集材作业机的轮胎常年工作在简易集材道上和无路可走的森林里。林地上的枝丫、伐根、“马耳茬”等障碍物对轮胎的正常工作是个严重的威胁。它可以使轮胎造成异常磨损,而且常常使轮胎造成严重的划割、刺伤或刺穿。“营林—35集材机”生产试验表明,每班生产作业中扎入轮胎表层的树茬至少有十数个。这些树茬扎入轮胎表面深度多为20～30毫米,最深达50毫米。在检查轮胎表面被刺伤痕时,可以明显看到还有更多的刺扎伤口,只是树茬没有留在轮胎表面胶层里而已。由于轮胎的异常磨损和刺扎损坏,使轮
Skidding work tire machine perennial work in the simple skidding Road and the path of the forest. Obstacles such as sticks, stumps and “stubble” on the woodland are a serious threat to the normal operation of the tire. It can cause abnormal wear and tear on the tire, often causing severe cuts, punctures or punctures. “Ying Lin-35 skidder” production tests show that each class of production operations into the tire surface stubble at least a dozen. These stubble into the tire surface depth of mostly 20 to 30 mm, the deepest up to 50 mm. When examining the stab wounds on the tire surface, it is clear that there are more punctured wounds, except that the stubble does not remain in the rubber layer on the tire surface. Due to abnormal tire wear and puncture damage, make the wheel
