  • Page 5: System Overview

    The SLED End Treatment System is a gating, non-redirective crash cushion designed to shield the end of permanent and portable barriers made of concrete, steel, or plastic. The SLED End Treatment System is designed for uni– and bi-directional traffic flow applications (or on pp. 47-48).

  • Page 6: Product Overview And Function

    TL-3 crashworthy requirements of Report NCHRP 350. Attached to the front empty module is the patented Containment Impact Sled (CIS) which collects the ruptured debris in front of the impacting vehicle..

  • Page 7: Sled Identification And Orientation

    SLED Identification and Orientation Figure 2 (or on pg. 38) identifies the TL-2 SLED End Treatment Systems front and rear orientation for installation. Figure 3 (or on pg. 39) identifies the TL-3 SLED End Treatment Systems front and rear orientation for installation. The Containment Impact Sled orients the front. Module #1 attached to the shielded barrier orients to the rear.

  • Page 8: Product Components And General Specifications

    Two forklift pockets (slots) are designed into the modules, located at grade level, which can be used to insert forklift blades for moving the filled or unfilled SLED Modules sections as needed. The molded- in steel cables ARE NOT be to be used for lifting the modules. Only the two forklift pockets (slots) should be used to lift the modules as identified in Figures 4 and 5 (or on pp.
