Since the feeding mixer can only operate the boom after confirming that the support legs of the pump truck have been properly supported, the operation of the boom must be carried out in accordance with the sequence described in the operating procedures. Now let's take a look at the operation of the boom.

雷雨或惡劣天氣情況下，自上料攪拌車不能使用臂架。臂架不能在大于8級風力的天氣中使用；操作攪拌車臂架時，臂架的全部都應在操作者的視野內。

In case of thunderstorm or bad weather, boom cannot be used for self loading mixer. The boom can not be used in the weather with wind force greater than 8; when operating the boom of the mixer, all parts of the boom should be in the view of the operator.

攪拌車在高壓線附近作業時要小心觸電的危險，應保證臂架與電線的安全距離；臂架下方是危險區域，可能有混凝土或其它零件掉落傷人；末端軟管規定的范圍內不得站人，攪拌車啟動泵送時不得引導末端軟管，它可能會擺動傷人或噴射出混凝土引起事故。

When the mixer is working near the high-voltage line, it is necessary to be careful of the danger of electric shock and ensure the safe distance between the boom and the electric wire; below the boom is a dangerous area where concrete or other parts may fall and hurt people; people are not allowed to stand within the specified range of the end hose, and the end hose should not be guided when the mixer starts pumping, which may swing and hurt people or spray concrete to cause accidents.

啟動攪拌車時的危險區就是末端軟管擺動的周圍區域。區域直徑是末端軟管長度的兩倍。末端軟管長度較大為3m，則危險區域直徑為6m；切勿折彎攪拌車末端軟管，末端軟管不能末入混凝土中。

The dangerous area when starting the mixer is the area around the swing of the end hose. The area diameter is twice the length of the end hose. If the length of the end hose is larger than 3m, the diameter of the dangerous area is 6m; do not bend the end hose of the mixer truck, and the end hose cannot end into the concrete.

如果攪拌車臂架出現不正常的動作，就要立即按下急停按鈕。由人員查明原因并排除后方可繼續使用。

If there is abnormal action of the mixer boom, press the emergency stop button immediately. It can be used only after the cause is found out and eliminated.

以上就是關于攪拌車的臂架操作介紹。臂架作為一個備用的支撐，在使用時一定要規范操作，另外要注意臂架與電線的安全距離。

The above is about the mixer boom operation. Boom as a backup support, in use must be standardized operation, in addition to pay attention to the safe distance between the boom and the wire.
