Abstract:
1. A barrier system for stopping vehicles, the barrier system comprising: an anchoring system; at least one end support attached to the anchoring system, wherein the end support comprises at least one vertical support; at least one energy absorption unit supported by the vertical support; a gliding bar that selectively defines an unfixed mode wherein the gliding bar is moveable relative to the energy absorption unit and defines a fixed mode wherein the gliding bar is fixed relative to the energy absorption unit, wherein the gliding bar is selectively convertible between the unfixed mode and the fixed mode and wherein the gliding bar defines a net end and a distal end opposite the net end; a net system connected to the net end of the gliding bar; and at least one gliding bar retainer for selectively fixing the gliding bar relative to the energy absorption unit when the gliding bar defines the fixed mode such that the gliding bar retainer remains locked and moveable with the gliding bar during energy absorption.
