How tall is a 12 foot barrier?
The twelve foot x 34 inch tall barrier is a common Pennsylvania sized barrier. It is longer and taller than the common 10 footer, thus it weighs more. Jersey barriers can also be 12ft 6in in length x 32in tall. Essentially, the 12ft barrier will cover more ground with one piece than the 10ft barrier. However, you can only haul about 9 of the 12ft barriers per truck.

Why do workers stand back from concrete barriers?
Because they are not concrete, it can be argued that workers become more cautious about standing immediately behind a barrier, as they are prone to do with PCB’s. Empirical evidence suggests that a site worker will stand back from the temporary steel barrier as their own site safe work practice dictates, because they do not have the false sense of security that comes with portable concrete barriers.
What type of barriers are used for high speed construction?
Safety barriers should be used where the risk to drivers, road workers, pedestrians or cyclists is higher than if there is no barrier.

Portable Concrete Barriers have been in use ...
How much does the Defender 100 weigh?
The Defender 100™ is only 3.9 m long and weighs only 303 kg. With feet at 1.35 m (4’5’) when a barrier is lifted using a forklift there is a very small overhang, improving safety. On the road side, the same level of safety is achieved because it easy for one person with a lanyard to control a much lighter 3.9m temporary steel barrier compared the more cumbersome 1000kg 12-15m (40-50 ft) temporary steel barriers.
How to handle steel barriers?
Firstly, is the use of double slings from lifting points on the top of the barrier. This will require a crane operator and a spotter who will guide the barrier in to place. This means a 1000kg 12-15m (40-50 ft) piece of steel is airborne on a work site, next to a road, usually with just one person guiding it with a lanyard. The barrier is cumbersome and does not lend itself easily to manoeuvring.
