MOTOR GRADER WORK EQUIPMENT Russian patent published in 2010 - IPC E02F3/76 

FIELD: transport.

SUBSTANCE: motor grader work equipment comprises blade consisting of central and two lateral sections and sections offset mechanism. In blade operation, lateral sections close before central section, their cutting edges staying below that of central section. Note here that that blade is elongated due to offsetting of lateral sections backward and sideway so that lateral and central sections form elongated blade. Sections offset mechanism comprises frame secured onto central section to secure levers and tie-rods that move lateral sections with respect to central section, thrusts to transfer loads from lateral sections onto central section and frame, and hydraulic cylinders that move lateral sections relative to central section.

EFFECT: reduced metal consumption, higher efficiency.
