QUASH Crash Cushion

The QUASH™ Crash Cushion System is a high performance non-redirective, gating crash cushion designed to shield the blunt end of the TALL42™ movable concrete barrier. QUASH™ has been specifically designed for rapid deployment and ease of installation and does not require anchoring to the road foundation.

The simple design of QUASH™ consists of a nose piece, absorption cells and an end transition for connection to the downstream TALL42™ barrier, all linked together with connecting pins.

The preassembled absorption cells are filled with water reducing the severity of end-on impacts. The cells feature convenient dual lifting points and may be handled empty or filled. The self-centring J-slot hinge ensures QUASH™ remains correctly aligned with the TALL42™ movable barrier system as it passes through the transfer machine.

    QUASH™ Crash Cushion FAQs

    What is the QUASH™ Crash Cushion made of?

    QUASH™ is manufactured from linear low-density polyethylene offering excellent impact resistance and high tensile strength. The internal areas of the cells are free from corrodible components.

    How does the QUASH™ Crash Cushion work?

    QUASH™ has been assessed as a non-redirective crash cushion. Non-redirective crash cushions are designed to safely accommodate most vehicles striking the front of the cushion but have no capability to redirect vehicles impacting near the rear of the device. 

    The simple design of QUASH™ consists of a nose piece, absorption cells and an end transition to the downstream barrier, all linked together with steel connecting pins.

    The preassembled absorption cells are filled with water, reducing the severity of head-on impacts. The cells feature convenient dual lifting points and may be handled empty or filled. The self-centring J-slot hinge ensures the QUASH™ remains correctly aligned with the TALL42™ movable barrier system as it passes through the transfer machine.

    What is TALL42™ Movable Barrier?

    TALL42™ is a freestanding, movable concrete barrier system designed to be used with a transfer machine that can reposition the barrier altering the traffic lane configuration.

    TALL42™ is specifically designed to reconfigure traffic lanes, reducing congestion and improving the efficiency of existing road corridors. Unlike contraflows that rely upon bollards or flashing lights, TALL42™ provides positive protection, demonstrating safe vehicle containment and redirection in accordance with MASH TL4 and TL3.

    Does the QUASH™ Crash Cushion require anchoring?

    No, the QUASH™ Crash Cushion does not require ground anchoring.

    Is the QUASH™ Crash Cushion compatible with the TALL42™ Transfer Machine?

    Yes. The T-top shape of the absorption cells allows the QUASH™ Crash Cushion to be lifted when filled and gently set down by the transfer machine.
