Abstract: An end treatment for a guardrail safety system includes a terminal portion of a guardrail beam comprising a downstream end and upstream end, a first tension cable coupled to an upstream end of the terminal portion. An extruder configured to receive at least a portion of the guardrail beam and at least a portion of the first tension cable, and a terminal support post installed adjacent the roadway at an upstream end of the terminal portion of the guardrail beam. The extruder includes a narrowing throat providing a channel in which at least a portion of the guardrail beam is disposed. The narrowing throat is configured to flatten the guardrail beam in response to a collision with a vehicle moving the extruder in a downstream direction along the guardrail beam. The terminal support post coupled to an upstream end of the first tension cable.

Abstract: According to a particular embodiment, an end treatment for a guardrail safety system includes a terminal portion of a guardrail beam comprising a downstream end and upstream end, a first tension cable coupled to an upstream end of the terminal portion. an extruder configured to receive at least a portion of the guardrail beam and at least a portion of the first tension cable, and a terminal support post installed adjacent the roadway at an upstream end of the terminal portion of the guardrail beam. The extruder includes a narrowing throat providing a channel in which at least a portion of the guardrail beam is disposed. The narrowing throat is configured to flatten the guardrail beam in response to a collision with a vehicle moving the extruder in a downstream direction along the guardrail beam. The terminal support post coupled to an upstream end of the first tension cable.

Abstract translation: 根据特定实施例，用于护栏安全系统的端部处理包括护栏梁的终端部分，该护栏梁包括下游端和上游端，第一张力线缆连接到终端部分的上游端。 配置成容纳护栏梁的至少一部分和第一张力电缆的至少一部分的挤出机，以及在护栏梁的端子部分的上游端处邻近道路安装的端子支撑柱。 该挤出机包括一个狭窄的喉部，提供通道，其中护栏梁的至少一部分被设置在该通道中。 狭窄的喉部构造成响应于与沿着护栏梁沿下游方向移动挤出机的车辆的碰撞而使护栏梁变平。 所述端子支撑柱联接到所述第一张力电缆的上游端。
