Floating scaleplate and in-situte oil consumption test method for loader

The invention discloses a floating scaleplate and an in-situ site oil consumption test method for a loader. The floating scaleplate comprises a base and a scaleplate body, wherein a mounting hole is formed in the center of the base; the scaleplate body is vertically arranged in the mounting hole in the base; a cavity is also formed in the base. The invention also provides the in-situe oil consumption test method for the loader by virtue of using the floating scaleplate. According to the in-situe oil consumption test method, a measurement result is close to an actual situation, and; under the working efficiency of the same type in theunder same working conditions, the measured oil consumption amount within unit time is objective and real. T; the method is convenient to operate and use, and; can be used for checking moreover, the oil consumption data of a wheel loader can be conveniently checked in a construction site.
