Overhead Bridge Crane Oil spill three common reasons:
1. Manufacturers design unreasonable, such as no special ventilation holes, ventilation holes size too samll and other small design flaws. it will cause internal and external pressure is not balanced, resulting in the oil lubricants leakage. it also may be caused by connection surface seal is lax during long-term usage in the process.
2. The limit of crane processing technology grade, resulting in housing connection surface precision is not enough, sealing performance is lax, cause oil leakage.
3. The overhead crane crane operator personnel improper maintenance, lead to internal blockage, will result in connection surface seal is lax. while too much oil, fasteners not tightened and so on.
In order to prevent oil leakage, overhead bridge crane manufacturers will enhance the level of technology and design, such as add air breather on oil filling cover, improve precision of the process between connection surface. in daily usage, must do maintenance work regular, especially the venthole, fuel, housing, fasteners, etc, make sure all of them is in the normal state.
