Adjusting the RELAX -blade system
RELAX -release mechanism keeps the blades locked. The plowing result is even and formation of packed snow
decreases. When the blade hits an obstacle the release mechanism opens allowing the blade frame to turn backwards
and the blade to go over the obstacle. The system protects the driver, the plow and the base machine from damaging.
Plows with RELAX -blade system can be pressed down to remove packed snow.
Operation of the RELAX -blade system
-
Blade frame is mechanically locked in position by three joints (picture 17)
-
When the blade hits an obstacle, the increased pressure releases the lock
and the blade frame swivels in a
quick and wide motion over the obstacle (picture 18)
-
When the obstacle is passed, and pressure returns to normal the spring pushes the blade frame back into the
locked position (picture 17)
