As one of the heavy machinery commonly used in the engineering industry, loader forklift has a bad working environment, long working time and large load, which will cause certain loss to the loader. Because the front wheel bears the load, steering and driving functions, and first contacts with foreign matters on the ground, it is more prone to tire burst. However, due to the heavy weight of loader and the limitation of site and tools, it is difficult to replace. Here, Shanqi heavy industry summed up a set of methods for quick on-site tire replacement, as follows.

1.啟動(dòng)機(jī)器，就近尋找一塊比較平坦開闊的場地，壓下動(dòng)臂升降桿，利用動(dòng)臂支承使前輪離地，然后用支架支撐在前橋靠近爆胎的一側(cè)，并將后輪楔好，這一過程必 須與駕駛員密切配合，以免造成 人身傷害。

1. Start the machine, find a relatively flat and open place nearby, press down the boom lifting rod, use the boom support to lift the front wheel off the ground, and then use the bracket to support the side of the front axle near the tire burst, and wedge the rear wheel well. This process must be closely coordinated with the driver to avoid personal injury.

2.利用撬杠等工具，拆卸擋圈及鎖圈然后檢查裝載機(jī)輪胎襯墊與輪輞外表面是否粘連。若發(fā)生可撤掉支撐物，使機(jī)器在短距離內(nèi)慢速往復(fù)運(yùn)行，直襯墊與輪輞外表面脫離，此時(shí)需要注意嚴(yán)禁轉(zhuǎn)向和高速行駛，以免損壞內(nèi)胎。然后，前輪重新支撐起來。

2. Use crowbar and other tools to remove the retaining ring and lock ring, and then check whether the tire liner of loader adheres to the outer surface of rim. In case of any accident, the support can be removed to make the machine run back and forth slowly in a short distance until the liner is separated from the outer surface of the rim. At this time, it is necessary to pay attention to strictly prohibit steering and high-speed driving to avoid damaging the inner tube. Then, the front wheels are propped up again.

3.將內(nèi)、外胎的相對(duì)位置作好標(biāo)記，以便查找、清 除異物和修補(bǔ)輪胎。

3. Mark the relative position of the inner and outer tires, so as to find, remove foreign matters and repair the tires.

4.利用撬杠等工具，將輪胎從輪輞上拆下。注意，動(dòng)作要輕柔配合要默契，避免被輪胎砸傷，并且要保護(hù)好氣門嘴。

4. Use crowbar and other tools to remove the tire from the rim. Note that the movement should be gentle, cooperate with tacit understanding, avoid being hurt by the tire, and protect the valve mouth.

5.外胎被釘子等細(xì)長異物扎傷后，若表面無明顯創(chuàng)口或創(chuàng)口較小，則此外胎可繼續(xù)使用；若創(chuàng)口較大，則必 須進(jìn)行修補(bǔ)以防時(shí)間一長就會(huì)損壞內(nèi)胎，甚創(chuàng)口越來越大、內(nèi)胎突出，進(jìn)而造成輪胎報(bào)廢。

5. If there is no obvious wound or small wound on the surface of the outer tube after it is injured by nails and other slender foreign bodies, the outer tube can continue to be used; If the wound is large, it must be repaired to prevent the damage to the inner tube after a long time, or even the wound becomes larger and larger, the inner tube protrudes, and then the tire is scrapped.

6.若是新內(nèi)胎，必 須將氣門嘴底部的螺栓擰緊，以防漏氣，然后將外胎內(nèi)腔的異物，并撒入適當(dāng)?shù)幕燮扑闄C(jī)，涂抹均勻。為了使襯墊與內(nèi)、外胎貼緊，在裝入內(nèi)胎后應(yīng)給內(nèi)胎適當(dāng)充氣，再塞入襯墊。

6. If it is a new inner tube, the bolts at the bottom of the valve must be tightened to prevent air leakage, and then the foreign matters in the inner cavity of the outer tube shall be removed, and the suitable talcum powder crusher shall be sprinkled, and the coating shall be uniform. In order to make the liner close to the inner and outer tubes, the inner tube should be properly inflated and then the liner should be inserted.

7將輪胎裝到輪輞上，裝上鎖圈、擋圈;安裝過程中要保護(hù)好氣門嘴，并用車載空壓機(jī)給輪胎充氣。壓下動(dòng)臂升降桿，取出支架，此換胎完畢，整個(gè)過程大約需要50分鐘。

7. Install the tire on the rim and install the lock ring and retaining ring; In the process of installation, the valve mouth should be well protected and the tires should be inflated with the on-board air compressor. Press down the boom lifting rod, take out the bracket, and then the tire change is completed. The whole process takes about 50 minutes.

需要注意的是，更換輪胎時(shí)需要另一臺(tái)裝載機(jī)或其他起重設(shè)備作為輔助，將后輪支撐起來，更換流程與上述一樣。在此，山汽重工提醒廣大機(jī)友，在更換中要尤其注意安 全，同時(shí)，在日常的操作中要對(duì)工況環(huán)境做預(yù)先考察，清 除現(xiàn)場的雜物和易對(duì)裝載機(jī)部件造成損壞的雜物，保障作業(yè)的正常進(jìn)行及操作人員的安 全，同時(shí)延長機(jī)器使用壽命。

It should be noted that another loader or other lifting equipment is needed to support the rear wheel when changing the tire. The replacement process is the same as above. In this regard, Shanqi heavy industry reminds the majority of the machine friends that they should pay special attention to safety in replacement. At the same time, in daily operation, they should make a pre inspection on the working condition environment, remove the debris on the site and the debris that is easy to damage the loader parts, ensure the normal operation and the safety of the operators, and extend the service life of the machine.
