The automatic mixer truck will carry out trial operation when transporting heavy-duty concrete. Do you know how it carries out trial operation? Here are the steps.
1. Determine the water supply according to the required concrete ratio, and adjust the time relay to the corresponding water supply time.
2. Start the mixing motor.
3. Close the discharge door and add the required mixture into the hopper. After lifting the hopper, the hopper should run smoothly and stop at any position of the track freely. If there is slippage, the hopper should first be put into the bottom of the pit and then adjust the large nut on the brake motor. After the hopper lifting is normal and the brake is reliable, the material is fed into the mixing tank, and the water pump is started to supply water to the mixing tank.
4. After mixing for 25-35 seconds, start the discharge valve to discharge.
5. In the process of the above test run, if any abnormality is found, stop the machine immediately for inspection, remove the fault, and then test again until it is normal.
The heavy load trial run of the automatic mixer truck is just like the above. It is very necessary to carry out the trial run when the truck is under heavy load. The drivers must pay attention to it.
