1. The capacity, quality and slump of concrete delivered by the concrete mixer truck should meet the standards and requirements of the concrete industry.
2. The tank system of the large-scale mixing tank truck stops during the transportation of concrete to avoid the formation of coagulation of the concrete. When it stops and restarts, it will cause an impact on the hydraulic system and reducer, resulting in damage to the hydraulic pump and motor.
3. When the small mixer truck travels on the road, it is necessary to place the lengthened chute on the unloading chute bracket and hang it with hooks. It is not allowed to hang on the main discharge chute for work; the main discharge chute should be rotated to a fixed position and pulled down. Position the handle, and lock the spring luffing mechanism with the locking handle to avoid shaking due to unfixedness, which may cause injury to people and affect the work of other vehicles.
4. The continuous working time of the operating equipment should not exceed 8h.
5. When unloading, if it is found that the water evaporates and the slump is too low to meet the user's requirements, water can be appropriately added to the cylinder, and then the cylinder is rotated at a speed of 10-14r/min for 30 revolutions before unloading, so that the concrete is fully mixed.
6. During the no-load operation of the mixer truck, the mixing drum must not be stopped to avoid the collision of the raceway and the supporting wheel during fluctuations, resulting in abnormal damage to the supporting wheel and the raceway.
7. The water volume of the water tank should be filled up frequently for emergency use. Before adding water to the water tank, it is necessary to open the air valve to release the air in the tank; open the air valve when flushing, and release the gas in the water tank when the flushing is over or stopped. When parked in winter, there must be no remaining water in the water tank and water supply system to avoid freezing and cracking. Note: The water tank is only pressurized when supplying water, do not travel on the road with a pressurized water tank.
8. The concrete mixing tank truck is rotating forward with full load of concrete. If it wants to rotate, it is necessary to operate the handle to stop the forward rotation, and then operate the handle to rotate. It is forbidden to operate the handle to make it rotate during the forward rotation. mixer truck price
The above are the eight things to pay attention to in the work of concrete mixer truck, I hope to help you.
