The loading body should be in a horizontal stable position, otherwise it is difficult to control the rotation and unloading accurately and extend the operation cycle time.Keep a proper distance between the car body and the truck to prevent a collision between the back of the car body and the truck during the turn;Try to carry out left-turn loading, which can broaden the vision and improve the operation efficiency. At the same time, it can correctly grasp the turning Angle and reduce the turning time.The parking space forest is lower than the excavator, shorten the lifting time of the boom, and the line of sight is good;Sand the car first, then put big stones on it to reduce the impact on the car.
