HOW TO MAINTAIN HOISTING MACHINERY IN WINTER?
Lifting machinery is commonly used in construction site lifting equipment, used for lifting construction raw materials.In order to ensure the safe operation of the crane, the daily maintenance of the crane is particularly important, especially the winter is coming, the use of lifting machinery in winter is different from other seasons, there are many special precautions.
As we all know, the use of crane electric hoist has environmental requirements, such as not working in a wet environment.But in some special cases, it is necessary to make the electric hoist work in a humid environment.At the moment, we must do a good job in the maintenance of electric hoist.How can we prevent these defects?
The lubricating oil of the gear box of hoisting machinery must be replaced with antifreeze lubricating oil as required;Pay attention to fire prevention when heating the crane driver's cab;The connecting bolts of the main components are not loose;The wear condition of hoisting machinery wire rope and the threading and winding of pulleys meet the standard requirements;No damage to the power cord;The verticality error of hoisting machinery should meet the standard requirements;
Cut crane electric hoist use time.Do not operate the equipment in a wet environment for a long time to cut down the water on the equipment for a long time to prevent the corrosion of the crane electric hoist.
Snow should be removed in time during and after the snow, and adopt anti-skid measures;In case of wind speed of 12 m/s strong wind or heavy rain, snow, fog and other bad weather, lifting machinery should be suspended;
Maintain crane electric hoist.If you must use electric hoist in wet environment, you must maintain the product, remove moisture in time, and do a good job of lubrication of the product, in order to reduce the corrosion of the product, to achieve the desired repair role.
Lifting machinery anti-falling safety equipment can only be used in the calibration period;The main components of hoisting machinery and safety equipment should be checked regularly, at least once a month, and make records.If there is any abnormality, it should be repaired in time and pay attention to repair.
Do a good job in the maintenance of electric hoist.If the humidity is relatively low, blow dry the hoist of the crane with the fan.If the wet area is large, it is necessary to maintain the electric hoist to reduce the risk of damage.
The above is the protection method of hoisting electric hoist in wet environment.Of course, this is only about the specific operating environment.In general, our daily operating environment requires that the electric hoist should not be in a wet environment.
