Dual swing damper offers faster and more efficient working with crane and extended equipment lifetime. Swing damper effectively suppresses the longitudinal as well as the lateral fluctuations. The braking power can be adjusted by tightening the screws. Brake pad change interval is long, and the structure is fully protected against mechanical stress as well as dirt and dust. Swing damper can be connected retrospectively to all FR rotators and to multiple crane brands that are equipped with H-brackets. In case that the crane beam is an I-head model that does not have separate brackets, optional weld-on brackets are available. Installation is easy and requires no additional machining or welding. Lower end of the swing damper is connected directly to a rotator by sliding the rotator in to the brake slot. The upper end of the crane beam is measured and the measurements are reported in separate order form when ordering (measurement form). See also weldable boom head for swing damper.
