When loading concrete, if the mixer truck fails, the mixing drum cannot rotate, and the concrete in the mixing drum shall be discharged quickly.

连接紧急驱动软管，依靠其它搅拌车的动力，驱动拌筒旋转并将混凝土排出。但是若减速器同时发生故障时，则不可采用此法。

Connect the emergency drive hose and drive the mixing drum to rotate and discharge the concrete with the power of other mixer trucks. However, if the reducer fails at the same time, this method can not be used.

具体操作步骤如下：准备好一根紧急驱动软管，卸下接管和接头盖。故障车（被驱动车）的操作：将故障车的发动机熄火；将紧固螺母（左右各有一个）朝左旋松；再将旋钮朝右旋转，直到不能再旋为止；将高压软管从马达接头处卸下；将紧急驱动软管接到马达接头上；把紧急驱动软管上的接管与故障车卸下的高压软管相接，以防漏油。

The specific operation steps are as follows: prepare an emergency drive hose, and remove the nozzle and connector cover. Operation of the fault vehicle (driven vehicle): turn off the engine of the fault vehicle; loosen the fastening nut (one on the left and one on the left) to the left; then turn the knob to the right until it can't be rotated again; remove the high-pressure hose from the motor connector; connect the emergency drive hose to the motor connector; connect the connecting the fault vehicle Oil leakage.

自动上料搅拌车的应急处理方式

救援车（驱动车）的操作：将操作手柄于空档位置；将发动机熄火；将高压软管从高压油管处卸下；将紧急驱动软管接到高压油管上；用紧急驱动软管上的接头盖将驱动车的高压软管盖起，以防漏油。启动救援车的发动机；将救援车的操作手柄拨“出料”位置，使故障车内的混凝土排出；紧急驱动完毕后，使两车各自恢复原状。

Operation of rescue vehicle (driving vehicle): set the operating handle to the neutral position; turn off 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 driving vehicle with the joint cover on the emergency drive hose to prevent oil leakage. Start the engine of the rescue vehicle; turn the operation handle of the rescue vehicle to the "discharge" position to discharge the concrete in the fault vehicle; after the emergency drive is completed, make the two vehicles return to their original state.

除上述方法外，或者打开拌筒检修孔的孔盖，旋松高压软管的管接头，将混凝土从拌筒检修孔内排出。注意：放松管接头时，拌筒往往会因此做急速运转，可在拌筒的托轮与滚道之间放入木楔，使拌筒停止转动。

In addition to the above methods, or open the manhole cover of the mixing drum, loosen the pipe joint of the high-pressure hose, and discharge the concrete from the manhole of the mixing drum. Note: when loosening the pipe joint, the mixing drum will often run rapidly. A wooden wedge can be placed between the roller and the raceway to stop the drum from rotating.

安装新的柱塞泵，使拌筒恢复正常运转，从而将混凝土排出；打开拌筒检修孔孔盖，卸下柱塞泵，将混凝土从拌筒检修孔内排出。注意：放松管接头时，拌筒往往会因此做急速运转，可在拌筒的托轮与滚道之间放入木楔，使拌筒停止转动。

Install a new plunger pump to return the mixing drum to normal operation, so as to discharge the concrete; open the manhole cover of the mixing drum, remove the plunger pump, and discharge the concrete from the manhole of the mixing drum. Note: when loosening the pipe joint, the mixing drum will often run rapidly. A wooden wedge can be placed between the roller and the raceway to stop the drum from rotating.
