Operation
The WEDGE K12 Road Blocker is designed and built with the objective of preventing forceful
infiltration of vehicle. Any other use (e.g.: as a lifting device for loads or for jacking up vehicles) can
lead to unforeseen hazards to a third party or to damage and/or destruction of the blocker. It must
always be kept in the intended condition so that it does not become a possible cause of danger.
Any claim for manufacturer’s liability is barred if the blocker is used for any improper
operation or if a forceful attempt to enter the activated system is made.
(1) Only qualified and/or certified persons are allowed to operate the WEDGE K12 Road Blocker.
During operation no vehicles, goods or persons are allowed in the movement area of the
blocking element of the WEDGE K12 Road Blocker in order to avoid collisions and injuries.
(2) The system is to be operated in such a way that approaching vehicles have time to stop in
front of it. Every movement of the system’s blocking element must be carefully monitored.
(3) The tolerable impact load of the WEDGE K12 amounts to 1852 kJ. This is equivalent to the
impact force of an approx. 7.5 ton heavy vehicle with an initial speed of 80 km/h.
(4) The opening time of the blocking element averages about 4…5 seconds, the lowering time 4
seconds.
Optional: With the accumulator version the opening time is 1…2 seconds and the lowering
time 4 seconds.
(5) The standard control instructions are carried out using a push button switch “Open-Close-
Emergency stop”. Customer related controls are optional possible.
(6) The end positions of the blocking element are detected by proximity switches.
(7) The underground housing of the WEDGE K12 is certified for a wheel load of 100 kN
(correspond with 10 tons per wheel or 20 tons per axle) or alternative an area load of
33.3kN/m².
(8) The WEDGE K12 Road Blocker can be either operated using normal or manual operation via
hand pump. In normal mode it is operated with the help of a hydraulic drive which is fed by a
3 phase alternating current 230 / 400V 50 Hz.
(9) The WEDGE K12 is designed for outdoor operation and therefore can be used without
problem in outside temperature ranging from - 20°C to + 60°C. However attention needs to be
paid that the drainage of the housing (1) is assured in order to avoid damage or destruction of
the situated components. In winter during strong snowfall the area over the WEDGE K12
should be kept free of snow.
