FRAME CATCHER ADAPTATION FOR GUARDRAIL EXTRUDER TERMINAL

摘要

Apparatus and methods are described for preventing penetration of vehicles (110) by causing the guardrail extruder terminal (82) to contact and engage the frame or chassis of even smaller vehicles in a collision. A guardail extruder terminal and treatment (82) is adapted for operation during impacts by attachment of a frame catcher penetration guard (80). The frame catcher adaptation extends below the usual lower edge of the impact head which presents an expanded contact area, the location of which approximates the location of a portion of the vehicle's chassis. In an alternative embodiment , a frame is provided which is affixed to a standard impact head. The frame includes a downwardly extending portion which presents the expanded contact area. The frame catcher devices described may readily be retrofitted onto existing guardrail extruder terminal impact heads (20).
