Domestic development trend
In order to survive and develop in this field, there are still many things that Chinese auto crane manufacturers need to do in order to survive and develop in this field. Due to the increasing market demand, manufacturers are required to continue to innovate and develop continuously on the basis of ensuring the performance of cranes. New products with larger tonnages to meet market demand. Only in this way can we obtain nutrients and vitality from the market to survive, to develop in survival, and to grow stronger in development.
The main development trends should have the following:
Expand the variety of products
A perfect product research and development system should be established within the enterprise to make the product serialized and complete in variety. It is necessary to form a complete series of large, medium and small, increase the number of products, and expand the production scale.
Increase the lifting torque
At present, most of the automobile cranes produced in China are small and medium tonnage cranes of less than 50 tons, and the production of large tonnage is very small.
With the development of society, the demand for flexible and large lifting machinery is increasing. This is the nutrient for the development of automobile cranes.
So increasing the torque is imminent.
Increase crane function
With the rapid development of the national economy, users are increasingly demanding the use of truck cranes. It is hoped that they can be used more than one machine. It is not only used when carrying heavy loads, but also used in different environments and types of work. These are for future development
Find the direction.
Strive to build your own brand
At present, China's automobile crane manufacturers lack their own professional researchers and development teams, but instead imitate others' lives.
The finished product has no development direction and competitiveness. The globalization of the future economy and the series of problems caused by it will make the means of competition transfer from the traditional products and prices to the competition of brands. Therefore, major automobile manufacturers should strive to build their own brands, so that they can grow and develop.
Create a self-space occupation market
China's major automotive crane manufacturers must continue to innovate, boldly carry out operational and wise reforms, market-oriented, structure
Optimization, personnel reorganization, introduction of equipment, hard research and development, and the market under the premise of constantly improving themselves.
Foreign development trend
Computerization and automation of design and manufacturing
In recent years, with the widespread use of electronic computers, many foreign crane manufacturers have increased the application of crane assisted design systems (CAD) to application computers for module design of cranes. The modular design of the crane is not only a reform of the design method, but also affects the technology, production and management level of the entire crane industry. The replacement of old products and the development speed of new products will be greatly accelerated. For the improvement of the crane, only a few modules need to be changed; the design of the new crane requires only a new combination of different modules to improve the degree of generalization, and the single-piece small-batch product can be changed into a relatively batch module production. With fewer modules, they are combined into cranes of different specifications to meet the needs of the market and enhance competitiveness.
Innovation and application of crane control components
The positioning accuracy of the crane is an important requirement for the crane. Most of them adopt the corner code disc, the gear chain, the laser head and the steel plate hole to ensure the positioning accuracy is usually ±3mm. The accuracy higher than 1mm requires an additional positioning system. Improvements in crane hoisting speeds and brakes use precise positioning of the crane hooks at low speeds, and the crane's brake system also uses micro-processing for control and monitoring.
The remote control system is used for car cranes and other mobile cranes. The system includes a controller on the controller and a receiver mounted on the crane. The controller has an electromagnetic radiation generator, a receiver and a crane. The switching sections of the operating machinery of the transmission are connected. The use of the remote control not only saves manpower, improves work efficiency, but also improves the operator's working conditions.
The distance detection anti-collision device of the crane adopts a radio signal type anti-collision device. The anti-collision system is composed of a three-phase system for monitoring the distance of the front end of the crane. Generally, a signal warning is first issued, and then the vehicle speed is reduced to 50%. Finally, cut off the motor power and brake the cart.
