Abstract

The invention relates to a weighing and measuring system of a tyre type container crane, which aims to solve the problem that containers at a harbor cannot be weighed in a lifting transfer process. The weighing and measuring system of the tyre type container crane comprises the tyre type container crane and also comprises the weighing and measuring system, wherein the weighing and measuring system comprises a weighing sensor, a signal conversion device, a control device, a weight display device and a data transmission and processing device; the weighing sensor is connected with the input end of the signal conversion device; the output end of the signal conversion device is connected with the inputs ends of the control device and the weight display device; and the output end of the weight display device is connected with the data transmission and processing device. The weighing and measuring system has the advantages that: the containers are transferred and weighed at the same time andthe work of the harbor is simplified, so that a great economic value is created; and the weight capacity of each steel wire cable is supplied with overweight protection and alarm.

Description

technical field [0001] The invention relates to the field of port equipment manufacturing, more specifically, the invention relates to a tire-type container crane weighing and measuring system for container lifting. Background technique [0002] At present, my country's foreign trade is developing continuously, especially after joining the World Trade Organization, the volume of import and export goods continues to increase rapidly. How to more accurately measure the volume of import and export goods is essential to ensure that the national tax collection is fully collected, to eliminate irregularities in the process of import and export declarations, to deepen the fair implementation of the tax rebate policy for enterprises in bonded areas, and to improve the data management of trade statistics and business statistics. It is of far-reaching significance to establish a rigorous and effective data quality assurance mechanism. [0003] Since all import and export containers n...
