ABSTRACT:
A hanging bollard has a pivotally attached hanger which is capable of supporting a load by a line coupling device. A preferred form of the coupling device is spring loaded to allow detachment of the bollard cable from the load only when the coupler and load are supported by the hanger. The hanger is pivoted out of the coupler engaging position when the bollard is to be used as a conventional bollard.
