Abstract: A tower (1) having equipment (3) mounted thereon is disclosed. The tower (1) has an ice shield assembly (2) for protection to of the equipment (3) against falling ice mounted thereon. The ice shield assembly (2) comprises a tower fixture arrangement (5) being secured to the tower (1) and an ice shield (4) connected 5 to the tower fixture arrangement (5) via a hinge (6). The ice shield (4) is configured for vertically overlapping the horizontal extends of the equipment (3). The ice shield assembly (2) further comprises at least one spring element (7), e.g. in the form of a curved rod, connected at one end to the ice shield (4) and at an opposite end to the tower (1), the at least one spring element (7) 10 being configured to allow the ice shield (4) to pivot relative to the tower (1) at the hinge (6) in order to ensure a gradual transfer of energy from falling ice, which collides with the ice shield (4).
