TALL42™ Movable Barrier System

MASH TL4 Concrete 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™ 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 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.

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.
