单梁起重机保都有规定的额定寿命,但这些其实都只能作为一个参考数据,如果日常生活中你多加用心呵护的话,单梁起重机保的性能将会超出规定的使用寿命。

Single beam cranes have a specified rating life, but these can only be used as a reference data. If you care more in your daily life, the performance of the single beam crane will exceed the specified service life.


但是如果日常生活中你往往对单梁起重机保的维护保养和操作较为疏忽的话,那么单梁起重机保将有可能提前衰老。

However, if you are often negligent in the maintenance and operation of the single beam crane in daily life, then the single beam crane will likely age in advance.


电动葫芦小车间隙是否在正常范围内?日常单梁起重机检查中经常发现有些葫芦小车与主梁工字钢的间隙明显过大。

Is the electric hoist trolley gap within the normal range? In the daily single-beam crane inspection, it is often found that the gap between some hoist trolleys and the main beam I-beam is obviously too large.


由于葫芦是靠小车挂在工字钢上的,如果间隙大于工字钢面宽就有可能挂不住。导致整个葫芦坠落,后果可想而知。

Since the hoist is hung on the I-beam by the trolley, if the gap is larger than the width of the I-beam, it may not be able to hang. The result is that the whole gourd falls, and the consequences can be imagined.


单梁起重机电机固定是否牢固,电机坠落的案例也很多,只是正好砸中人员的情况不多。因为电机(大车电机)一般在靠边的位置。

Whether the single-girder crane motor is fixed firmly or not, there are many cases in which the motor falls, but there are not many cases in which the personnel are in the middle. Because the motor (large motor) is generally in the position of the edge.


坠落原因主要是单梁行车操作过程中的振动导致固定止松动引发。力福汀起重机的解决方式值得我们去借鉴:在电机上加装防坠锁,在电机坠落时可以拉住不至落地。

The reason for the fall is mainly caused by the vibration during the single beam driving operation, which leads to the fixed looseness. The solution of the Lifuting crane is worth learning. It is equipped with an anti-drop lock on the motor, which can be pulled and not dropped when the motor falls.


欧式起重机标配都是变速运行,这种情况下起重设备运行非常平稳,几乎没有振动。

European cranes come standard with variable speed operation. In this case, the lifting equipment runs very smoothly and there is almost no vibration.


主梁与端梁连接螺丝有无松动,造成这个隐患的主要原因也是振动,因此建议使用尽量选用变速起重机,相比单梁起重机安全、稳定、低故障率。

Whether the main beam and the end beam connection screws are loose, the main cause of this hidden danger is vibration. Therefore, it is recommended to use the variable speed crane as much as possible, which is safer, more stable and has a lower failure rate than the single beam crane.

单梁起重机如何保养维护

How to maintain and maintain a single beam crane

1、经常检查单梁起重机电动机外壳以及轴承部位的温度、电动机的噪音、振动有无异常现象。

1. Always check the temperature of the motor housing and the bearing parts of the single-girder crane, and whether the noise and vibration of the motor are abnormal.


2、单梁起重机在频繁启动情况下,由于转速低引起通风冷却能力的降低,而且电流较大,电机温升会很快的提高,应当要注意电机温升不能超过其说明书上规定的上限值,按照电动机使用说明书的要求调整制动器。

2. In the case of frequent start of single-girder crane, the cooling capacity of the ventilation is reduced due to the low speed, and the current is large, the temperature rise of the motor will increase rapidly. It should be noted that the temperature rise of the motor cannot exceed the upper limit specified in the specification. Value, adjust the brake according to the requirements of the motor instruction manual.


3、在单梁起重机使用不是很频繁且又密封状况和使用环境良好的情况下,单梁起重机减速箱内的润滑油每半年需要更换一次,单梁起重机在使用环境恶劣的情况下,每个季度需要更换一次。

3. In the case that the single-girder crane is not used very frequently and the sealing condition and the use environment are good, the lubricating oil in the single-girder crane reduction gear needs to be replaced once every six months, and the single-girder crane is used in the harsh environment. Need to be replaced once in the quarter.

发现箱内进水或是油面始终有泡沫并且确定油已经变质的时候,必须立即换油,换油时应严格按照减速箱使用说明书规定的油品进行更换,一定要避免油品混合使用。

If you find that there is water in the tank or there is foam on the oil surface and you have determined that the oil has deteriorated, you must change the oil immediately. When changing the oil, you should replace it with the oil specified in the instruction manual of the gearbox. Be sure to avoid mixing the oil.


4、减速机的日常维护可以参考单梁起重机生产厂家的使用说明书来进行维护,并且要经常检查减速机的地脚螺栓,连接不可松动。

4. The daily maintenance of the reducer can be carried out with reference to the instruction manual of the single beam crane manufacturer, and the anchor bolts of the reducer should be checked frequently, and the connection should not be loose.


5、单梁起重机卷扬机组的维护和保养技巧:经常观察减速箱油窗,检查润滑油的油面是否在规定范围之内,如果低于规定的油位的时候,必须及时补充润滑油。

5. Maintenance and maintenance skills of single-beam crane hoisting unit: Always observe the oil tank of the gearbox to check whether the oil level of the lubricating oil is within the specified range. If it is lower than the specified oil level, the lubricating oil must be replenished in time.


6、单梁起重机卷筒两端轴承座内需每两天加注一次润滑脂,卷筒的表面以及钢丝绳要根据情况来涂抹润滑脂。

6. The grease is applied every two days in the bearing housing at both ends of the single beam crane. The surface of the reel and the wire rope should be greased according to the situation.

定、动滑轮组的滚动轴承内需每个月补充一次润滑脂。

The rolling bearing of the fixed and movable pulley block needs to be replenished with grease once a month.
