Ensure the crane did not forget to check the safety of electrical equipment grounding line hanging before using six tons of line hanging, we are accustomed to submit a report on the contents of the crane electrical equipment grounding check, which will help us to go by the book, you can ensure that the line hanging Safe and Secure! 1. Check with integral metal structure to do when the grounding line 9 tons of line hanging, connecting metal structure with a non-welding, whether to use a separate ground lines or jumper treatment; 2. Check that all electrical equipment Lifting normally energized between the metal housing, the transformer core and the metal barrier, threading metal ducts, cables and other metal sheath and the metal structure is a reliable ground connections. The key part of the reason Cranes single-beam crane line reducer crane single girder crane line reducer oil spill, there will be some failures after prolonged use, such as oil. After the crane reducer, cause a decline in the efficiency of the device, in order to solve the problem, we want to know what causes crane reducer, the following will explain to you the proof crane manufacturer, I hope to help you: 1. Because of the design does not reasonable, such as design no holes or air hole is too small, so that the internal pressure and external pressure imbalance, resulting in oil spills; because the car is running mechanism gear oil pool is the case of the upper and lower, because the long-running, two boxes sealed Easy spill lax joints. 2. mainly the description, the bonding surface accuracy is not because Mifengbuyan and oil spills. 3. Protection of improper use of a plurality of closed seven tons of line hanging, LED internal pressure is too high, too much oil, the oil level is too high; connecting bolts loose, not tight surface of the two boxes. 10 tons of line hanging | generous heavy (certified) | Panzhihua line hanging by heavy machinery Co., Ltd., Henan Province, generous.
