單梁起重機保都有規定的額定壽命，但這些其實都只能作為一個參考數據，如果日常生活中你多加用心呵護的話，單梁起重機保的性能將會超出規定的使用壽命。

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對單梁起重機保的維護保養和操作較為疏忽的話，那么單梁起重機保將有可能提前衰老。

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.

電動葫蘆小車間隙是否在正常范圍內?日常單梁起重機檢查中經常發現有些葫蘆小車與主梁工字鋼的間隙明顯過大。

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.

由于葫蘆是靠小車掛在工字鋼上的，如果間隙大于工字鋼面寬就有可能掛不住。導致整個葫蘆墜落，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.

單梁起重機電機固定是否牢固，電機墜落的案例也很多，只是正好砸中人員的情況不多。因為電機(大車電機)一般在靠邊的位置。

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.

墜落原因主要是單梁行車操作過程中的振動導致固定止松動引發。起重機的解決方式值得我們去借鑒：在電機上加裝防墜鎖，在電機墜落時可以拉住不*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.

歐式起重機標配都是變速運行，這種情況下起重設備運行非常平穩，幾乎沒有振動。

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

主梁與端梁連接螺絲有無松動，造成這個隱患的主要原因也是振動，因此建議使用盡量選用變速起重機，相比單梁起重機**、穩定、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.

單梁起重機如何保養維護

How to maintain and maintain a single beam crane

1、經常檢查單梁起重機電動機外殼以及軸承部位的溫度、電動機的噪音、振動有無異常現象。

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、單梁起重機在頻繁啟動情況下，由于轉速低引起通風冷卻能力的降低，而且電流較大，電機溫升會很快的提高，應當要注意電機溫升不能超過其說明書上規定的上限值，按照電動機使用說明書的要求調整制動器。

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、在單梁起重機使用不是很頻繁且又密封狀況和使用環境良好的情況下，單梁起重機減速箱內的潤滑油每半年需要更換一次，單梁起重機在使用環境惡劣的情況下，每個季度需要更換一次。

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.

發現箱內進水或是油面始終有泡沫并且確定油已經變質的時候，必須立即換油，換油時應嚴格按照減速箱使用說明書規定的油品進行更換，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、減速機的日常維護可以參考單梁起重機生產廠家的使用說明書來進行維護，并且要經常檢查減速機的地腳螺栓，連接不可松動。

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、單梁起重機卷揚機組的維護和保養技巧：經常觀察減速箱油窗，檢查潤滑油的油面是否在規定范圍之內，如果低于規定的油位的時候，必須及時補充潤滑油。

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、單梁起重機卷筒兩端軸承座內需每兩天加注一次潤滑脂，卷筒的表面以及鋼絲繩要根據情況來涂抹潤滑脂。

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、動滑輪組的滾動軸承內需每個月補充一次潤滑脂。

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