Short summary
We developed a crane damper that uses a movable damping mass instead of concrete counterweights. This controls wind-induced swaying/twisting without causing space loss. Simulations show a reduction in swaying of ~49 % and movement of ~24 %. A mass ratio of 3 %–4 % yields the best results, safely maximizing control. The rear design matches the efficiency of medium-sized crane systems (75 %–91 %) while avoiding top-space conflicts – ideal for crane retrofits or space-constrained sites.
