For horizontal hoisting, the correct hoisting method can be adopted according to the characteristics of the heavy object, and the heavy object can be leveled by the following methods.
1 Rope-shifting leveling method
The so-called moving rope leveling method is a method of using the movement of the sling at the binding point or on the hook to change the position of the hoisting force point or change the length of the force strand to level the heavy object. This method is suitable for slender heavy objects and horizontal hoisting work of two-point hoisting. It can be used in two situations: a pair of ropes and a rope. The disadvantage is that it can only be carried out when the rope is not stressed. Sometimes it takes several times. to be levelled.
2 Inverted chain leveling method
This method is to connect the inverted chain in series in the hoisting belt, adjust the length of the binding rope, and make the heavy object level. When the force of the inverted chain is overloaded, the pulley and the inverted chain can be used as a running rope to achieve the purpose of adjusting the sling. It should be noted that the length of the rope should be moderate. If it is too long or too short, the reverse chain cannot be adjusted. It should be adjusted when the sling has been stressed but the weight is not off the ground. It should prevent a rope or reverse chain from being overloaded.
