CB FACT SHEET

Crash Barrels are manufactured from High Density Polyethylene plastic.

The barrels are filled with sand and positioned in an array layout to provide a vehicle crash cushion to protect the driver from hitting an unmoveable structure such as a barricade, bridge support or during roadwork construction.

PRODUCT

The barrels are covered with a plastic lid and have a lifting flange to attach a lifting ring to move the barrels.

Three sizes are available

• large holds 960kg of sand
• medium holds 640kg
• multi 320kg

The multi barrel is assembled on site by locking two different sizes of half-barrels together and filling to one of the three different fill heights.

CONSTRUCTION

The barrels are roto-moulded and have minimal variation in weight, dimensions, physical properties and colour.

MATERIALS

Barrels are manufactured from high-density polyethylene plastics, with UV stabilization, hindered-amine light stabilizer. Barrels are manufactured with three layer structure, the centre layer is formed using a chemical blowing agent, and the outer and inner layers are coloured yellow using dry blend yellow colorant.

SURFACE CONDITIONS

Inspect the area where the crash barrels are to be placed. The area must be concrete or asphalt, with a grade of no more than 3 degrees.

There are different array layouts from 50kph to 110kph. All barrel arrays are tested to NCHRP 350. Contact VMSI for test results.

ARRAY LAYOUT

• Review the plans and determine the centre line for rows of barrels
• Mark the centre line with chalk
• Position the lids of the barrels centered on the line with correct pacing between lids
• Mark around the lids with chalk
• Position the sand barrels in the correct positions, and replace lids
