Abstract
Description
Technical Field
[0001] The present application relates to the technical field of weighing equipment, and in particular to a weighing trolley. Background Art
[0002] A handcart is a transport vehicle that is pushed and pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of handcarts continues to develop, handcarts are still used as an indispensable transport tool.
[0003] Traditional trolleys need to be weighed when transporting goods in a fixed quantity. Generally, they are equipped with a weighing system, such as a platform scale or a floor scale, and the trolley is pushed onto the weighing system for weighing. However, this weighing system needs to be built in a fixed place, which is very troublesome for the transportation of corresponding materials. The trolley can only weigh materials in a fixed place, which is inefficient. At the same time, in the existing technology, the storage basket is often placed directly on the trolley without being fixed. However, the storage basket is prone to shaking, tilting or even tipping over during transportation, which is not conducive to the handling of materials. Utility Model Content
