[0018] Specialized tools for lifting large packages with connecting rods, such as Figure 2 and Figure 3 As shown, it includes a connecting rod lifting frame 1, a balance beam 2, and a counterweight; the connecting rod lifting frame 1 is fixed to one end of the balance beam 2, and the counterweight is connected to the other end of the balance beam 2; a T-shaped structure is formed between the connecting rod lifting frame 1 and the balance beam 2; a lifting lug 3 is provided at the top of the balance beam 2, which is the attachment point for the lifting tool, and its setting facilitates the connection of the lifting tool.
[0019] Two upper connecting rod rear lifting lugs 4 are provided at the bottom of the connecting rod lifting frame 1 along the longitudinal direction of the connecting rod lifting frame 1. The two upper connecting rod rear lifting lugs 4 are symmetrically arranged along the transverse center line of the connecting rod lifting frame 1. Two upper connecting rod front lifting lugs 5 are provided at the bottom of the connecting rod lifting frame 1 along the longitudinal direction of the connecting rod lifting frame 1. The two upper connecting rod front lifting lugs 5 are symmetrically arranged along the transverse center line of the connecting rod lifting frame 1. In the transverse direction, the upper connecting rod front lifting lugs 5 are located in front of the upper connecting rod rear lifting lugs 4.
[0020] Among them, the horizontal direction is Figure 2 The extension direction of the balance beam 2 in this state is also... Figure 2 The width direction of the central connecting rod lifting frame 1; the longitudinal direction is perpendicular to both the transverse and vertical directions, and is also... Figure 2 The length direction of the middle connecting rod hoisting frame 1.
[0021] The two upper connecting rod rear lifting lugs 4 at the bottom of the connecting rod lifting frame 1 are used to connect with the two rear lifting rings 901 of the connecting section of the upper connecting rod 9 of the large package, for lifting the upper connecting rod 9 of the large package.
