Product specifications

Performance under vehicle impact (passive safety):

100-NE-C-R-SE-MD-0

(according to EN12767:2019)

The Lattix® 4412 mast system can be used as mast for sign support, other information and surveillance equipment or other applications. The mast is delivered as a complete assembly including mast, base plate and top plate.

The mast is tested and approved according to:

EN 12899-1, Fixed, vertical road traffic signs
EN 12767, Passive Safety of support of structures for road equipment

Full-scale impact crash tests and simulations have been performed according to EN 12767 at a speed of 35 km/h and 100 km/h with 4,1 m mast length. Simulations show that the mast will have equal performance up to 6,94 m length.

Consequently, the mast is approved for maximal 6,94 m and minimal 1,5 m from the ground to bottom of sign. Due to the risk of the penetration of the windscreen of an impacting car, the untested reduced minimum height of the lower edge of the sign shall not be lower than 2,0 m. Lower installations may be used, but risk of windscreen penetration shall be evaluated.

The sign mounted to a single mast should not weigh more than 200 kg and needs to be dimensioned according to local wind loads.

All performance presumes sufficient foundation.
