Reasons for price fluctuation of vacuum stone lifter

Reasons for price fluctuation of vacuum stone lifter
 The price of vacuum stone lifter often fluctuates, so what determines the price of vacuum stone lifter?           
 1.  Steel price           
 This is the main factor, steel is the weight of the line crane, its price directly determines the final price of the equipment after shaping. From several tons to dozens of tons, there will be a large drop naturally. Therefore, the  fluctuation of steel price will naturally lead to the change of quotation. This customer should understand.           
 2.  Accessory factors           
 Some accessories will also rise in price, parts become more and more solid, performance improvement, will inevitably lead to price increases, these will also be calculated to the final cost price.           
 3.  Transportation costs           
 Because of the increase of transportation distance and oil price, it will lead to the increase of transportation cost, which indirectly stimulates the rise of the price of vacuum stone lifter.           
 4.  Human cost           
 Whether it is production, installation, or designers, these human costs will rise every year, which will inevitably lead to the final contract price increase.
 If the bearing on the crane is rusted, smear anti rust oil will be used. Soaking, brush and spray methods are commonly used.           
 Before applying rust-proof oil, the bearing surface must be cleaned. According to the nature of the surface of the rust-proof material and the environment at that time, the proper method should be chosen when cleaning.           
 The most commonly used methods are mechanical cleaning, chemical cleaning and solvent cleaning. After the surface is cleaned, it should be blown dry in the air or wiped with clean gauze. When the bearing is immersed, some small  articles should be immersed in the rust-proof grease, so that the surface of  the bearing can be adhered to a layer of rust-proof grease, so that the thickness of the oil film can be achieved by controlling the temperature or viscosity of the rust-proof grease.
 After the hoisting operation, the vacuum stone lifter need for simple and orderly arrangement, although simple but careful neat, in order to ensure that the next  use of the device is complete and undamaged!           
 1.  After homework. To check and investigate more frequently, we should investigate  whether the acceptance of special pressure gauges used to test pressure relief valves can exceed the set pressure. If we find that the number is abnormal, we must adjust the pressure relief valves in time.            

 2.  The operation handles used as hydraulic pressure in the line crane are usually placed in the position of the center of the body after the suspension of operation. Together, we should ensure the flexibility and reliability of the operation handles when they are applied.            

 3. It is necessary to hang the cable suspension on the inner line of the device in an orderly manner, and to bind the cable suspension in a robust manner. In the implementation of the whole operation, it is necessary to adhere to the same radian between all cable lines and hooks.            

 4.  Connecting the small screw and parts of each part of the crane, our operators should pay attention to checking whether it can be loosened at any time beside the usual operation of the crane. If there is loosening, we should immediately make relevant methods.
