Crane Design Technology

Cranes have changed a lot in the past few decades. Although some operators still adhere to the original operation mode on lifting equipment that has been used for many years, some people have taken a step ahead and learned to use the advantages of the latest crane technology.

Fortunately, you do not need to buy an overhead bridge crane again to benefit from the latest technology. Next, we look at two simple, cost-effective, small-scale retrofits that will make your existing cranes safer, more efficient, and lower operating costs, even if your crane has been around for decades.

LED lighting upgrade
Can make your crane safer
At the same time, you save up to 80% in energy costs
and this is one of the quickest and most economical methods

Because of the lack of overhead light in the factory, which is often blocked by cranes, industrial cranes are usually equipped with lighting facilities. Standard cranes equipped with incandescent lamps, high-pressure sodium lamps or halogen lamps are helpful for lighting, but due to the divergence of the light emitted from them, the operator of the crane from the side can easily look directly at the lights, weakening the s/he sees the lifting of the goods. vision.

The LED lighting is different. Their high concentration of light greatly reduces the risk of blinding by operating lights, making it easier for operators to focus their attention on lifting goods and avoid obstacles. Moreover, like traditional types of lighting, LED lamps do not require long (up to 20 minutes) cooling before restarting. You can turn it off as needed. When you replace the existing lighting equipment on the standard 10-ton industrial crane with LED lamps, you can save up to 80% of the energy consumption for the crane. In general, the maximum power motor is a hoist motor, and the hoist motor is not continuously driven, so most of the energy consumption is in lighting facilities. Large cranes can also save 40-50% of the energy costs of the entire crane.

Other benefits: LED lights are instantly lit, long life, and do not need to be replaced as frequently as traditional lighting. At present, the new generation of LED lamps has a service life of up to 10 years under normal use. In contrast, standard lighting is more easily damaged by vibration and normal use, and it may need to be replaced every two to four years.

Refitting a crane with LED lighting is quite simple. If the crane is already equipped with lighting, just replace the light elements and switches. Due to the low energy consumption of LEDs, existing transformers are usually sufficient. If the crane is not currently equipped with lighting facilities, We can provide transformers, relays and all necessary components as well as installation instructions. Either way, replacements, and upgrades usually take less than a day. If you do not want to replace it yourself, technicians can help.

Remote upgrade
A simple ergonomic change
You can change your crane and workflow

How many of us get up to tune in the television channel? Running out. We use an easy-to-use remote control on our comfortable sofa or recliner. However, tens of thousands of cranes all over the world are still using communicators to control equipment. The operator must leave the Communicator position to operate the load and then move back to the Communicator position to move the load – coming and going back and forth numerous times a day.

If your operator can use the remote control at any time, how long can he save? More importantly, the remote control provides the operator with the safest way to operate the crane and the best field of view without being limited by the length of the communicator cable or the position of the mobile.

The operator can make faster, better and safer choices and move the crane to the best position. In some cases, the remote control can help the operator to perform certain tasks independently without the need for operators and assemblers to work together. When the plant crane covers a long period of time (sometimes 100 meters or more), the advantages of the remote control are even more pronounced.

Most standard cranes can complete remote control conversions in one day or less. The CXT crane’s remote control and communicator use the same plug, so the upgrade plan is very simple. We can also modify remote controls for cranes with single and double hoists manufactured by other crane manufacturers, such as standard cranes, heavy-duty cranes and fine-manipulated cranes.

Each manager has the best understanding of the operation processes and processes of his factory
Why don’t you think about the efficiency of these two upgrades for your work?
What impact will it have?
It can be said with certainty
If you try to use LED lights or remote control on the crane
Then you will get the benefits of energy saving and safer
And there are opportunities to increase your productivity

Electromagnetic Crane is a kind of lifting machine that uses electromagnetic principles to carry steel articles. The main part of the electromagnetic crane is the magnet. Switch on the current, the electromagnet steel items to absorb, transport to the designated place. Cut off the current, the magnetism disappears, and the steel stuff comes down. Electromagnetic crane is very convenient to use, but it must be used with the current. It can be used in waste steel recovery department and steelmaking workshop.

The device that uses electromagnets to carry steel materials is called an electromagnetic crane. The electromagnetic lifting bridge crane can generate strong magnetic field force, tens of tons of heavy iron, iron wire, nails, scrap iron and other kinds of iron materials, cannot be packed or packaged, and can be easily collected and transported. It not only saves labor but also simplifies work. Steel materials and machines in wooden cases can be carried in the same way. When the crane works, as long as the electric current in the electromagnetic iron wire does not stop, the weight that is sucked will not fall and the invisible magnetic force is more reliable than the solid chain.

If for some reason, cut off electricity, it will cause accidents, so some electromagnetic crane is arranged on the steel claw, to lift heavy objects transported, sturdy steel claw will automatically fall down tightly clasped them. Block crane can’t carry hot because the steel cannot be magnetized at high temperature. The electromagnetic crane can lift nearly 100 tons of weight in one stroke. The diameter of the electromagnet in the diagram is about 1.5 meters. It can bring up 16 tons of objects.

On February 21, 2008, the People’s Republic of China General Administration of quality supervision, inspection and Quarantine issued the “Crane Safety Technology Supervision Regulation – bridge crane“. The sixty-sixth electromagnetic crane’s lifting electromagnet shall be powered by a special circuit. Electromagnetic hoist should be able to guarantee the power supply of electromagnetic hoist when it loses electricity when it works.

Any detailed information you want to know about this kind of electromagnetic crane, welcome to contact us.

How to make the crane equipment to perform its maximum efficiency

With the increasing degree of lifting mechanization, the wide application of equipment not only accelerates the construction progress but also improves the quality of the construction.Since the  lifting equipment is affected by various factors during the daily use, the performance of the equipment cannot be fully played.What should we pay attention to in our daily construction to maximize the performance of the equipment?

The construction unit shall make good rules and regulations for the equipment manager, and maintain the normal construction order of the unit. Especially for the units with the frequent mobilization of equipment and personnel, a sound management system material shall be established.

Crane manufacturers should supervise relevant staff to carry out the maintenance and repair system and safety operation rules, so as to ensure the safety and reliability of the equipment and personnel.In the equipment management, many units often have the concept of heavy use and light maintenance, which will easily bury the safety hazard to the equipment.

The operation of the hoisting equipment is not standardized, which will aggravate the wear and aging of the equipment.Some units still employ nonqualified drivers, which not only cause early damage to the equipment but also seriously delay the normal construction period.

In order to make the equipment most effective in the long run, besides the daily maintenance work, we also need to pay attention to the replacement and repair of equipment damaged parts, which can be eliminated at the beginning of the failure and avoid the safety threat to the construction workers.

There are uncertainties in the future of heavy equipment. With the development of social economy, the scale of production is expanding, and the degree of automation products is higher and higher. Crane is widely applied in the modern production process, and the application area is also widespread.One of the key development priorities of many industrial developed countries is the lifting of heavy transport technology.Analysis of development situation in 2011 lifting transportation equipment, “NPC and CPPCC” during the hot topic of concern in the heavy machinery industry is for stability, in the relatively stable market environment, should be on the basis of this, to improve the quality of hoisting equipment, in a stable domestic sales at the same time, should also be to expand the overseas market.Crane is the basic equipment of the construction industry and manufacturing industry. In recent years, the country has made great efforts to develop infrastructure construction, and all of them need a lot of high quality.

General bridge crane working situation

Single beam crane is widely used in factories, warehouses, materials and other occasions to lift goods, and it is forbidden to be used in the flammable, explosive and corrosive medium.

There are two forms of operation on the ground and in the air.The ground operation has two kinds of handle operation with line handle and the handle of the remote control. The air operation refers to the operation of the driver’s room.There are two kinds of the cab, open and closed, which can be divided into the left or right side installation according to the actual situation. The two forms have two kinds of entry direction: side and end, so as to meet users’ needs under different needs.

Single beam crane is widely used in machinery manufacturing workshop, metallurgical workshop, petroleum, petrochemical, port, railway, civil aviation, power station, paper making, building materials, electronics and other industries workshop, warehouse, material yard, etc.It has the advantages of compact shape, the low height of building clearance, light self-weight, small wheel pressure and so on.

Some enterprises, industries, and regions that started restructuring earlier will gradually accelerate the recovery. Technology leads the future, innovation drives development. So, what are the major trends in the construction machinery industry technology trends? Modular design and virtual manufacturing Modular design includes the previously mentioned components.

Construction machinery gradually began to pick up in 2017, but the uncertainties that affect the economic operation of the industry still exist. Experts predict that the machinery industry will still undergo a severe test. With the gradual attainment of the national macro-control policy, the macroeconomic situation will gradually improve, the downward trend in the machinery industry will gradually stabilize, and the positive factors in the development of the industry will also accumulate. Some enterprises, industries, and regions that started restructuring earlier will gradually Accelerate the recovery. Technology leads the future, innovation drives development. So, what are the mainstream technology trends in the construction machinery industry?

First, the modular design and virtualization manufacturing

Modular design includes the previously mentioned part of the generalization and design of software modules. Modular design software allows different systems or components to be assembled on the computer and change parameters, which greatly accelerated the design of new product development progress. Information technology and the global economy have created the conditions for the virtual manufacturing of machinery manufacturing. Among the major multinational construction machinery companies, a clear trend is for manufacturers to focus their efforts on research and development and assembly of equipment, not manufacturing parts, and pushing it to parts suppliers. Host product manufacturers and component suppliers and research and development institutions to work together to play a creative spirit of all parties to jointly develop and produce marketable products.

Second, the coexistence of personalized and multi-functional

The different types of engineering, materials, scale and different construction environment put forward the requirements of individualization and multi-function for construction machinery. The development of modern design technology and flexible manufacturing technology also created the conditions for the realization of product individuation and multi-function. Personalized products are adapted to a particular situation and appear, and a multi-purpose construction machinery is the development of another direction, which will undoubtedly increase the utilization of equipment.
Third, increasing environmental protection requirements

For the sake of the sustainable development of human society and economy, the world public has put more and more strict requirements on environmental protection. Whether the construction machinery has good environmental performance will become one of the important indexes for participating in the international market competition. Nowadays, many industrial developed countries, “Market Access Card.” Therefore, all countries in the United States, Europe, Japan actually developed engineering machinery that is “friendly to both people and the environment.”
Fourth, to speed up the upgrading

With the development of modern technology, the technology development and innovation of the world’s construction machinery products have been accelerated and the cycles of replacement have been shortened. The product families have been broadened and the product series become more sophisticated. The major US, European and Japanese companies have introduced the cameras The second generation, the third generation until the fifth generation of new construction machinery products.
Fifth, small and large size with the development

Large and medium-sized construction machinery is still the mainstream of construction machinery in the world, with annual sales of about 70 billion U.S. dollars. However, the tendency of construction machinery to extend toward both ends of miniaturization and large-scale construction is obvious. The United States, Europe, and Japan are the major consumer markets for construction machinery. As their large-scale infrastructure construction projects have been declining while those for repairing, protecting and urban small-scale projects are on the increase, in order to save labor and labor costs and increase work efficiency, various small, Micro-engineering machinery have come out. This machinery and equipment can be used for construction work in narrow areas or in residential homes and small-scale construction projects.

Sixth, the concept of industrial design throughout the product design

Industrial design is the product of the design, also known as the product’s artistic style. Construction machinery design can make the shape of the machine and its structure, function and use requirements of unity, and with people’s physical and mental coordination. This design should include the appropriate proportion of the ministries, body shape, color coordination, beautiful appearance of the instrument layout, as well as easy to operate intuitive and eye-catching trademark symbols. At present, the world’s major companies attach great importance to the industrial design of products that led to the emergence of a special research and design agency.

Seventh, robots to help create construction machinery

Ergonomic principles have been valued Since the 1980s, many of the world’s largest construction machinery manufacturing companies have invested a lot of manpower and funds to research and application of modern design methodologies Ergonomics Advocate people-oriented design ideas, pay attention to the machine Coordination with people. The application of electronic technology in construction machinery greatly simplifies the driver’s operating procedures and improves the technical performance of the machine. The use of electronic control can automatically select the machine mode of operation; the use of electronic monitoring can promptly detect and eliminate the failure of the machine system; the use of electronic sensors by microcomputer processing can automatically detect the quality of the machine.

Robots play a “catalyst” role in the transition of emerging and traditional industries. In the construction machinery industry, robots often perform spot welding, arc welding, painting and assembly on the production line. This not only ensures the stability of product quality and improves the efficiency of labor productivity, but also improves the working conditions and labor intensity of workers. In recent years, China’s construction machinery industry usher in rapid development, the urgent need to upgrade and restructuring, enterprises want to grab more competition in the market share and get rid of homogenization of the product competition, we must strengthen the level of automation of the production line, vigorously introduce the robot will not Or missing.

In addition, the performance and price of construction machinery products depend greatly on these spare parts, such as transmission parts, control components, diesel engines and key hydraulic components such as high-tech, high value-added core components, and in our country these projects Mechanical core parts mainly rely on imports, a serious constraint on the situation of China’s construction machinery enterprises to further develop and grow. Because foreign companies that control the core spare parts usually take the form of starvation sales, only a certain number of accessory products are produced each year, so as to achieve the purpose of guaranteeing price control. As an emerging industry that is nurturing and growing, there are still outstanding problems in the intelligent manufacturing equipment industry in our country. The main problems are as follows: weak technological innovation ability, limited core technologies such as new sensing and advanced control, small industrial scale, small industrial organization, , Weak and lack of internationally competitive backbone enterprises; industrial base is weak, high-grade and specialty sensors, intelligent instrumentation, automatic control systems, high-end CNC system, the robot market share of less than 5%.
Eighth, operating principle breakthrough

Operating principles of innovation and breakthroughs, working principle of construction machinery, including earthwork cutting, crushing, backfilling, geotextile screening, mixing and heating, paving the mixture, leveling, and compaction. The theory of these operations was originally based on bionics and Newtonian mechanics, while the development of shock science laid the foundation for the new operating principle of construction machinery. For example, the application of mechanical vibration, pulse, jet, photoelectric effect, and thermophysics has created the conditions for the construction machinery to save resources, improve the project quality, improve the production efficiency, work reliability, driving comfort and automation.

Ninth, hydraulic transmission

In the 1960s began to be applied to the roller, only 10 years time has been promoted and popularized. The existing road roller walking, vibration, steering machine brake and other systems have achieved full hydraulic transmission. Hydraulic transmission greatly simplifies the design of the roller drive and control system, hydraulic transmission smooth and easy operation, easy to implement stepless speed control and automatic control, to improve the overall roller production efficiency and compaction quality.

Tenth, one of the telecommunications and intelligent process

Modern engineering machinery should give humanity and spirituality. Spiritual construction machinery is an integrated system of mechano-telecom transmission with thought and mind sensing organs, neural networks, internal organs and hand, foot and skeleton. Electronic technology and sensors and mechanical devices combined to achieve automatic monitoring of construction machinery and automatic control, that is, the integration of telecommunications. The electronic sensor is one of the sensors of the machine and the organ of the machine. It is the medium between the machine and its work object. The electronic technology which is the core of the computer is the brain and central nervous system integrated with the machine and telecommunications. It accepts all kinds of information sent by the sensor, After processing the execution part of the machine instructions.
