceway. The top bearing ring has a top wall which extends above the first row of axial load rollers and in which at least one top entry port is provided. Furthermore, the top roller raceway of the first row of axial load rollers includes a removable raceway segment releasable attached in the top entry port. The removable raceway segment can be removed to enable access via the top entry port to the first row of axial load rollers to remove axial load rollers in a substantially vertical direction.
