In order to ensure the safety of cranes, we must be familiar with the causes of various failures of cranes and the ways to remove them.

1, in order to extend the service life of crane electrical equipment, electrical equipment should be kept clean, such as resistors, control panels, contactors and so on. Eliminate dust, dirt and attachments inside and outside, to prevent leakage, breakdown, short circuit and other phenomena.

2, often observe motor rotor sliding line brush contact is bad, whether wear and so on.

3, whether the sound produced by motors, brakes, relays and so on is normal.

4, check the cam controller and contactor contact whether there is a singeing phenomenon, if there should be timely replacement or use abrasive cloth after grinding.

5, when conditions are bad, motor, wire and insulation resistance should be measured regularly. Attention should be paid to the insulation cycle of conductive slide wire support and grounding of various equipment housings. 6. The rust and dirt on the slide rail must be cleaned at any time and keep the conductive parts in good contact.

7, whether the installation of electrical equipment is solid, whether there is loosening phenomenon, whether the rotation of the active parts is flexible, and properly lubricated (contactor magnetic loss surface is not Planck radiation formula decontamination).  

We find that in most cases, equipment users always seek emergency maintenance when equipment fails or even paralyzed, resulting in huge downtime costs and even serious impact on production and delivery time. It is against this phenomenon that we have launched a new "worry free plan" to help customers regularly maintain equipment, reduce the time between failures and reduce maintenance times, thereby reducing operating costs and prolonging the service life of cranes. Customers can choose flexibly according to specific circumstances.

Customers can also set up their own maintenance plan according to their own different needs. They can also request our service engineers to enter your factory, so that customers can avoid hiring their crane maintenance engineers, and avoid the trouble of personnel management and equipment maintenance management.

According to the different needs and applications of customers, we have developed 3 kinds of worry free schemes, including Golden Shield, silver shield and copper shield.
1, Golden Shield worry free program
It includes the whole year maintenance project (4 comprehensive maintenance +4 routine maintenance), completed by our professional technical and service personnel. Fixed annual maintenance cost and preventive maintenance plan will solve your maintenance cost and maintenance plan. In addition, you will also enjoy manual labor and special discount for accessories and free emergency call repair service.

 
2, silver shield worry free program
The crane contains two times a year for comprehensive maintenance and two routine maintenance. Through a series of inspections and commissioning work, your crane can run well. Under such circumstances, customers can also arrange their own weekly, monthly and quarterly maintenance items. At the same time, we have prepared a corresponding discount for clients of the silver shield worry free program.


3, copper shield worry free program
It is a flexible and customizable plan to help you better finish the maintenance of cranes. You will have the opportunity to get a free routine inspection provided by professional technicians, and we will submit a detailed inspection report to provide professional advice to ensure that the crane is in good working condition. According to our suggestion, you may choose to complete the maintenance work by yourself or by our technical personnel.
