Gear oil change so much easier to use electric hoist

Electric hoist with its own quality of life is a long and maintenance work is closely related to the use of electric  lift hoist  in order to maximize the role of equipment, improve work efficiency, without compromising the device itself, a very important point is the "lubrication" For the electric hoist gear oil use, the use of two weeks or so, need to be replaced, so not only can protect the electric hoist runs smoothly and quickly, while maintaining the lubrication of gears, so much easier to use electric hoist.
Electric hoist gear box oil operations from the beginning, probably about two weeks to check engine oil level is adequate.Hoist equipment Please visit the factory high dust oil, and periodically clear chains and limit foreign body within the guide groove group, to ensure the smooth operation of the chain. Long-term use of electric hoist, rust treatment should be done and the cleaning and maintenance, and run up and down minutes in order to maintain its performance. Foundry chain, can not be on the oil, because of dust on the chain for wear resistance. Crane from the (system) move, plus (minus) the slow speed required, regularly check the oil after the first three months of the case, less need to refuel.
Electric  rope hoist  parts keep drying operation is complete leaving Hua hoist when wet areas set, high temperature or chemical zone to maintain its performance. Chain maintenance, lubrication oil on the chain please.

Electric hoist uncoupling uninstalled pay attention to what?

Electric hoist lifting heavy process requires manual control and manipulation, which is a high demand for its safe use,  rope hoist  used on the preparatory work before and during use precautions, articles we have done previously introduced today, we explain the final step in the process of lifting heavy objects, electric hoist uncoupling uninstalled pay attention to what?

Wire rope hoist lifting heavy transportation in place, you should select the check good placement, electrical wiring and uninstall do not squeeze other pipelines, do not block the passage; different weights for different types of measures to be taken to assist the support, wedged, pad steady, classified display, you can not mix code, squeeze each other, but can not place vacant, has prevented a heavy rolling, side down, collapsed stack; operating personnel conducting  lift hoist  hook sling hook remover should be completely relaxed after all other then make sure that all removed from the hook spreader resurgence hook, remember not shaking rope hook cord, but does not allow the use of electric hoist pump cable.

Cleaning chain hoists should pay attention to what?

After a long period of use  Chain Block ,  unavoidable will accumulate a lot of dust, no time cleaning chain hoists will affect the use of equipment and life, but as a lifting device, it has a lot of cleaning work areas requiring attention, treatment is not good will appear rust, etc., the following cleaning  manual hoist  to introduce you to pay attention to what?

Chain hoists, especially inside the device is easy to fall into the dust, if not cleaned, it will affect the use of equipment, if you use water to wash, rinse improper chain hoists will rust, but do not rinse with water and dirt can not completely get rid of dust and dirt, in fact, the solution is simple,

Just use Chit machine and other auxiliary to complete the cleaning job you can, while you can use Blaster facing the chain  lift hoist  to handle internal dust Blaster larger the wind, can effectively flush out the dust inside, but some grease or other can be washed with water, and then use Blaster completely dry.

Individual characteristics of group hanging electric hoist

Group is a ring hanging electric  Wire rope hoist ,  the speed of a minimum due to run smoothly, it is used for more than one body together with lifting large irrigation work, today to introduce you to the individual group hanging electric hoist the main features.

Single-phase group hanging electric rope hoist  motor regardless of the primary and secondary windings, add a small lane on the line are their own reform. If the words of two, regardless of the primary and secondary windings of the line and end line of resistance is common as large, if the words of the primary and secondary windings of the primary winding and the common terminal must be greater than the secondary winding resistance and public really a resistor.
With a multimeter side look.Hoist equipment From the motor came out three lines, one is really a common line, the other two are the two windings into the line. It also can be seen coming out from the motor to determine the root of the number line, and if the secondary winding of the main requirements for reversing the words came out of the line from the motor root of the number is at least 4. If it is three and that is regardless of the primary and secondary windings of the motor where you look out from the root of the number line.
Single group hanging electric  lift hoist  lifting height H, is the top surface of the orbit, from the extract device promised to track down on the ground or below the top surface, called the decline in its decentralized depth interval, when used shall not exceed the lifting height, otherwise occur due to overloading caused by heavy falls and other accidents.
