------ WARNING! ------

润滑脂有很高的压力。

润滑脂在压力下喷出卸压阀能够穿透身体,造成伤亡。

不要通过泄压阀来观察润滑脂是否溢出。 应观察履带或履带调整油缸来查看履带是否松动。

只要转一圈,以便把卸压阀松开。


向前移动机器。 在不使用行车制动器的情况下让机器停止。 当机器处于一般工作状态时,调整履带。 如果工作场所填料较多,则应在带有填料的情况下来调节履带。

如果机器没有托链轮,则要测量链轮和前引导轮之间的履带是否松弛。 尺寸 (2) 的正确调整值应为 130 ± 10 mm (5.1 ± 0.4 in)。




图 2g00104000

如果机器配备有托链轮,则应计算尺寸 (3) 和尺寸 (4) 的和。 和等于 130 ± 10 mm (5.1 ± 0.4 in) 时即可获得正确的下垂度。

注意

当尺寸 (1) 为 150 mm (5.9 in) 或以上时不要试图拧紧履带。

联系您的 Caterpillar 代理商了解履带维修或相关说明。
