Edit: vigorously lifting machinery Views: 33 Add Time :2013-11-18 08:11:44
   wire rope winch is the most common kind of crane flexible member, such as we use more rope around mini electric hoist, which due to the small volume, at home, hotels, shopping malls can be used, it is the use of wire rope for lifting lift heavy loads. Rope application so extensive, that it itself in the end what advantage is how widely?
   Rope hoist from their own conditions in terms of high strength, large carrying capacity, and flexibility, impact resistance, weight is small; at work, flexibility is good, smooth operation, low noise and high-speed operation, it is important not suddenly break.
   Although the rope so strong advantages, but also need to carefully after use maintenance to increase the efficiency of times.

Use explosion-proof chain hoists inspection before

1 explosion-proof  chain block   chain lubrication before using hook method to squeeze into the oil, oil-based lubricants name is calcium; biannual lubrication time.
2, the proof chain hoists lifting parts before checking intact, transmission parts and lifting chain oiled, idling normally.
3, lifting chain surface if worn, scratched traces strictly prohibited.
4, proof chain hoists lifting heavy objects when operating from the ground to try to check the work before it can continue normal operation lifting.
5, explosion-proof chain hoists rise and fall distance must not exceed the height marked to prevent damage to components.
6, Do not use non-manually driven  rope hoist  lifting heavy objects, if not pull movable weight situation, not afterburner.
7, proof chain hoists should check whether other heavy weights have been implicated, the weight is beyond the rated capacity, hoist parts for damage or other abnormal conditions.
8, the operator standing ban on the operation of  manual hoist  lifting weights, weight lifting may not be vacant after leaving the job site

Steel cord before using the hoist installation and commissioning

Electric wire rope hoist  before use in order to ensure safe use, customers also need to make simple commissioning work, the following details for you:
Electric wire rope hoist components are: motor, transmission, drum and rope four parts. The position of the motor and the roll can be divided into four types, different types have their advantages and disadvantages.
(A) motor axis is perpendicular to the axis of the hoist drum worm gear used, the width large size, structure is more cumbersome. This structure appears early in love, has no such type.
(2) The motor axis parallel to the roll axis, this structure is the biggest advantage of the electric hoist height and length dimensions. Disadvantage is the width dimension, manufacturing and assembly of complex, large orbital turning radius is large.
(3) motor mounted on the inside of the wire rope  manual hoist  drum hoist, the length dimension is small, relatively compact structure. But the motor heat is not good, if there are problems inspection, installation, maintenance, motor is not easy.
(4) motor mounted on the outside of the drum hoist, this way, to change the motor heat is not good for a big disadvantage, but also more convenient installation and maintenance easy. But the length of the large size, is not suitable for places where space is limited.
Electric wire rope hoist installation should pay attention to the following aspects:
Electric wire rope hoist mobile use of the track, I-beam by the user according to GB706-88 standard design of their own choice. Install a small car to be adjusted by adjusting the washer to ensure the orbital rim 3 ~ 5mm gap between the edge of the can.
Fixed hoist should be installed to ensure proper security methods, cage safe and reliable.

Buy electric hoist should be noted that six basic parameters

     The use of safety-critical electric lift hoist , electric hoist in addition to strictly consider buying gourd quality and after-sales service, but we need some basic knowledge of electric hoist is understood that in the time of purchase to facilitate our use of the environment according to their own choice suitable products, the following introduces you to buy electric hoist should be noted that six basic parameters:
1, Installation: hoist into electric trolley and fixed, fixed can be divided into fixed (A1) and lower fixed (A2), to choose according to the actual situation of the electric hoist installation.
2, I-beam hoist hook to the bottom center:chain block electric hoist purchase should pay attention to the spacing between the upper and lower hook, because in certain plant would hoist hook spacing specific requirements.
3, voltage: electric hoist Because in all walks inside, using the voltage is not the same, there are 380V 220V China industrial electricity consumption, and even 440V, 60HZ, 380V, 60HZ series of non-standard power supply.
4, motor power: Different electric hoist motors are not necessarily identical, the same 10t electric hoist motor is also possible that 13KW or 7.5KW.
5, the lifting speed: Average electric  rope hoist  lifting speed is divided into single-speed (8m/min) and dual-speed (8/0.8m/min) two kinds, generally no special requirements are often used in the case of single-speed electric hoist (ie CD1-type), if your condition requires heavy lifting required to pinpoint the course of the case, easy to use two-speed electric hoist (ie, MD1 model).
6, lifting height: electric hoist as a promotion tool, would lift height has strict requirements. So buy electric hoist, you should first select according to plant height of lifting height, the conventional lifting height has 6,9,12,18,24,30 m, special occasions, according to user requirements for non-standard design.

Use wire rope safety technology

        Wire rope safety technology involves the kind of manufacturing methods, constructors performance, force status, as well as maintenance, inspection, scrap, and many other issues, is a relatively strong professional technology, each security managers and technical personnel should be rope on the knowledge of the situation by force and have a basic understanding of operating status.
        Wire rope electric  rope hoist  is a high usage of components, one of which is due to its unique characteristics of the decision. Compared with the rigid member rope, wire rope with high strength, light weight, good flexibility, impact resistance and other characteristics, particularly outstanding is its safety and reliability.
        In normal use of electric hoist rope generally does not occur suddenly breaking even destruction is also a precursor,wire rope hoist generally always individual, locally broken wire, gradually developed into the whole rope, there is a period of time to process, if rope suddenly broken, because the load exceeds its limit breaking force occurs suddenly destroyed entire rope. This provides such a possibility, as long as usual to strengthen the hoist rope safe management and use, accidents caused by the rope can be avoided. But the rope electric hoist force status changing, complex work environment, and its destruction in addition to mechanical damage, the structure of improper selection,hoist equipment improper maintenance checks, wire rope failure promptly discarded and no other reasons for updates.

Electric chain hoist crane group how to use

Replace with electric  Hoist equipment  lifting groups in the new tank construction, construction can greatly reduce the labor intensity and improve working efficiency. However, the construction of the tank lifting how to avoid overloading group hanging electric hoist operation is to improve the efficiency and safety of the key, but also need to attach great importance to the construction team for each question.
First, the overall weight of the tank should have a correct calculation, generally selected from the  rope hoist  that the total weight of the overall weight of the tank more than 1.5 times. After determining the number of units of electric hoist, to accurately calculate and determine the spacing of hanging points, each lifting point spacing must be equal and balanced distribution. Requirements for the first time since the construction process less open sunroof, first hanging point to as little as possible, consistent spacing lifting point, consider hanging point equalizer setting to keep the spacing of hanging points equal as possible for both electric hoist load operation to create the conditions. Based on past experience in construction, for the first time hanging point is generally selected  lever hoist  half the number of units, the second hoisting construction has been completed, that is, in a timely manner before the third layer lifting up into the rest of all lifting points uprights, hang entire electric hoist, all put into the third layer lifting operation. In improving operations, by experienced professional rigger scene commander.

Haze environment uses electric hoist crane group should pay attention to what?

Group hanging electric Rope hoist  operation in normal environmental precautions have previously told you about before. But the group hanging electric hoist operation in environments haze win should pay attention to what? These details for you:
Typically, the group hanging electric  lift hoist  is not allowed to work in the fog and haze, but some engineering work to be completed ahead of schedule, and sometimes can not be delayed, and therefore must also be foggy day job. Electric chain hoist can be further fog job, but be careful with the job, fog visibility range is small, and sometimes electric hoist lifting too high, below the hoist operator can not see the location, this time you need the job to the top set striking lights can also be carried out employing the above command operation, you can make use of radio and other equipment. In foggy weather operations, should do a good job in the electric  wire rope hoist  fog water surface preparation can be evenly with oily surface of the material, especially the chain. Finished using electric chain hoist immediately after drying internal parts to prevent rusting internal parts, you can use tools such as Blaster dry. After drying, were stored in a dry environment.
Must not be ignored for the group hanging electric hoist after use without maintenance, which will lead to hoist rust corrosion, affecting life.

How to properly clean electric hoist crane group

This time in electric  Hoist equipment  electric hoist crane group every crevice drops of oil in progress, to be fully saturated, the available chopsticks wrapped in a thin object to force the dirt and other dirty rag to pull away, then rinse with water, ask the customer must pay attention to the water after cleaning group hanging electric  rope hoist   be sure to dry in time, and, in not dry before lifting operations can not be done, during cleaning, you should avoid group hanging electric hoist motor inlet.

Stage gourd gourds and mini distinction

Stage gourd gourds belong to small and micro-electric  hoist equipment , both can be used in stores, supermarkets and other fields, but in terms of structure or principle are very different, the following details:
Stage electric hoist chain hoist is, in strict accordance with touring exhibitions to design, the main role is to stage equipment lifting. This stage hoist black paint on the surface after the treatment, easy to install them, compact shape, one can also be hung upside down to use, especially for transporting small weight, limit switch device can  lift hoist  motor is automatically stopped, preventing the chain exceeded. Ensure that the stage hoist at work runtime security.
The miniature electric hoist wire rope hoist is a kind of divided into two kinds of household and industrial miniature. Its lifting speed can reach 10 m / min, rope length at the beginning designed to 12M, but also can be lengthened can be customized, hook side hook specially designed with advanced settings, increasing the weight lifting equipment, but it should be noted that non-used upside down, thanks to the public electricity 220V mini electric  rope hoist  is mainly used in such everyday civil, industrial production line, especially for high-rise buildings to lift heavy items from downstairs.

How to better improve the efficient use of electric hoist safety

Electric  Wire rope hoist  is a small light lifting equipment, small size, light weight, simple operation, easy to use features, for the industrial and mining enterprises, storage terminals and other places. So in practice how to better reduce risk and improve safety index? Now the security methods used to teach to everyone.
First, installation and maintenance, must strictly limit device is flexible and reliable inspection, when the hook up to the upper limit position, the hook to the roll shell casings interval must be greater than 50mm.
Second, in use, the absolute prohibition in circumstances not permitted, or exceed the rated load and nominal hourly closing times circumstances.
Third, the new installation or after installation by dismantling the hoist should first be empty commissioning times. But not before the installation is complete, avoid power test rpm.
Fourth, in normal use static load test should be carried out before, and check whether it is normal.
Fifth, to adjust the amount of electric  lift hoist  brake down, they should ensure that the rated load, the amount of braking down.
Sixth, after the work is required to supply the total gate opened to intercept the power.
Seventh, do not allow press both the  rope hoist  movement in the opposite direction of the flashlight door button. (10t, 16t, 20t must be greater than 120mm). When the hook down to the lower limit position, should ensure safety rope on the drum circle, circle must be effective and safe in two laps or more.

How upside down stage hoist installation?

Stage upside down electric Wire rope hoist  is a relatively strong professional lifting equipment, it is mainly due to the arena touring, touring exhibition design requirements. Stage electric hoist factory have been tested 3 times and 2 times overload test, described in detail the stage today for your initial use of electric hoist upside down how to install a hybrid commissioning?
Stage upside  rope hoist  initial lubrication is required before use, a, will need to be lubricated chain degrees, including a chain, the contact point between the connecting rod must be properly lubricated. b, gearbox: the ambient temperature is about -10 ℃ to 50 ℃ between, you should use 220mm2 / S 40 ℃ temperature and high pressure gear oils with additives, gear oil specifications for DIN 51502 CLP 220.
Lubrication work is completed around the object to be cleaned, the stage upside down hanging electric hoist will need to be a place without hindrance. Suspension point is a location that allows carrying hooks and any anticipated load increase and decrease the unimpeded. Bottom lumps must not touch the ground, if there is a need, in the end of the chain slack adjustment CHAIN ​​stop position.
Connected to the power supply with the stage hoist operation voltage and frequency are marked on the motor nameplate rated voltage on in connection stage before powering electric  lever hoist  definitely want to check these figures consistent with those of the supply voltage.
Finally, you need to debug the stage hoist, after completing the assembly, but the crane being used in normal operation, the following procedure should be completed. Isolated power supply, check all mechanical and electrical connections and connections are locked and is secure. Turn on the power to all the stage lightweight load operation range of electric chain hoist and check operation is always smooth. In the light-weight bearing and full load conditions, check the operating status of the stage hoist.
