Detailed Description for Motor Grader

A grader, also commonly referred to as a road grader, a blade, a maintainer, or a motor grader, is a construction machine with a long blade used to create a flat surface during the grading process. Typical models have three axles, with the engine and cab situated above the rear axles at one end of the vehicle and a third axle at the front end of the vehicle, with the blade in between. In certain countries, for example in Finland, almost every grader is equipped with a second blade that is placed in front of the front axle.

Graders are commenly usde as construction and maintenance od dirt roads and gravel roads. In the construction of paved roads they are used to prepare the base course to create a wide flat surface for the asphalt to be placed on. Graders are also used to set native soil foundation pads to finish grade prior to the construction of large buildings. Graders can produce inclined surfaces, to give cant (camber) to roads. In some countries they are used to produce drainage ditches with shallow V-shaped cross-sections on either side of highways.

The availablity and performance  will vary with the models from different companies. 

Standards (IS/ISO 7134 : 1993):-

Base machine: Grader without equipment, as described by the manufacturer’s specifications, but provided with the necessary mountings to secure the attachments.

Equipment: Set of corn ponents mounted onto the ba se machi ne to fulfil the p rimary design function.

 

Attachments: Optional assembly of components that can be mounted onto the base machine for a specific use.

 

Component: Part or an assembly of parts of a base machine, equipment or an attachment.  

Ripper: Attachment which consists of a frame connected to the rear part of the base machine by means of a mounting bracket. It is equipped with one or more teeth.  

Operating mass: Mass of the base machine, equipment specified by the manufacturer, operator (75 kg), full fuel tank and full lubricating, hydraulic and cooling systems.

Shipping mass: Mass of the base machine without operator, with full lubricating, hydraulic and cooling systems, 10 % of fuel tank capacity and with or without equipment, cab, canopy, ROPS) or FOPS*), as stated by the manufacturer.

 

Maximum travel speeds: Maximum speeds that can be obtained on hard level surfaces in each of the forward and reverse gear ratios available. 

Blade height, H19: Dimension obtained by measuring the distance on the 2 coordinate from the lower edge of the cutting edge to the top edge of the blade, measured at blade mid-length.

 

Shoulder reach, W9: Distance from a Y plane through the outside surface of a front tyre to a Y plane through the outermost point on the end of the blade, cutting edge or end bit with the lower edge of the cutting edge being maintained on the GRP and in an X plane, with no blade sideshift and wheels not leaned. For machines having crab steer capability, the manufacturer may specify an additional amount of reach available.

Lift above ground, H20: Vertical height from the GRP to a 2 plane containing the lower edge of the blade cutting edge when this edge is in an X plane. If blade pitch is adjustable, blade pitch angle is adjusted for maximum lift above the ground.

Circle sideshift, W14: Distance on Y coordinate between the zero Y plane and a Y plane through the centre point of the circle when the circle has been shifted to a position to the left or right of the zero Y plane.

Blade length, W8: Overall length measured between parallel vertical planes passing through the extreme ends of the blade or cutting edges or end bits, whichever is longer.

Circle sideshift, W14: Distance on Y coordinate between the zero Y plane and a Y plane through the centre point of the circle when the circle has been shifted to a position to the left or right of the zero Y plane.

Blade sideshift, W15: Offset from the middle position of a blade which is movable, with respect to the circle, along a line parallel to an element lying along the length of the blade

Blade Angle:Angle between a vertical plane through the lower edge of the cutting edge and an X plane.  

Blade base, L12: Distance on X coordinate between an X plane through the centreline of the front wheels and an X plane through the front edge of the cutting edge with the edge on the ground reference plane (GRP). If the blade pitch is adjustable, the blade pitch angle is to be at the mid-point of the adjustment. 

Blade pitch angle, AlO: Angle between the plane containing the forward surface of a flat cutting edge, or tangent to the forward surface at the bottom edge of the curved cutting edge, and the GRP when the lower edge of the cutting edge is on the GRP.

Wheel lean angle, Al 2: Angle between a vertical plane and a plane through a surface of the wheel rim when the wheel is in a lean position,
