What method is generally used for horizontal lifting of heavy objects? The correct binding method shall be adopted according to the characteristics of the heavy objects, and the heavy objects can be leveled by the following methods. 1. Rope moving leveling method 2. Chain block leveling method

1. The method of rope moving and leveling is to use the movement of the binding rope at the binding point or on the hook to change the position of the binding point or the length of the stressed rope strand to make the weight level. It is applicable to the horizontal lifting of slender heavy objects tied at two points. It can be used in two cases: pair rope and one rope. Disadvantages: It can only be carried out when the rope is not stressed, and sometimes it can only be leveled several times.

2. Chain fall leveling method The method of connecting chain fall in series with the binding rope, adjusting the length of the binding rope, and leveling the weight. There are one point, two points and multi-point adjustment. It can be carried out with load and adjusted accurately. When the chain block is overloaded, the pulley and chain block can be used as the running rope to adjust the binding rope. In practical work, there are many chain block adjustment methods for eccentric equipment.

Precautions: (1) The rope length should be moderate. If it is too long or too short, the chain fall cannot be adjusted. (2) When the binding rope has been stressed, but the weight is not off the ground, the adjustment should prevent overloading of a rope or chain block on the list.

2、 The double crane lifting method uses two lifting machines to lift the same weight, load and unload it or hoist it in place, which is called the double crane lifting method.

1. Construction conditions applicable to double crane lifting method

2. Participate in the load distribution of double crane lifting operation machinery

3. Influence of inclination during lifting on load distribution of lifting machinery involved in lifting

four Huai'an Crane Leasing Company Remind the main precautions in the double crane lifting construction

1. The construction conditions applicable to the double crane lifting method, and the weight of the load exceeds the rated lifting capacity of one crane.

2. The overall dimensions of the equipment are very large. Although the rated lifting capacity of a lifting machine can meet the needs, the hook height or lifting range is limited and it is not suitable to use a single crane for lifting.

3. Double crane lifting when the equipment is turned over, or the equipment is erected in place.
