In this respect the best, the flexible design
with blade attached to a rubber element reduced
the wet retro of the marking by 20 runs less than
others by just a few runs. (Abstract

Helsinki 2000)

• Comments
• the best, the flexible design with blade
  attached to a rubber element ActiveAdapter
• The front plow in Finnish test was 14 ft
  reversible plow one 4 ft and two 5 ft steel
  blades was floated with ActiveAdapters (better
  flex would have been achieved by using 2 pieces
  of 4 ft and 2 pieces of 3 ft blades floating
  independently). Plowingtest has been made without
  any plow supporting.
• The first, a bit too stiff version of the
  ActiveAdapters was used in test.
• All current types (kt 445, kt 448 and pf 4) will
  flex now easier, upright.
• The total wear and tear (including normal wear)
  of the road markings and painted lines in
• Finland is over 10 000 metric tons and the
  repaintings costs are over 15 million euro,
• annually.

• Comments
• The front plow in Swedish test was 12 ft
  reversible, trip edge plow and the wing plow mold
  board was 15 ft wide. Both plows were supported
  with wheels.
• On the front plow 3 pieces of 4 ft steel blades
  were floated with ActiveAdapters (better flex
  would have been achieved by using 4 pieces of 3
  ft blades) and on the wing plow 3 pieces 4 ft and
  one 3 ft steel blade were floated (better flex
  would have been achieved here by using 5 pieces
  of 3 ft blades floating independendly)
• Total 28 measuring points/every bladetype 21

Why ActiveAdapters ?1) Look at the traditional,
rectilinear, rigid and unevenly worn blades (as
showed under)2) Think about the road markings
and markers installed 0,3...10 mm above
pavements, for traffic safety- The excessive the
wear on blades is the more excessive the wear and
tear damages on markings, markers, paintings,
pavements etc. are3) Compare the purchasing
prices of the traditional blades to repairing
costs of the markings and markers

Summa summarumActiveAdapters

blade-floating system

• The patented rubber-mounted ActiveAdapters,
  between the plow moldboard and blades, will
  change your rigid snowplow blades into a free
  floating, shock absorbing system, resulting in
  higher plow speeds, no damage to RPMs, extended
  life to painted road lines, reduced noise,
  vibration, shock, better snow removal on uneven
  roads with less salt and sand needed.
• Max allowed, independent upright-movement
  (blade-floating and/or shock absorption range)
  for every single blade is about 8,10 or 12 mm.
  Movement depends of blade-loading forces.
