When the small soil mixer truck loads the mixed concrete, the speed of the mixing drum is 2-10 R / min. during transportation, the speed of the mixing drum on the flat road shall be 2-3 R / min. when driving on the road with a roll gradient greater than 50 or the road with large shaking left and right, the mixing and rotation shall be stopped, and the mixing and rotation shall be resumed after the road conditions improve.

攪拌車(chē)的混凝土攪拌時(shí)間不能超過(guò)攪拌站規定的時(shí)間。運送混凝土途中，攪拌筒不得長(cháng)時(shí)間停轉，以防混凝土產(chǎn)生離析現象。司機應時(shí)常觀(guān)察混凝土情況，發(fā)現異常及時(shí)通報調度室，申請做出處理。攪拌車(chē)車(chē)內裝有混凝土時(shí)，在現場(chǎng)停滯時(shí)間不得超過(guò)1小時(shí)，如超時(shí)應立即要求現場(chǎng)負責人給予及時(shí)處理。

When the mixer truck is loaded with concrete, the standstill time on the site shall not exceed 1 hour. In case of overtime, the person in charge of the site shall be required to deal with it in time.

攪拌車(chē)運送混凝土塌落度不得低于8cm。從混凝土入罐到排出，氣溫高時(shí)不得超過(guò)2小時(shí)須排出，陰雨天氣溫度低時(shí)，不得超過(guò)2.5小時(shí)。攪拌車(chē)在排出混凝土之前，應使攪拌筒在10-12轉/分的轉速下轉動(dòng)1分鐘，再進(jìn)行排料。

The slump of concrete transported by mixer truck shall not be less than 8cm. The concrete shall not be discharged for more than 2 hours when the temperature is high, and not more than 2.5 hours when the temperature is low in cloudy and rainy weather.
