First of all to always check the motor shell and bearing parts of the temperature, the motor noise, vibration, whether the abnormal phenomenon. In the case of frequent start-up, due to low speed caused by reduced ventilation cooling capacity, and the current is large, the motor temperature rise will soon increase, it should be noted that the motor temperature rise shall not exceed the upper limit of its specification. Adjust the brakes as required by the motor instructions. The daily maintenance of the reducer can be found in the manufacturer's instruction manual. And should always check the reducer of the anchor bolts, the connection shall not be loose.
2, the lubrication of the walking device
Second, the crane parts maintenance technology to remember a good fan lubrication, such as the use of the reducer should first open the ventilation cap to ensure good ventilation to reduce the internal pressure. Before work should check the reducer lubricating oil surface height to meet the requirements, if less than normal oil, should be promptly increase the same type of lubricants.
The wheels of the travel mechanism are filled with enough grease (calcium-based grease) at the time of assembly without the need for daily refueling, every two months through the oil filler hole or open the bearing cap, add a grease every year Remove, clean and replace grease once.
