DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-weighting device for a truck, which can be installed on a truck and can measure the weight of a load such as gravel or crushed stone loaded on a bed of the truck or a mixed material such as asphalt mixture.

[0002]

2. Description of the Prior Art Conventionally, transportation of ready-mixed concrete material and asphalt mixture to a ready-mixed plant or asphalt mixture plant has been carried out using a dump truck.

[0003]

The transportation of ready-mixed concrete materials and the like in a conventional dump truck has been carried out by loading a dump truck having a loading capacity equal to or more than the legally-regulated loading capacity of the dump truck. However, the enforcement of laws and regulations has led to strict enforcement, and transportation must be carried out using a large number of dump trucks. However, expensive dump trucks are difficult to purchase and have the disadvantage of increasing transportation costs. Further, even if an attempt is made to transport using a normal truck without using a dump truck, there is a disadvantage that the weight of the luggage cannot be measured and the luggage cannot be used.

The present invention has been made in view of the above-mentioned conventional drawbacks,
With the aim of providing a self-weighing device for trucks that can be easily installed on ordinary trucks and measure the weight of the luggage loaded on the luggage carrier, and that can transport luggage such as ready-mixed concrete materials and asphalt mix materials like dump trucks I have. Another object of the present invention is to provide a weight meter for a truck having a simple structure and a small number of failures, which can be stored so that a measuring element does not operate when not in use, and can be positioned so that weight can be measured when in use. And

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the scope of the present invention.
