Cranes are the most used construction machinery nowadays, and they play an important role in the construction industry, port and dock loading and unloading of goods, and shipbuilding. Port cranes, grab cranes, cantilever cranes, gantry cranes, ship cranes, etc. each have their own advantages and are used in different occasions and play an important role.

A crane is a multi-action hoisting machine that vertically lifts and transports heavy objects horizontally within a certain range. Lifting machinery can be divided into light and small lifting equipment, lifts, cranes and overhead monorail systems according to different structures. Light and small lifting equipment mainly includes lifting blocks, spreaders, jacks, manual hoists, electric hoists and ordinary winches, most of which are small in size, light in weight and easy to use. They can be used alone, and some can also be used as lifting mechanisms for cranes.

There are many types of cranes, and their uses are also different, but they are all for the production and development of enterprises, to increase the speed of transporting goods, and to promote the development of the port economy. They also play an important role in the construction industry. Cranes involve many industries and are important mechanical equipment.

There are many crane manufacturers, but most small enterprises have not developed so well, and have even been eliminated by the society. Large and medium-sized crane enterprises have developed. Cranes are important machinery for engineering construction, and they are also widely used in port terminals. Port cranes are mainly used for handling, loading and unloading equipment, which promotes the development of port economy.

Some large-scale enterprises are introducing, digesting and absorbing the technologies and new methods of similar products from the world’s advanced industrial countries, popularizing and applying optimized design, designing towards modularization and generalization, and using fewer components to meet user needs to the greatest extent; The development of intelligence and information technology requires complete, systematic and large-scale development, the development of large-scale, high-efficiency, energy-saving, and special cranes to meet the requirements of product diversification, and effectively improve work efficiency and operational safety.

There are more and more crane companies, and the companies themselves must have a sense of crisis, seize market opportunities, strengthen the work of revising standards, and eliminate backward production capacity, which is conducive to participating in international competition and speeding up entry into the international market.
