[0001] The utility model relates to the technical field of wharf construction equipment, and particularly relates to a lifting balance device for precast beam and slab of wharf. Background Art

[0002] The lifting balance device for precast beam and slab of wharf is a key device to ensure the stability and safety of precast beam and slab during lifting.

[0003] The lifting balance device for precast beam and slab usually includes a balance beam, sling, hook and related connecting and fixing components. These devices work together to ensure that the precast beam and slab remain horizontal and stable during lifting and transportation, and avoid damage or safety accidents caused by imbalance or shaking.

[0004] In the lifting operation of precast beam and slab of wharf, it is often necessary to deal with the lifting requirements of beam and slab with various specifications and significant length differences. However, the lifting balance devices provided by the current technology center generally adopt a fixed-size design. When facing longer beam and slab, it often requires operators to replace the adapted balance device, which undoubtedly delays the lifting process to a certain extent and reduces the overall operation efficiency. Therefore, a lifting balance device for precast beam and slab of wharf is proposed. Summary of the Utility Model
