Method 1

準(zhǔn)備好緊急驅(qū)動(dòng)軟管，將故障水泥自動(dòng)攪拌車熄火，卸下液壓馬達(dá)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(dá)的高壓油管卸下，并與故障車上的對(duì)應(yīng)接頭用緊急驅(qū)動(dòng)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(fā)動(dòng)救援車，將其操縱手柄撥出料位置，故障車內(nèi)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(qū)動(dòng)完畢后，將驅(qū)動(dòng)軟管卸下，并恢復(fù)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(dòng)攪拌車托輪和滾道之間放入木楔，以控制攪拌筒的旋轉(zhuǎn)，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;

將發(fā)動(dòng)機(jī)熄火，拆松液壓馬達(dá)的一根高壓油管，攪拌筒可自由旋轉(zhuǎn)，控制攪拌筒的旋轉(zhuǎn)，使維修孔轉(zhuǎn)到下部，然后打開維修孔，清理出筒內(nèi)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(fù)水泥自動(dòng)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(nóng)村建設(shè)的施工利器以其機(jī)動(dòng)靈活、效率高而廣受好評(píng)。越來(lái)越多的人選擇小型混凝土攪拌泵車代替?zhèn)鹘y(tǒng)落后的作業(yè)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(chǎn)品的使用性能，各部分動(dòng)作的平穩(wěn)性、靈活性、底盤行駛、轉(zhuǎn)彎直徑、接近角、離去角、更小離地間隙等是否滿足通過(guò)性要求，發(fā)動(dòng)機(jī)的燃油消耗率等經(jīng)濟(jì)指標(biāo)是否合理、遙控器操作是否可靠、穩(wěn)定?；蔟垯C(jī)械底架、支腿重量，其鋼材均應(yīng)采用高強(qiáng)度細(xì)精粒結(jié)構(gòu)的碳素鋼(調(diào)質(zhì)薄鋼板)，其焊接工藝要求十分嚴(yán)格，否則會(huì)出現(xiàn)焊縫開裂等十分嚴(yán)重的問(wèn)題。小型混凝土攪拌泵車采用全液壓技術(shù)，因此還要考慮所有的液壓技術(shù)是否，液壓遠(yuǎn)見質(zhì)量如何。因其動(dòng)力來(lái)源于發(fā)動(dòng)機(jī)，除考慮發(fā)動(dòng)機(jī)性能與質(zhì)量外，還要考慮汽車底盤的性能、承載力及質(zhì)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.
