AI Technical Summary
Technical Problem
Traditional seismic mitigation design mainly relies on increasing the overall strength of steel structures to resist earthquakes, but damage still occurs during earthquakes, and it increases manufacturing costs. Existing technologies lack effective seismic mitigation methods.
Method used
Vibration damping devices, such as liquid viscous dampers, lead-core rubber bearings, or seismic spring bearings, are installed between the main beams and columns to absorb seismic energy and improve the seismic resistance of the steel structure.
Benefits of technology
It effectively absorbs earthquake energy, reduces damage to steel structures, lowers repair and maintenance costs, improves earthquake resistance, and reduces post-earthquake inspection and maintenance time.

Abstract
This utility model discloses a vibration-damping rail crane, belonging to the technical field of rail cranes. It includes a main beam, a first column, a second column, and a vibration-damping device. The first column is installed at one end of the main beam, and the second column is installed at the other end. A support rod is installed at the lower part of the main beam, with one end connected to the first column and the other end connected to the main beam. The vibration-damping device is installed on the support rod. This design improves the overall earthquake resistance, prevents damage during earthquakes, reduces manufacturing costs, and significantly reduces the time required for maintenance personnel to inspect and maintain the entire rail crane steel structure after an earthquake.
