When the full-automatic mixer truck reverses to the pump truck hopper, if there is a professional commander on site, you can first open the chute, rise to a distance about 10cm higher than the pump truck hopper, and then start to reverse, and follow the command of the commander. If there is no commander on site, the chute shall be pulled back obliquely, and then the rotation stop pin of the chute shall be opened to make it rotate freely. Note: the driver must be able to see the status of the chute in the cab.
When reversing, the body should not face the rear of the pump truck. When reversing, the hopper of the pump truck shall be clearly seen. When the chute is close to the hopper of the pump truck, press the brake to observe whether the chute can touch the hopper after free swing. When the chute touches the material trough of the pump truck in advance, it shall stop immediately and move forward for 10-15cm; If the chute contacts the pump truck chute with braking inertia, this position can only be used for normal feeding.
In addition, there are many common driving knowledge to be clear about, such as:
Before starting the mixer truck, put the mixing drum operating handle at the "stop" position.
After the engine of the full-automatic mixer truck is started, the mixing drum shall be rotated at low speed for about 10 minutes to make the hydraulic oil temperature rise above 20 ℃ for operation.
When the mixer truck is parked in the open air, the mixing drum shall be reversed before loading to discharge the ponding and sundries to ensure the quality of concrete.
When the mixer truck is transporting concrete, it is necessary to ensure that the unloading hopper is firmly fixed to avoid swinging due to looseness during traveling, injuring pedestrians or affecting the normal operation of other vehicles.
During the transportation of the mixer truck, keep the mixing drum rotating normally on the flat road. When driving on the road with large slope or poor road conditions, stop the rotation and resume mixing after the road conditions improve.
The water tank of the mixer truck should always be kept full for emergency use. After the shutdown in winter, the water in the tank, water pump, water pipe and mixing drum should be drained and parked in a sunny place without ponding to avoid freezing the machine.
When repairing the hydraulic transmission part of the mixer truck, the engine and hydraulic pump shall be operated without pressure.
When the full-automatic mixer is overhauled, if it needs to be put into the tank for operation, be sure to turn off the vehicle and remove the key to prevent casualties caused by misoperation.
