step 5, the floating crane (1) works to enable the other lifting hook (2) to move upwards, and then the two lifting slings (5), the connecting hanging strip (3) and the lifting hanging strip (9) on the other lifting hook (2) move upwards, so that the other end of the heavy object (12) moves upwards along with the lifting slings, and the heights of the lifting slings (2) moving upwards to the lifting hook (2) in the step 4 are consistent;
step 6, the floating crane (1) works to enable the two lifting hooks (2) to move upwards simultaneously, the weight (12) is integrally moved to the position, at the moment, of the lowest end of the weight (12), 1500mm away from the ground, whether the weight (12) meets the requirement in the air or not is observed, and if the weight (12) meets the requirement, the whole weight (12) is moved to a specified position through the floating crane (1) to be installed; if the requirements are not met, the pistons of the four lifting slings (5) are controlled by a remote control device to be finely adjusted until the requirements are met, and after the requirements are met, the whole weight (12) is moved to a specified position by the floating crane (1) to be installed;
and 7, in the processes of the steps 4, 5 and 6, the traction end (16) moves to enable the traction rope (15) to move, so that the whole containing box (13) is inclined, and the containing box (13) is ensured not to influence the operation of the lifting sling (5).
