Abstract

In a load weighing method for a wheel loader, an inclined angle of a ground surface on a slope where the wheel loader is working is detected. A change in a boom angle and a change in a pressure of a boom cylinder are detected while pivoting the boom and an attachment connected to the boom, wherein a load is placed on the attachment. Weight of the load is calculated using the inclined angle of the ground surface, the change in the boom angle and the change in the pressure of the boom cylinder as variables of a rotational dynamic equation for the pivot of the boom.

Description

technical field [0001] The present invention relates to a load weight measuring method and a measuring system of a wheel loader, in particular to a method of measuring load weight of a wheel loader working on an inclined ground and a measuring system for performing the above method. Background technique [0002] Wheel loaders are widely used to excavate, transport soil, sand, etc. at a construction site, and perform loading and the like to cargo vehicles such as dump trucks. [0003] However, the above-mentioned dump truck calculates the fee according to the amount of loading, and there is a possibility of paying a fine if the specified loading weight is exceeded. Not only that, loading more than the rated capacity of the bucket may be the cause of damage to the wheel loader. Therefore, it is necessary to accurately measure the weight of the load, so as to prevent the dump truck from being overloaded and save the maintenance cost of the wheel loader.
