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

制动器失灵会导致伤亡事故。 如果由于制动系统故障,使制动器合紧时,不要开动机器。

开动机器前,要先把问题解决。


    注: 停车制动器位于终传动行星齿轮(滚筒)上。

  1. 牢牢地楔住钢轮和轮胎,以防机器移动。

  2. 为刚性固定前后机架,装上转向机架锁销。

  3. 当使用下列步骤时,可释放制动器。


    图 2g00040674

  4. 要释放制动器,请使用 FT-1973 适配器总成和 FT-1845 泵总成。

  5. 将制动器释放软管连接到 FT-1973 适配器总成 (5)。

  6. 将旁通的手柄 (4) 转至 CLOSED(关闭)位置。

  7. 当操作泵手柄 (3) 时,观察泄压阀 (2) 开口的压力。


    注意

    不检查泄压阀,可能会造成制动器柱塞密封的可能损坏。 在进行连接前,必须检查和调整开口压力。


  8. 将开口的压力调节到 2413 ± 69 kPa (350 ± 10 psi)。 将旁通的手柄 (4) 转至 OPEN(打开)位置。

  9. 断开制动管。 塞住制动管,以防液体损失。

    注: 视机器配置而定,推进泵上可能连接有两条制动管。 从泵上拆下连接两条管路的 T 接头。

  10. 根据具体的配置,将 8T-2857 制动器释放适配器连接到制动管,或者连接到两条制动管之间的 T 接头。 将 FT-1973 适配器总成 (5) 的其余部分连接到泵压力软管上。

  11. 将泵放在靠近操作员处。

  12. 将旁通的手柄 (4) 转至 CLOSED(关闭)位置。

  13. 操作泵手柄,以使压力升高。 当密封正确固定后,压力将增加到最大。

  14. 当发动机停止时,在牵引机器前,需要采取更多步骤。 有关详细资料,请参阅操作和保养手册, "牵引机器"。

  15. 现在可以牵引机器了。

只能短距离牵引机器。 以低于 2 km/h (1.2 mph) 的低速度牵引机器。
