Frequently Asked Questions
Q. What is the difference between a Standard and a Delineation Barrier?
A. The Standard Rhino Barrier can be used in conjunction with the NCHRP 350 Impact strips to be used where a TL2 is required or European needs where speeds do not exceed 50mph with a working width of W8. The Standard Barrier has more polyethylene used in its manufacture to meet these requirements.
Delineation barriers cannot be used in conjunction with the impact strips to the above criteria but it is more suited to general construction, special events, security. It is lighter as it uses less polyethylene in its manufacture.
Q. What is the length of the barriers when connected together and how many can I get in a 40' HC container?
A. The barriers are 2m or 6' 6" from pin to pin. If therefore you needed 100 linear metres of barrier you would need 50 units (300 linear feet would require 47 barriers). We can fit 76 Rhino Barriers into a 40' HC container (We ship 78 barriers in a 48' trailer or 102 in a 53' trailer).
Q. What are the deflection kits for and can fencing or lights be added to the barriers?
A. The deflection kits need to be fitted where the barrier must meet NCHRP TL2 criteria or BS/EN1317 parts 1 & 2 standard toW8. Lights can be fitted into the locking pin (click here for Lights). Fencing can also be fitted with a simple modification to the pins.
Q. How much water do I need to put in a barrier for a TL2 requirement? How long does it take to fill and empty a barrier and how do I stop the water freezing?
A. A barrier requires 350 litres or 77 gallons of water which takes around 15 minutes to fill with a standard garden hose and 7 minutes to empty. You can stop the water freezing by adding salt, calcium chloride or CMA (calcium magnesium acetate).
Q. What are the barriers made from and what colours are available?
A. Rhino barriers are rotationally moulded with the use of Polyethylene and UV protectors to provide one of the toughest plastic barriers on the market. As well as the standard white and orange, we can provide green, yellow or evergreen for delineation barriers (click here for Colours). If a specific colour is required, please Contact Us.
Q. What test levels have the barriers passed and what speed levels can they be used for?
A. The Rhino Barrier has been approved to NCHRP 350 TL2 and BS/EN1317 parts 1 & 2 to N1. The Rhino barrier has also had various certifications for use by the Highways Agencies in both the US and UK and additional various State approvals in the US. Which means that the speed limit for the NCHRP 350 requirement is 45 mph/70kph. For UK and European standard the speed limit is 50mph/80kph.
Q. How easily can the barrier be moved with and without impact strips?
A. When a barrier is empty it weighs only 55kg/120lbs and so is easily handled by two operatives. With impact strips the weight increases to 130kg/290lbs including all fittings but excluding water. If required the barriers can be moved by forklift using the fork slots moulded into the base.
Q. When the barrier is hit how much deflection is there and how many barriers
do I need?
A. Our MIRA test showed a deflection of just under 4m using a 2 ton pick-up hitting at an angle of 25 degrees with a speed of 69.2 kph. There were various other tests using a UK car at a speed of 80 kph to achieve BS/EN1317 Parts 1 & 2 to N1. The test criteria stipulated that we use 34 Rhino barriers for the test.
Q. What are the Donuts used for and are end caps necessary?
A. The Donuts can be used to secure the barrier to the ground with the use of bolts, providing a more permanent fixture if required. The donuts fit into the underside of the barrier. The barrier is locked to the donut with the locking pin which once turned through 90 degrees locks together. End caps provide a much more aesthetically appealing appearance to a row of barriers but are not essential.
Q. Can I store the barriers outside when not in use and what happens if I lose a locking pin?
A. Yes barriers can be stacked and stored outdoors. To stack the barriers simply place three barriers tightly next to each other, turn the next barrier upside down and place between to further barriers. Once you have five barriers together start a second tier, stacking them across the first level of barriers. The locking pins are manufactured so that they are semi-retractable. The only way to remove them is by actually damaging the locking tabs on the lower end of the pin. In the unlikely event you require a replacement pin they are available.
Q. What makes the Rhino barrier better than other barriers on the market?
A. There are three features that make Rhino barriers superior to other water filled barriers:
· The locking pin that connects the barriers extends through the entire barrier locking them more securely together.
· Once the barriers are locked together, they will pivot up to 45 degrees. Six barriers will form a complete circle with a 4.5m / 15ft diameter.
· Rhino barriers are manufactured in a state-of-the-art facility ensuring that the wall thickness of each barrier is ¼" (8mm) thick consistently throughout the barrier.
Q. Can I fill the barrier with sand or concrete?
A. Yes, but you won't get it out!!
