1. Connect the emergency drive hose during loading and rely on the power of other mixer trucks. Drive the mixing drum to rotate and discharge the concrete. However, if the reducer fails at the same time, this method cannot be used. The specific operation steps are as follows:
（1）筹办好一根告急驱动软管，卸下接收和讨论盖；
(1) Prepare an emergency drive hose and remove the connecting pipe and connector cover;
（2）毛病车（被驱动车）的操纵：将毛病打鱼注册送分 的策念头熄火；将紧固螺母朝左旋松；再将旋钮朝右扭转，直到不能再旋为止；将高压软管从马达讨论处卸下；
(2) Operation of the failed truck (driven truck): turn off the engine of the failed concrete mixer; loosen the fastening nut to the left; turn the knob to the right until it can no longer be screwed; remove the high-pressure hose from the motor connector;
（3）救济车（驱动车）的操纵：将操纵手柄至于空档地位；将策念头熄火；将高压软管从高压油管处卸下；将告急驱动软管接到高压油管上；用告急驱动软管上的讨论盖将驱动车的高压软管盖起，以防漏油。启动救济车的策念头。将救济车的操纵手柄拨至“出料”地位，使毛病车内的混凝土排挤。告急驱动终了后，使两车各自规复原状。
(3) Operation of rescue vehicle (drive vehicle): set the operating handle to the neutral position; shut down the engine; remove the high-pressure hose from the high-pressure oil pipe; connect the emergency drive hose to the high-pressure oil pipe; cover the high-pressure hose of the drive vehicle with the connector cover on the emergency drive hose to prevent oil leakage. Start the engine of the rescue vehicle. Turn the operating handle of the rescue vehicle to "discharge" Position so that the concrete in the failed vehicle can be discharged. After the emergency drive, restore the two vehicles to their original state.
2.加速机破坏。如在任务中呈现加速机俄然破坏，起首需将搅拌筒内的混凝土排挤，以防呈现凝结景象；其次再改换加速机，也可接洽出产厂家。
2. The reducer is damaged. If the reducer is suddenly damaged during operation, first discharge the concrete in the mixing drum to prevent solidification; Secondly, replace the reducer, or contact the manufacturer.
3.柱塞泵产生毛病。非装载时换上新的柱塞泵，使拌筒规复一般运行。
3. The plunger pump fails. When not loaded, replace with a new plunger pump to restore the normal operation of the mixing drum.
4.液压管讨论处渗漏。将讨论拆下，改换密封圈，从头拧紧便可。
4. Leakage at the hydraulic pipe joint. Remove the connector, replace the sealing ring and retighten it.
