How to remove the rust of the electric hoist, and how to prevent the electric hoist from rusting again? Our technology here also summarizes several methods to prevent the rust and rust removal of the electric hoist to share with you.
Because rust removal and anti-rust of electric hoist are common items of daily maintenance of electric hoist, the surface of gears in electric hoist gearbox should be coated with anti-rust grease containing barium petroleum sulfonate, and the rust condition and protection should be checked regularly.
If the electric hoist is rusted, it is necessary to scrape off the rust with hardwood chips or bamboo chips and apply oil again. If the original oil film has been damaged or deteriorated, it should be cleaned with no or gasoline first, and then painted with anti-rust grease.
The exposed surfaces and exposed threaded surfaces of the various parts of the electric hoist are prone to corrosion, so anti-rust grease should be applied to these parts.
The other is the steel wire rope. The steel wire rope should be coated with anti-rust lubricating oil, and it should be wrapped with sheet cloth or plastic film on the outside under non-working conditions. Calcium-based anti-rust grease should be injected into the bearing of the hook to prevent rust, and the anti-rust effect should be checked frequently to achieve the effect of extended use.
Overhead double-girder crane is an important tool and equipment for mechanization and automation of production process in modern industrial production and lifting and transportation. Therefore, double-girder bridge cranes are widely used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals and logistics turnover and other departments and places.
The double-girder overhead crane is hoisting equipment that is horizontally mounted over workshops, warehouses and stockyards for material hoisting. Because its two ends sit on tall concrete columns or metal supports, it is shaped like a bridge. As the name suggests, it consists of two main beams. The bridge frame of the double-girder bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is the most widely used and the largest number of hoisting machineries.
All electrical equipment enclosures of overhead cranes should be grounded. If the trolley track is not welded on the main beam, measures should be taken to weld the ground wire. The grounding wire can be galvanized flat iron with a cross-sectional area greater than 75mm2 or bare copper wire with a cross-sectional area of 10mm2 or galvanized round steel with a cross-sectional area greater than 30mm2. There should be more than two grounding positions for the driver’s cab or the crane body. The grounding resistance between any point on the crane and the neutral point of the power supply should be less than 4Ω.
As a large-scale machinery and equipment, in order to ensure the safe operation of the equipment during the operation, the grab crane equipment must be inspected and maintained after each operation.
There are many parts of grab bucket crane need to be inspected and maintained:
· Maintenance of motor and reducer. The motor and reducer have a great influence on the operating speed and efficiency of the crane.
· Maintain and inspect the motor casing, operating temperature, operating noise, vibration, etc., and solve the problems in time when problems are found and use them correctly.
·The daily maintenance of the reducer should be carried out in accordance with the operating instructions.
·The anchor bolts of the reducer should be checked frequently, and the connection must not be loose.
·For the lubrication of the walking device, the vent cap of the reducer must be opened for the first time to ensure excellent ventilation to relieve internal pressure.
·Before working, check whether the aspect ratio of the grease surface of the reducer exceeds the stipulation.
·If it is lower than the oil surface, increase the grease of the same model and specification immediately.
·During the assembly process, the bearing of each wheel of the traveling mechanism has been filled with enough grease, and there is no need to add oil every day.
·Grease can be replenished every two months through the oil injection hole or by opening the bearing cover.
·The grease can be disassembled, cleaned and replaced once a year. Lubricate the meshing part of each open gear once a week.
·For the maintenance and maintenance of the reducer, be sure to check the lubricating oil in the reducer to see if the lubricating oil level is within the specified range.
·When the oil level is lower than the specified oil level, add lubricating oil in time.
·When the grab crane is not used frequently and the sealing conditions and use environment are good, the lubricating oil in the gearbox should be replaced regularly.
·If the use environment is relatively bad, it needs to be replaced every quarter.
·If the water or oil in the oil tank deteriorates, please change the oil immediately.
·There are also relevant operating instructions when changing the oil, and the oil should be replaced correctly.
Grabs are generally used on cranes, mainly for loading and unloading of goods. If the maintenance of the grabs is not done well, long-term contact with external water and air will cause damage to the surface of the grabs, or even produce Some corrosion seriously affects the normal use of the grab. After using the grab bucket, the grab bucket should be stored properly to prevent improper storage from affecting the normal use of the grab bucket.
The lifting industry is developing with each passing day, and the technology is also becoming more and more advanced. Various small and light lifting equipment such as electric hoists, miniature electric hoists, chain hoists, etc. have emerged one after another, replacing various manual tools in the past, such as chain hoists, manual hoists, etc. Gourd etc. Therefore, some customers worry that the manual hoist will gradually become outdated with the development.
Although science and technology are developing rapidly, the chain is constantly improving and upgrading to adapt to the development of the times. In addition, due to space and power constraints, many electrical equipment cannot be used, so chain hoists are still a good choice. From another point of view, many chain hoists are constantly coming into our lives. On many occasions, when small objects and short distances need to be lifted, chain hoists are the most suitable. It is now not limited to lifting operations and industrial needs. It is also widely used in life and can be used in any corner of all walks of life.
The main application advantages of double girder overhead cranes in Philippines
With the development of society and economy, the application of double-girder overhead crane in our daily life is becoming more and more common. Whether it is in the wharf or the construction industry, these cranes or electric hoists are used more and more. Application, the effect is obvious, and the completed workload is also high, this is still very important, following the development of our market is getting faster and faster, these double-girder crane devices have improved a lot, from quality to workmanship quality, etc. In other respects, the application of these double-girder cranes is higher than usual. Therefore, double-girder cranes are more accepted in the Philippines market. Now let’s understand the application benefits of double-girder overhead cranes!
1. Good sealing performance of overhead crane. The chain guide part is a fully enclosed design to ensure a clean environment for the engagement of the chain and the chain guide seat.
2. Adopt reverse braking, improve braking performance, prolong brake service life, and can adapt to high temperature and high humidity pretreatment environment within a certain range. Suitable for climate conditions in the Philippines.
3. The brake clutch gearbox is maintenance-free for ten years, reducing maintenance frequency and maintenance cost.
4. Equipped with cylindrical asynchronous motor, high power and sufficient power reserve.
High continuity rate of power connection, adapt to the working conditions of frequent starting and braking; 5. Faster lifting speed and higher working level fully meet the requirements of production takt and production intensity.
6. All imported round steel chains of world-renowned brands are highly wear-resistant and anti-aging, with long service life and good wear resistance; and there are many types of double-girder cranes, which can also be produced and designed according to user needs, suitable for different occasions, convenient by users in Philippines.
Before using the double-girder overhead crane, a comprehensive inspection of the crane must be carried out, including understanding the structural characteristics of the European-style single-double-girder crane, the wear and tear of some commonly used parts of the crane, and the normal performance of these parts must be guaranteed; At the same time, check some lubricating oil, etc. If there is a shortage, make up for it in time, because once it is used up during the work, it will cause great harm to the crane and must be treated with caution; there are also some instrument panels to be checked, because once there is a problem, these instrument panels will give Our necessary information prompts help us solve problems in a timely manner and avoid greater losses, etc. These pre-work inspections are very important.
2. The use process must be strictly in accordance with the operating procedures
After all, it is a large and heavy machine, so its danger is there, which requires us to master the operation skills, and we must master the problem of using the crane, so that we can better play its performance, effectively serve our work and improve our work efficiency. Therefore, we must pay careful attention to the working conditions around the machinery in our work. In particular, it is strictly forbidden for people to move around, and we must observe them carefully; in addition, we must use a professional eye to visually observe the working conditions during the work process, especially some dangerous operations. This is true; when we lift heavy objects, we must keep them within a reasonable range, while ensuring the safety of people and buildings.
3. Occupational sensitivity is very important in the operation process
When we use the double-girder crane to work, we must seriously feel the normal operation of the machine. We can grasp the normal situation of the machine through the direct display of the instrument panel. If the instrument panel is not perfect, we can only pass More professional skills to find more problems, that is, to find out the characteristics of some problems through our eyes, and to listen to the changes of the sound with our ears, so as to find problems in the noise, and then timely and decisively It is necessary to take effective measures to solve these problems, so as to improve the working performance of double-girder cranes.
Double-girder cranes are more machines for hoisting heavy objects, so in many cases, it solves more labor costs for our lives, and at the same time effectively saves more capital investment of enterprises, but in the process of use We must pay attention to many problems, and the above items are some of them.
Only by effectively mastering the many precautions for the use of the crane can we effectively grasp its performance and let it play an important role in our life. Effectively While improving work efficiency, it can better play its advantages to meet the needs of our lives.
Recently, we received feedback from customers that due to the untimely maintenance of the machine, the reducer of the overhead crane had oil leakage. After receiving this feedback, we immediately kept in touch with the customer and inquired about the purchase time, type of bridge crane and usage frequency of the customer. After consulting the relevant engineers, we provided the customer with a series of after-sales services, and the customer was very satisfied with our service.
Overhead cranes are widely used in modern industry and play an irreplaceable role in the healthy development of enterprises. However, while overhead cranes bring high efficiency, convenience and speed in the production process of enterprises, due to the unsafe factors of machinery, frequent accidents will bring huge economic losses to enterprises. How to ensure the safe operation of overhead cranes is our top priority.
During the use of bridge cranes, the problem of oil leakage from the reducer is relatively common. The reducer with serious oil leakage will not only lose a lot of lubricating oil, but also have a bad impact on the cleaning and hygiene of the crane itself and the surrounding environment, and also affect the progress of the work. What is the reason for the oil leakage of the reducer? How should we prevent and how to deal with the reducer that has leaked oil to briefly summarize.
There are three main reasons for oil leakage of the reducer: First, due to unreasonable design, such as no ventilation holes or too small ventilation holes, the internal pressure of the reducer cannot be balanced with the external pressure, resulting in the leakage of lubricating oil; due to the deceleration of the trolley operating mechanism The oil pool of the device is composed of upper and lower boxes. Because of long-term operation, the connection surface of the two boxes is not tightly sealed and easy to leak oil. The second is that the manufacturing design fails to meet the requirements, and the accuracy of the joint surface of the box is not enough, which leads to the lack of tight sealing and oil leakage. Third, improper use and maintenance caused multiple blockages, resulting in too high internal pressure, too much oil, and too high oil level; loose connecting bolts made the joint surface of the two boxes not tight.
In order to prevent oil leakage of the reducer, the design should be improved, and a ventilation device should be installed on the observation hole cover and the oil filling hole cover of the reducer to ensure that the pressure inside and outside the box is balanced and air flow smoothly; Prevent the deformation of the box; in addition, do maintenance work, check and unclog the vent holes of the reducer frequently, the oil amount is appropriate, overhaul and repair the split surface of the box, and replace it if the deformation is serious; clean the oil return tank and fasten the bolts.
