The Sentry Water Cable Barrier is an NCHRP 350 TL-3 certified work zone crash barrier that can be used as an alternative to cumbersom concrete barriers in a construction work zone. The Sentry has been tested and passed all TL-2 and TL-3 light and heavy vehicle impacts at 45 and 62.5 mph (70 and 100 kph). With eleven (11) interlocking knuckles on each end multiple Sentry’s can be linked together with a 1 ⅛” (30 mm) diameter galvanized hollow steel T-Pin with a steel keeper pin at the bottom of each T-Pin.
Molded into each Sentry are four (4) ⅜” (9.5 mm) diameter stranded steel cables, that are galvanized for excellent corrosion resistance. The cables prevent the impacting vehicle from penetrating the barrier wall and into the work zone or on-coming traffic.
The Sentry Water-Cable Barrier has been tested and accepted for all TL-1, TL-2, and TL-3 lightweight 1,807 lbs (820 kg) and heavyweight 4,409 lbs (2,000 kg) vehicle impacts at 45 mph (70 kph) and 62.5 mph (100 kph) impacts. Sentry can do any job, without the addition of external steel or extra parts, where water barrier is specified.
How? Sentry Water-Cable Barrier allows for the creation of a free standing continuous longitudinal water-cable barrier. Each Sentry wall section has four integrally molded corrosion resistant steel cables and eight (8) bushings connecting the barrier sections to prevent vehicle breaching. Weighing 2,000 lbs (907 kg) when filled, the Sentry Water-Cable Barrier softly absorbs the impacting vehicles energy progressively using water, and the steel cables to capture the vehicle without redirection, avoiding a secondary incident.
Errant Vehicles are…
- Prevented from entering the work zone,
- Captured and not redirected into traffic,
- Safely controlled and stopped,
Increasing the survival rate of occupants and workers!
