If various types of mixer truck are operated improperly during use, it will cause many accidents or problems, such as rollover, rapid wear of hydraulic pump, motor and reducer, and even serious consequences. So how should we deal with it?
Before starting the mixer truck, put the operating handle of the mixing drum in the "stop" position. After starting the engine of the mixer truck, make the mixing drum rotate at low speed for about 10 minutes, and make the hydraulic oil temperature rise to more than 20 ℃. When the mixer truck is parked in the open air, the mixing drum shall be reversed before loading to discharge the ponding and sundries, so as to ensure the quality of concrete.
When transporting concrete, the mixer shall ensure that the sliding bucket is firmly placed to prevent swinging due to looseness, injuring pedestrians or affecting the normal operation of other vehicles. When the mixer truck is loaded with concrete, the stagnation time at the site shall not exceed 1 hour. If it exceeds the time limit, the person in charge of the site shall be required to deal with it in time.
When the mixer truck transports the mixed concrete, the speed of the mixing drum is 2-10 R / min. during transportation, the speed of the mixing drum on the flat road is guaranteed to be 2-3 R / min. when driving on the road with a side slope greater than 50 or the road with large shaking left and right, the mixing and rotation shall be stopped and resumed after the road conditions improve.
The time for transporting concrete by concrete mixer truck shall not exceed the time specified by the mixing plant. During the transportation of concrete, the mixing drum shall not stop for a long time to prevent segregation of concrete. The driver shall always observe the concrete condition, report any abnormality to the dispatching room in time and apply for handling.
If the engine overheats on ordinary roads, you should reduce the speed as soon as possible, drive the car to the shade of trees or to a relatively cool place, and stop the car. Open the engine hood, let the engine run at idle speed, and wait for the engine temperature to gradually return to normal. After the engine water temperature returns to normal, turn off the engine.
Then wait for a period of time until the water temperature of the engine drops sufficiently, and then check the cooling water volume of the engine. At this time, the cooling water of the engine is mostly seriously insufficient. After replenishing the cooling water according to the specified amount, check the cooling system. After confirming that there are no other faults, start the engine and continue driving.
The water volume of the water tank of the concrete mixer truck shall be kept full for emergency use. After shutdown in winter, the water in the water tank, water pump, water pipe and mixing drum shall be drained and parked in a place with no ponding in the sun to avoid freezing the machine. In winter, the thermal insulation sleeve shall be installed in time, the anti freezing liquid shall be used to protect the mixer, and the fuel grade shall be changed according to the weather change to ensure the normal use of the machinery.
The concrete mixer truck will be under the car through the power take-off device. I. before starting, all parts of the mechanical system shall be carefully inspected and can be started only after it is confirmed to be good, so as to ensure that both equipment and personnel are not injured.
