When using a crane to lift a large water-absorbing stone onto a flatbed truck in the mountains, the following issues need to be noted. Firstly, ensure the stability and safety of the crane. Select a proper parking position and check whether the outriggers of the crane are firmly fixed. Secondly, choose appropriate lifting tools such as wire ropes and hooks according to the weight and size of the water-absorbing stone, and make sure that the lifting tools are in good condition and have sufficient load-bearing capacity. Before lifting, accurately calculate the position of the center of gravity and reasonably adjust the position of the hook to ensure that the water-absorbing stone remains balanced during the lifting process. When lifting, do it slowly and steadily, avoiding sudden starts and stops to prevent the water-absorbing stone from shaking, slipping or colliding. Meanwhile, arrange a dedicated person to direct the operation of the crane to ensure smooth communication between the operator and the director and that the operation is carried out strictly in accordance with the instructions. In addition, when placing the water-absorbing stone onto the flatbed truck, pay attention to the position and method of placement to ensure that the flatbed truck can bear the weight of the water-absorbing stone and that the placement is stable. If necessary, fix the water-absorbing stone to prevent it from moving during transportation.
