as a matter of fact, the service life of the bridge crane is related to many factors, and the standardization and maintenance of the overhead crane have a very important influence on the service life of the double beam crane. Therefore, the customer must pay attention to it.

In the process of use, bridge cranes should be carried out according to the corresponding operating specifications and requirements, and comply with the corresponding safety standards. In the process of using the whole bridge crane, they can not operate at will and do not operate violating. For example, the requirements on the load and the use requirements under different environment are different.

in addition, it is important to think of the use of bridge cranes for longer and necessary maintenance, because the performance and quality of the cranes are usually affected by a certain time, which requires us to maintain a reasonable maintenance of the whole machine, to carry out good nursing from its basic surface and internal structure, to ensure the weight of the bridge type. The machine can be well maintained after different operations.

For customers, the longer the use of overhead cranes, the lower the overall cost, which can effectively save user costs.

LED Design for Overhead Crane

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 a 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 seeing the lifting of the goods. vision.

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 have 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, Ellsen 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, Ellsen 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 Ellsen CXT crane’s remote control and communicator use the same plug, so the upgrade plan is very simple. Ellsen 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

Bridge Crane Maintenance

How to prevent the double beam crane with variable frequency speed regulation stopping failure in summer?

The working environment of the crane is abominable, and most of it works in the environment of high temperature, high dust, and even in the environment containing harmful gases.According to the actual working environment, such as the metallurgical crane electric room need to take heat insulation and dust to increase the cooling air cooler and other cooling measures.
Frequency converter general installation environment requirements: minimum ambient temperature -10 C, the highest environmental temperature of 40 degrees.Studies have shown that the failure rate of the transducer increases exponentially with the increase of temperature, and the service life decreases exponentially with the increase of temperature. The life of the converter will be reduced by half if the ambient temperature is increased by 10 degrees.Summer is the frequent season of frequency converter failure, to ensure the long-term stability and reliable operation of the frequency converter, the key is to the daily maintenance.

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.
