The present invention relates to an earthquake resistance reinforcement structure for a crane and, more specifically, to an earthquake resistant reinforcement structure for a crane which is installed between a wheel support plate on which crane wheels are installed and a crane support plate in order to support a crane which is installed in a port and unloads luggage. The earthquake resistance reinforcement structure for a crane comprises: a lower plate which is mounted on the top of the wheel support plate; an upper plate which supports the crane support plate by coming into contact with the bottom of the crane support plate, and is placed on the opposite side of the lower plate; and an attenuation unit which is installed between the lower and upper plates and attenuates tensile force due to the movement of the crane when an earthquake occurs. As a result, an earthquake resistant structure is included in a fixed or mobile crane to which an earthquake resistance design is not applied, and when an earthquake occurs, the kinetic energy of the ground is not transferred to the crane, therefore, the crane can be reinforced in order to prevent secondary damage. |
