Impact-resistant and energy-absorbing bollard system
A bollard system having a main post; a post collar; a base plate; and an energy-absorbing element. The base plate has an arcuate outer wall and inwardly projecting mounting fastener notches around the bottom of the base plate. The post, the post collar and the base plate are shaped such that when the post is loaded above the base plate, an obliquely, downwardly directed sliding movement of the post and post collar relative to the base plate is obtained and is damped by the energy-absorbing element.
