METHOD TO INCREASE ADHESION WEIGHT OF TRAILED SCRAPER Russian patent published in 2008 - IPC E02F3/64 

FIELD: transport engineering.

SUBSTANCE: invention relates to methods of changing of vertical load on traction and transport vehicles. Proposed method to increase adhesion weight of tractor of trailed scraper comes to changing angle between draft pole and gooseneck. Angle between draft pole and gooseneck is set larger than necessary for complete separation of scraper front axle from ground h>0 and then length of draft pole is reduced to maximum.

EFFECT: provision of maximum increase of adhesion weight of trailed scraper at digging and preservation of maneuverability of trailed scraper at transportation.
