A safety closing system for a shaft door panel of an elevator installation brings the shaft door panel into a closed setting in the absence of an opening force. The safety closing system includes a spring which is stressed in the open setting of the shaft door panel and a drive mass which is subject to gravitational force, the spring and mass being coupled by a flexible tension element with the shaft door panel.
