The crane is used to lift various heavy objects and materials in the enterprise's freight yard and workshop. Sometimes in order to calculate the weight of the weight to be lifted, it is necessary to use a hoisting scale. The hoisting scale is an application of the steady technology in the crane. The editor today tells you the history and current situation of weighing technology applied to cranes.
Crane is a kind of handling equipment that lifts, lowers and moves materials horizontally in an intermittent operation. In order to enable the crane to complete the weighing of the hoisted materials while carrying out operations, people subsequently have the idea and desire to assemble a weighing device on the crane.
Cranes have applied weighing technology for more than 200 years. Located in the Bavarian State Bureau of Measurement in Munich, there is a wall spring weighing scale weighing suspended loads around 1780; in Hamburg there is also a 1760 fixed jib jib crane with a 1858 mounted on it. Manufactured decimal scale. In the first half of the 19th century, crane (crane) scales were known as the "Swedish ship scale". In 1932, the error of crane scales with slings could reach within 0.2% of any load, and the type approval was obtained.
With the breakthrough progress of digital technology, especially the progress of electronic weighing technology, the development of mechanization, automation, integration and intelligence of cranes has been promoted. Due to the continuous expansion of industrial production scale and increasing production efficiency, large-scale, high-speed and specialized cranes have the performance characteristics of automation, intelligence and information. The application of modern weighing technology has enabled various cranes to directly participate in the loading and unloading, transportation, lifting, sorting, stacking, storage and even distribution of materials in the operating environment, and sometimes they can directly measure, identify, track and manage materials. and many more.
At present, the weighing devices used on cranes can generally be divided into two categories: electronic crane scales and special weighing devices according to their functions. The widely used electronic crane scales have many related descriptions, so I won't elaborate on them here. The special weighing device mainly refers to the lifting weight limiter that has been commonly used on cranes . Lifting weight limiter is also called overload limiter. It is an important safety protection device on the crane.
With the development of science and technology, more and more technologies are applied to cranes, and the working performance of cranes will continue to improve, making it more convenient for customers to use.
