TALL42 is a freestanding, movable concrete road barrier system designed to be used with a transfer machine that can reposition the barrier, altering the traffic lane configuration. Developed by Moovop Inc. of Canada, TALL42 has been full-scale crash tested to MASH Test Level 4 and Test Level 3.
TALL42 has been specifically designed for contraflow applications on high-volume traffic roadways, allowing road owners to increase lane capacity during peak periods. In addition, TALL42 may be deployed on construction projects, reducing lane closures during non-work periods.
The T-top shape allows the TALL42 units to be lifted and gently set down by the transfer machine with an offset distance up to 9.1m. The transfer machine can reposition 1km of TALL42 barrier in just 8 minutes.
TALL42 is compatible with the MASH TL3 crash-tested QUASH Crash Cushion, providing a MASH-compliant end-to-end solution. QUASH is a water-filled barrier manufactured to the same shape as TALL42, allowing the entire safety barrier system to pass through the transfer machine.
TALL42 & QUASH have been recommended for acceptance by the Austroads Safety Barrier Safety Panel (ASBAP).
Category Manager, Ben Lorne, comments, “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 under MASH TL4 and TL3.
For permanent locations, TALL42 can be repositioned to meet peak traffic demands, increasing roadway capacity and reducing travel times. The system height of TALL42 reduces headlight glare into adjacent traffic lanes and provides driver confidence.
For temporary locations, TALL42 reduces construction time and minimises disruption to traffic with lanes closed to traffic during working hours that can be reopened during non-work periods. In addition, the rapid repositioning of the barrier allows contractors to more effectively manage changing traffic patterns and the progress of construction throughout the site.”
