Characteristics and Development Trend of Modern Crane

2017-07-26

With the rapid development of modern science and technology, the expansion of industrial production scale and increase of degree of automation, crane is more and more widely used in the process of modern production, the function becomes more and more big, the requirement of crane is also more high, crane is experiencing a great revolution. So the continuous development and innovation of crane is the key.
The characteristics and development trends of the modern crane as follows:
1. Major products, Large-scale, high speed, durable and customized
Due to the industrial production scale expands unceasingly, the production efficiency is increasing day by day, the proportion of material handling cost gradually increase in the process of the production, prompting growing demand for large scale or high speed cranes.
Lifting capacity is more and more big, the working speed is become higher, and put forward higher requirements on the energy consumption and reliability.
Crane has become an important link in the automation production process.
Crane is not only good to use, easy maintenance, easy operation, and better safety, less failure, and with long average trouble-free working hours.
Industrial production mode and the diversity of user requirements, which make special crane market expanding, the variety is also constantly updated, with unique function to meet the special needs and to play the best effect.
The function of metallurgical special purpose crane, explosion-proof crane, anti-corrosion crane, insulation crane and special crane for rail, ship and vehicle are increasing continuously,the performance improve constantly, and adaptability is stronger than ever before.
2. Series products, modularization, combination, standardization, and practical
Use modular design to replace the traditional design method of the whole machine, making components and parts that have basic same function of crane have a variety of purposes, with the same connection elements and interchangeable standard module, through the combination of different modules, with fewer specifications parts to make multi species and multi specifications of the series of products, fully meet users’ requirements.
And forming cranes of different types and specifications.
3. Universal product, miniaturization, light-duty, facilitation and diversification
There are a batch of crane is used in the general workshop warehouses, demand is not high, work is not very heavy. So light duty crane and electric hoist overhead crane girder will have a faster development and replace most of medium and small tonnage bridge crane general purposes.
4. Product performance, automatic, intelligent, integrated and high efficient
The updating and development of crane depends mainly on the improvement of electric drives and controls. Combining automation technology and mechanical transmission technology, the advanced microelectronic technology, power electronics technology, optical fiber communication technology, hydraulic technology, fuzzy control technology are applied to the mechanical drive and control system, realizing automatic and semi-automatic.
Make the material handling system of crane has higher flexibility, so as to adapt to flexible production mode that more batch and less batch in the future.
5. Product portfolio, complete, systematical, compound and informationized
On the basis of crane single machine automation, through the computer forming a material handling and integration system, with the control of the central control room, combined with production equipment and coordinated with production system. This kind of crane automation degree is higher, with functions of information processing, to realize storage, arithmetic and logical judgment, transformation function that the information sensor detected, and then send a control instruction to actuator. This kind of crane also has good information input/output interface, achieve full, accurate and reliable information transmission in the material handling system.
6. Product design, micro-computerization, precision, rapidness and integration
With the wide application of electronic computer technology and and the development of modern design theory of system engineering, optimization of engineering, value engineering, reliability engineering, create a project, man-machine engineering, prompting emergence of many interdisciplinary modern design method and making the crane design into a new stage of innovation, high quality, high efficiency.
At present, the computer aided design (CAD) has been gradually into the design stages and various fields that design work involved.
Extreme state design, optimization design, reliability design, finite element method, modular design, reverse engineering design, fatigue design and robust design will be applied more thoroughly.
7. Product structure, new type, aesthetic, pleasant and comprehensive of product structure
The structural aspect adopts thin wall profile and special steel, reduce the stitching weld of the structure and improve the fatigue resistance.
Adopt various high strength low alloy steel new material, improve load bearing capacity, improve the stress condition, reduce self - weight and increase the good looking appearance.
To further develop new transmission parts and simplify mechanisms.
Develop speed regulation system and then control system with high performance, low cost, high reliability in electric control and development of semi-automatic and automatic control.
Adopt the integration technology of machine, electric, instrument and liquid, improve the performance and reliability of the machine, and increase the function of crane.
8. product manufacturing, flexbile, quick and excelsior
Manufacturing flexibility is to make the process equipment and process route can be suitable for the need of the production of various kinds of products, changing from current order mass production methods to many varieties of small batch production.
The flexible and quick production shortens the product time to the market, so that the enterprise mechanism can be flexibly turned.
The excelsior process of production and manufacturing to improve the labor productivity in the production process, maintain the product with stable quality, and emphasize the close cooperation between the various departments of the enterprise.
Good production mechanism and management mechanism are the premise of enterprise development.
