集装箱码头场桥轮胎式龙门起重机驱动链条润滑改良，优润(u.lube)团队现场服务
drive chain lubrication improvementsolution for rubber-tired transtainer on container terminal yard
场桥大车不但要承受场桥的重量，而且易受海水的侵蚀，甚至会承受冲击载荷。大车润滑一般采用强制润滑，对润滑油的抗磨抗水冲能力性能要求比较高。
the rtg truck not only bear the weight of rtg, and is easy eroded by seawater and even bear the impact load. the truck lubrication generally adopts forced lubrication, and the performance requirement of anti-wear and anti-water erosion ability of lubricant is relatively high.
目前某集装箱码头对龙门吊行走驱动链条使用了某牌普通锂基脂进行润滑，效果不理想，出现些问题。
at present, a container terminal uses a brand of ordinary lithium grease to lubricate the gantry crane walking drive chain, the effect is not satisfactory and some problems appear.
普通锂基脂其抗负载能力不够强，抗海水及海边盐环境能力比较差，工作温度，尤其是低温性能差一些，并且氧化安定性不够强，在海边的环境是很容易润滑失效。
the ordinary lithium grease is not strong enough to resist the load, the seawater and salt environment, the working temperature, especially the low temperature performance, and the oxidation stability is not strong enough, so it is easy to fail to lubricate in the seaside environment.
目前该码头使用的锂基脂渗透性能不足，无法渗透到链条销轴;而且油膜强度不足，抗磨性能较差。容易造成销轴端部磨损，进而断裂。另外锂基脂对码头存在的潮湿/腐蚀性环境防护性较差，容易造成链条锈蚀。下图为该码头行走链条，链条形成大量油泥，齿轮与链板内侧有磨损现象。
the lithium grease currently used in this terminal has insufficient penetration performance and cannot penetrate into the chain pin; moreover, the oil film strength is insufficient and the anti-wear performance is poor. it is easy to cause the pin end to wear and break. in addition, the lithium grease has poor protection against the wet/corrosive environment in the terminal, which may cause the chain to rust. the picture below shows the walking chain of the terminal, a lot of oil sludge is formed on the chain, and there is wear on the inside of the gear and chain plate.
对于龙门吊行走驱动链条润滑改良，优润(u.lube)团队建议使用性能好的链条油，如优润(u.lube)的magn wr100高粘附链条油，具有良好的粘附性，能够在接触表面形成非常强韧的润滑油膜，起到良好的防锈、抗磨作用。与传统链条油相比，产品不飞溅、不滴落，并且具有良好的排水能力，链条油渗透性强，可以有效润滑链条运动部件细微部位，保障驱动链条长时间运转，减少维修保养工作。
for rtg drive chain lubrication improvement, u.lube team recommends using chain oil with good performance, such as u.lube's magn wr100 high adhesion chain oil, which has good adhesion and can form a very strong lubricating oil film on the contact surface, playing a good anti-rust and anti-wear role. compared with traditional chain oil, the product does not splash and drip, and has good drainage ability. the chain oil has strong penetration, which can effectively lubricate the fine parts of the chain moving parts, guarantee the long operation of the drive chain, and reduce the maintenance work.
