Method 1

准备好紧急驱动软管，将故障水泥自动搅拌车熄火，卸下液压马达上的高压油管接头。

Prepare the emergency drive hose, turn off the faulty concrete mixer, and remove the high-pressure oil pipe connector on the hydraulic motor.

将救援车熄火，将其液压马达的高压油管卸下，并与故障车上的对应接头用紧急驱动软管相连。

Turn off the rescue vehicle, remove the high-pressure oil pipe of its hydraulic motor, and connect it with the corresponding connector on the faulty vehicle with emergency drive hose.

发动救援车，将其操纵手柄拨出料位置，故障车内的混凝土即被排出。

Start the rescue vehicle and turn its control handle to the discharging position, then the concrete in the failure vehicle will be discharged.

紧急驱动完毕后，将驱动软管卸下，并恢复两车原状。

After the emergency drive, remove the drive hose and restore the two vehicles to their original state.

方法二

Method 2

在水泥自动搅拌车托轮和滚道之间放入木楔，以控制搅拌筒的旋转，一定要注意；

In order to control the rotation of the mixing drum, a wooden wedge is placed between the supporting wheel and the raceway of the concrete mixer truck;

将发动机熄火，拆松液压马达的一根高压油管，搅拌筒可自由旋转，控制搅拌筒的旋转，使维修孔转到下部，然后打开维修孔，清理出筒内混凝土。

Turn off the engine and loosen a high-pressure oil pipe of the hydraulic motor. The mixing drum can rotate freely. Control the rotation of the mixing drum to turn the maintenance hole to the lower part. Then open the maintenance hole and clean up the concrete in the drum.

混凝土排出完毕后，恢复水泥自动搅拌车原状。

After the concrete is discharged, the concrete mixer truck shall be restored to its original state.

小型混凝土搅拌泵车作为新农村建设的施工利器以其机动灵活、效率高而广受好评。越来越多的人选择小型混凝土搅拌泵车代替传统落后的作业方式。

As a sharp tool of new rural construction, small concrete mixing pump truck is widely praised for its flexibility and high efficiency. More and more people choose small concrete mixing pump truck to replace the traditional backward operation mode.

考察产品的使用性能，各部分动作的平稳性、灵活性、底盘行驶、转弯直径、接近角、离去角、更小离地间隙等是否满足通过性要求，发动机的燃油消耗率等经济指标是否合理、遥控器操作是否可靠、稳定。惠龙机械底架、支腿重量，其钢材均应采用高强度细精粒结构的碳素钢(调质薄钢板)，其焊接工艺要求十分严格，否则会出现焊缝开裂等十分严重的问题。小型混凝土搅拌泵车采用全液压技术，因此还要考虑所有的液压技术是否，液压远见质量如何。因其动力来源于发动机，除考虑发动机性能与质量外，还要考虑汽车底盘的性能、承载力及质量等。

The service performance of the product, the smoothness and flexibility of each part of the action, chassis driving, turning diameter, approach angle, departure angle, minimum ground clearance, etc. meet the trafficability requirements, the fuel consumption rate and other economic indicators of the engine are reasonable, and the remote control operation is reliable and stable. For the weight of underframe and outrigger of Huilong machinery, the steel should be carbon steel (quenched and tempered steel sheet) with high strength and fine grain structure. The welding process requirements are very strict, otherwise there will be serious problems such as weld cracking. Small concrete mixing pump truck adopts full hydraulic technology, so it is necessary to consider whether all the hydraulic technology is advanced and how the hydraulic quality is. Because its power comes from the engine, in addition to the performance and quality of the engine, the performance, bearing capacity and quality of the chassis should also be considered.
