TALL42™ Movable Barrier System
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. 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 for installation 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 simple design of TALL42™ consists of 1117mm (44”) long elements measuring 1067mm (42”) high, linked together with connecting pins. Each element is just 457mm (18”) wide ensuring minimal encroachment into adjacent traffic lanes. The pin connection provides up to 20-degree movement between elements, achieving a minimum horizontal radius of 10.1m.
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 of TALL42™ allowing the entire safety barrier system to pass through the transfer machine.

TALL42™ FAQs
What are the advantages of using TALL42™ movable barrier?
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.
How does TALL42™ movable barrier work?
The reconfiguring of traffic lanes is undertaken using a transfer machine that lifts the interconnected TALL42™ units and repositions them as required by site geometry requirements. The transfer machine also prepositions the QUASH™ crash cushion maintaining a MASH compliant end-to-end safety barrier system.
Is TALL42™ movable barrier suitable for permanent locations?
Yes. 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.
Is TALL42™ movable barrier suitable as a temporary barrier?
Yes. 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.
