The mobile concrete mixer truck is composed of chassis and special equipment for concrete mixing station transportation. Its special mechanism mainly includes power take-off, front and rear support frame of mixing drum, reducer hydraulic system, mixing drum operating mechanism, cleaning system, etc.

移動式自上料混凝土攪拌罐車工作原理是通過取力設備將底盤的動力取出，并驅動液壓系統的變量泵，把機械能轉化為液壓能傳給定量馬達，馬達再驅動減速機，由減速機驅動攪拌裝置，對混凝土開展攪拌。

The working principle of the mobile concrete mixer is to take out the power of the chassis through the power take-off equipment, drive the variable displacement pump of the hydraulic system, convert the mechanical energy into hydraulic energy and transfer it to the quantitative motor, then the motor drives the reducer, and the reducer drives the mixing device to mix the concrete.

移動式自上料混凝土攪拌罐車運輸混凝土時，發動機功率在一千到一千四百轉/分范疇內運行，在運輸混凝土全過程中，速度不可超出四十公里每小時。

When the mobile concrete mixer transports concrete, the engine power is in the range of 1000 to 1400 rpm. During the whole process of transporting concrete, the speed should not exceed 40 km / h.

移動式自上料混凝土攪拌罐車運行結束，應把攪拌筒內部結構和車體清理整潔，不可以使剩下的混凝土留到筒內。

At the end of the operation of the mobile concrete mixer, the internal structure and car body of the mixing drum shall be cleaned up, and the remaining concrete shall not be left in the drum.

移動式自上料混凝土攪拌罐車在水泵運行時，嚴禁空轉，連續應用時不要超出15分鐘。

When the water pump of the mobile concrete mixer is running, it is strictly forbidden to idle, and the continuous application shall not exceed 15 minutes.

移動式自上料混凝土攪拌罐車儲水箱的水量要常常維持放滿，以便急需，冬天停機后，應將儲水箱水泵水管攪拌筒內的水放凈，并停到向陽不存水的位置，以防凍壞機械設備。

The water storage tank of the mobile concrete mixer should always be kept full so that it is in urgent need. After shutdown in winter, the water in the mixing drum of the water pump and water pipe of the water storage tank should be drained and stopped to the sunny position without water storage, so as to prevent freezing and damage the mechanical equipment.

移動式自上料混凝土攪拌罐車在冬天應及時性安裝保溫套，并應用防凍液對自上料混凝土攪拌罐車加以保護，依據天氣變化拆換燃油標號，確保機械設備的正常的應用。

In winter, the mobile concrete mixer should be timely installed with insulation sleeve, and antifreeze should be applied to protect the concrete mixer, and the fuel label should be removed and replaced according to the weather change, so as to ensure the normal application of mechanical equipment.

在檢查維修移動式自上料混凝土攪拌罐車液壓傳動部分時，應以發動機和液壓泵在沒有壓力的情況下開展。

When inspecting and repairing the hydraulic transmission part of mobile concrete mixer, the engine and hydraulic pump should be used without pressure.
