單梁起重機(jī)保都有規(guī)定的額定壽命，但這些其實(shí)都只能作為一個參考數(shù)據(jù)，如果日常生活中你多加用心呵護(hù)的話，單梁起重機(jī)保的性能將會超出規(guī)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(jī)保的維護(hù)保養(yǎng)和操作較為疏忽的話，那么單梁起重機(jī)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(nèi)?日常單梁起重機(jī)檢查中經(jīng)常發(fā)現(xiàn)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(dǎo)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(jī)電機(jī)固定是否牢固，電機(jī)墜落的案例也很多，只是正好砸中人員的情況不多。因?yàn)殡姍C(jī)(大車電機(jī))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(dǎo)致固定止松動引發(fā)。起重機(jī)的解決方式值得我們?nèi)ソ梃b：在電機(jī)上加裝防墜鎖，在電機(jī)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(jī)標(biāo)配都是變速運(yùn)行，這種情況下起重設(shè)備運(yùn)行非常平穩(wěn)，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(jī)，相比單梁起重機(jī)**、穩(wěn)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(jī)如何保養(yǎng)維護(hù)

How to maintain and maintain a single beam crane

1、經(jīng)常檢查單梁起重機(jī)電動機(jī)外殼以及軸承部位的溫度、電動機(jī)的噪音、振動有無異常現(xiàn)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(jī)在頻繁啟動情況下，由于轉(zhuǎn)速低引起通風(fēng)冷卻能力的降低，而且電流較大，電機(jī)溫升會很快的提高，應(yīng)當(dāng)要注意電機(jī)溫升不能超過其說明書上規(guī)定的上限值，按照電動機(jī)使用說明書的要求調(diào)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(jī)使用不是很頻繁且又密封狀況和使用環(huán)境良好的情況下，單梁起重機(jī)減速箱內(nèi)的潤滑油每半年需要更換一次，單梁起重機(jī)在使用環(huán)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(fā)現(xiàn)箱內(nèi)進(jìn)水或是油面始終有泡沫并且確定油已經(jīng)變質(zhì)的時候，必須立即換油，換油時應(yīng)嚴(yán)格按照減速箱使用說明書規(guī)定的油品進(jìn)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(jī)的日常維護(hù)可以參考單梁起重機(jī)生產(chǎn)廠家的使用說明書來進(jìn)行維護(hù)，并且要經(jīng)常檢查減速機(jī)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(jī)卷揚(yáng)機(jī)組的維護(hù)和保養(yǎng)技巧：經(jīng)常觀察減速箱油窗，檢查潤滑油的油面是否在規(guī)定范圍之內(nèi)，如果低于規(guī)定的油位的時候，必須及時補(bǔ)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(jī)卷筒兩端軸承座內(nèi)需每兩天加注一次潤滑脂，卷筒的表面以及鋼絲繩要根據(jù)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(nèi)需每個月補(bǔ)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.
