安全鎖定機構的作用，是防止小型混凝土攪拌車的拌筒，在攪拌車行駛時，因操縱手柄被樹枝或其它障礙物鉤住而作出料旋轉。下面就來講講攪拌車的安全鎖定機構與使用方法吧。

The function of the safety locking mechanism is to prevent the mixing drum of the small concrete mixer from rotating due to the operating handle being hooked by branches or other obstacles when the mixer is running. Let's talk about the safety locking mechanism and use method of the mixer truck.

如行駛時，誤將混凝土排出，則對于行人，后面的車輛以及反方向行駛的車輛，均危險!使用方法：

If the concrete is discharged by mistake when driving, it is dangerous for pedestrians, vehicles behind and vehicles driving in the opposite direction! usage method:

安全鎖定的操作：

Safe locking operation:

須將操作手柄固定在攪動位置，將駕駛室內推拉軟軸操作手柄卡在定位塊的槽中即可。

The operating handle must be fixed at the stirring position, and the push-pull flexible shaft operating handle in the cab can be clamped in the slot of the positioning block.

安全鎖定的解除方法：

Release method of security lock:

混凝土出料前，將駕駛室內推拉軟軸操作手柄從定位塊的槽中推出即可解除鎖定。

Before concrete discharging, push the push-pull flexible shaft operating handle in the cab out of the slot of the positioning block to release the lock.

攪拌車使用時注意事項：

Precautions for use of mixer truck:

(1)新車開始使用時，須進行全面檢查和試車，一切正常時，方可正式使用；

(1) When the new car is put into use, it must be comprehensively checked and tested. It can be officially used only when everything is normal;

(2)輸送混凝土的容量(重量)及坍落度應符合使用說明書的規定；

(2) The capacity (weight) and slump of the delivered concrete shall comply with the provisions of the operation manual;

(3)攪拌車在露天停放時，裝料前應先將攪拌筒反轉，把筒內的積水和雜物卸出，以保證運送混凝土的質量；

(3) When the mixer truck is parked in the open air, the mixing drum shall be reversed before loading, and the accumulated water and sundries in the drum shall be discharged to ensure the quality of concrete transported;

(4)行駛時，加長溜槽須翻轉放置在卸料溜槽上用掛鉤掛牢，再轉至與車身垂直部位，用鎖緊裝置把卸料溜槽和加長溜槽鎖緊在機架上，防止由于不固定而搖動，造成事故；

(4) When driving, the extended chute must be overturned and placed on the discharge chute, hung firmly with a hook, and then turned to the vertical part with the vehicle body. Lock the discharge chute and the extended chute on the frame with a locking device to prevent shaking due to instability and accidents;

(5)卸料前，發現混凝土坍落度偏低，不能滿足用戶要求時，可適當向拌筒內加水，然后以12-14r/min的速度旋轉30轉后卸料；

(5) Before unloading, if it is found that the slump of concrete is too low to meet the user's requirements, water can be added to the mixing drum appropriately, and then the concrete can be unloaded after rotating for 30 revolutions at the speed of 12-14r / min;

(6)運輸車在運送混凝土的過程中，攪拌筒不得停止轉動，以免混凝土產生離析。

(6) During the transportation of concrete, the mixing drum shall not stop rotating to avoid segregation of concrete.

攪拌車的安全鎖定機構與使用方法就是這樣了。

This is the safety locking mechanism and use method of the mixer truck.
