Method 1

準備好緊急驅動軟管，將故障水泥自動攪拌車熄火，卸下液壓馬達上的高壓油管接頭。

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

將救援車熄火，將其液壓馬達的高壓油管卸下，并與故障車上的對應接頭用緊急驅動軟管相連。

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.

發動救援車，將其操縱手柄撥至出料位置，故障車內的混凝土即被排出。

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

緊急驅動完畢后，將驅動軟管卸下，并恢復兩車原狀。

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

方法二

Method 2

在水泥自動攪拌車托輪和滾道之間放入木楔，以控制攪拌筒的旋轉，一定要注意安全；

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;

將發動機熄火，拆松液壓馬達的一根高壓油管，攪拌筒可自由旋轉，控制攪拌筒的旋轉，使維修孔轉到下部，然后打開維修孔，清理出筒內混凝土。

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.

混凝土排出完畢后，恢復水泥自動攪拌車原狀。

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

小型混凝土攪拌泵車作為新農村建設的施工利器以其機動靈活、效率高而廣受好評。越來越多的人選擇小型混凝土攪拌泵車代替傳統落后的作業方式。

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.

考察產品的使用性能，各部分動作的平穩性、靈活性、底盤行駛、轉彎直徑、接近角、離去角、更小離地間隙等是否滿足通過性要求，發動機的燃油消耗率等經濟指標是否合理、遙控器操作是否可靠、穩定。惠龍機械底架、支腿重量，其鋼材均應采用高強度細精粒結構的碳素鋼(調質薄鋼板)，其焊接工藝要求十分嚴格，否則會出現焊縫開裂等十分嚴重的問題。小型混凝土攪拌泵車采用全液壓技術，因此還要考慮所有的液壓技術是否先進，液壓遠見質量如何。因其動力來源于發動機，除考慮發動機性能與質量外，還要考慮汽車底盤的性能、承載力及質量等。

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.
