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.
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:
Safe locking operation:
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.
Release method of security lock:
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.
Precautions for use of mixer truck:
(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) The capacity (weight) and slump of the delivered concrete shall comply with the provisions of the operation manual;
(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) 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) 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) During the transportation of concrete, the mixing drum shall not stop rotating to avoid segregation of concrete.
