Vehicle leveling device and method

A vehicle leveling device for ensuring that a vehicle is level for calibration of sensors that are installed on the vehicle, wherein the vehicle comprises a plurality of wheels, the vehicle leveling device comprising:

• a lifting jack under each of the vehicle's wheels;
• a mounting clamp for mounting to each of the vehicle's wheels, each said mounting clamp further comprising:
• a sizing frame having two ends;
• a clamping member slidably mounted upon each end of said sizing frame;
• each said clamping member having at least two pivotally mounted engagement hooks;
• an actuating member on said sizing frame which draws said clamping members towards or away from each other such that said engagement hooks may grip or release the rim of the wheel to which said mounting clamp is mounted;
• and
• a support member mounted central to said sizing frame that supports an indicator for a liquid level that is in fluid connection with the other said indicators on all other said mounting clamps on each of the vehicle's other wheels with enough liquid that a level reading can be taken at each indicator;
• and
• wherein said lifting jacks may be actuated under each of the vehicle's wheels such that the height of the liquid in each said indicator is equal signifying that each wheel is coplanar and the vehicle is level.

A method for ensuring that a vehicle is level for calibration of sensors that are installed on the vehicle, wherein the vehicle comprises a plurality of wheels, comprising the steps of:

• placing a lifting jack under each of the vehicle's wheels;
• attaching a mounting clamp to each of the vehicle's wheels wherein each mounting clamp has a sizing frame having two ends, a clamping member slidably mounted upon each end of the sizing frame each comprising at least two pivotally mounted engagement hooks, an actuating member on the sizing frame which draws the clamping members towards or away from each other such that the engagement hooks may grip or release the rim of the wheel to which the mounting clamp is mounted, and a support member mounted central to the sizing frame;
• mounting of a telescoping leveling frame onto the support members of the mounting clamp on each of the vehicle's wheels wherein a telescopic leveling frame has a series of interlocking tubes arranged to form a frame that surrounds the vehicle and a plurality of bubble levels are mounted to the frame;
• actuating the lifting jacks under each of the vehicle's wheels until each bubble level on the leveling frame becomes centered indicating that each wheel is coplanar and the vehicle is level.

• filling the indicators with enough liquid that a level reading can be taken at each indicator;
• actuating the lifting jacks under each of the vehicle's wheels until the height of the liquid in each indicator is equal to each other signifying that each wheel is coplanar and the vehicle is level.
