裝載機現場如何快速更換輪胎？

由于裝載機在比較惡劣的工地(比如巖石面)工作時經常發生爆胎，永保機械總結出一條快速更換裝載機輪胎的方法，具體如下：

(1)首先啟動機器，然后尋找一塊平坦開闊的場地，壓下動臂升降桿，利用動臂支撐使前輪離地，然后用支架支撐在閃橋靠近爆胎的一側，并將后輪楔好。
First, start the machine, and then look for a flat open space, depressed boom lift lever arm support to make use of the front wheel off the ground, and then use the flash on the side of the bridge support bracket near the puncture and rear wedge good.
(2)利用撬杠等工具，拆卸擋圈及鎖圈然后檢查輪胎襯墊與輪輞外表面是否粘連。若發生可撤掉支撐物，使機器在短距離內慢速往復運行，直至襯墊與輪輞外表面脫離；嚴禁轉向和高速行駛，以免損壞內胎。然后，前輪重新支撐起來。
Use of crowbars and other tools, removing the retainer ring and lock ring and then check the tire and rim outer surface of the liner is adhesions. Support can be removed, if occurs, the machine is running slow reciprocating within a short distance, until the outer surface of the liner from the wheel rim; steering and non-high speed, to avoid damaging the tube. Then, to prop up the front again.
(3)將內、外胎的相對位置作好標記，以便查找、清除異物和修補輪胎。

(4)利用撬杠等工具，將輪胎從輪輞上拆下。注意，動作要輕柔配合要默契，避免被輪胎砸傷，并且要保護好氣門嘴。
Use of crowbars and other tools to remove the tire from the rim. Note that the action should be gentle with the tacit agreement to avoid being injured by a tire, and to protect the valve.
(5)外胎被釘子等細長異物扎傷后，若表面無明顯創口或創口較小，則此外胎可繼續使用(因為裝載機輪胎屬低壓胎，且運行速度比較慢)；若創口較大，則必須進行修補(因為機器運行時，輪胎受擠壓磨擦，時間一長就會損壞內胎，甚至創口越來越大、內胎突出，造成輪胎報廢。
Nails and other foreign objects slim casing after being stabbed, if no obvious wounds or wound surface is small, then the fetus can also continue to use (because loader tire is low pressure tires, and run more slowly); If the wound is large, it must repair (because the machine is running, by squeezing the tire friction, over time will damage the inner tube, and even wound growing, highlighting the tube, causing the tire scrap.
(6)若是新內胎，必須將氣門嘴底部的螺栓擰緊，以防漏氣；然后將外胎內腔的異物清除，并撒入適當的滑石粉，涂抹均勻。為了使襯墊與內、外胎貼緊，在裝入內胎后應給內胎適當充氣，再塞入襯墊。
If a new inner tube, valve at the bottom of the bolts must be tightened to prevent leakage; then the tire cavity foreign body removal, and thrown into the appropriate talcum powder, spread evenly. In order to make the inner liner, tire snapping, after loading tube to tube should be properly inflated, and then stuffed cushions.
(7)將輪胎裝到輪輞上，裝上鎖圈、擋圈；安裝過程中要保護好氣門嘴。

(8)用車載空壓機給輪胎充氣。

(9)壓下動臂升降桿，取出支架；至此換胎完畢，整個過程大約需要50min。
Depressed boom lift rod, remove the bracket; thus tire change is completed, the entire process takes about 50min.

更換后輪胎時，則需要另一臺裝載機或者其他起重設備輔助，將后輪胎支撐起來，其他程序則與更換前輪胎相同。
When replacing the tires, you need another loader or other auxiliary lifting equipment, propped up the rear tires, and replace other procedures are the same as the front tires.
