Product Overview
The Load-Bearing Lifting Lug is a critical lifting and connection component used in cranes, construction machinery, mining equipment, pressure vessels, steel structures, wind power equipment, and large industrial systems.
It is used for lifting, transportation, installation, positioning, and maintenance operations. Connected with wire ropes, shackles, lifting hooks, and spreader beams, it enables safe hoisting and load transfer of heavy equipment.
As a core load-bearing element in lifting systems, the lifting lug is subjected to static loads, impact loads, and cyclic fatigue loads. Its structural strength and manufacturing quality directly affect the safety of the entire lifting operation.
With over 40 years of large-scale steel casting experience, Sangroove (Jiangsu) Machinery Co., Ltd. specializes in manufacturing lifting lugs, rigging lugs, equipment lifting points, and heavy-duty connection components for global OEM customers.
