The cross lifting beam is a force-balanced lifting tool with a cross structure design, specially used for the stable lifting of large regular square, rectangular and circular components, widely applied in mechanical assembly, large mold lifting, engineering component installation and special equipment transportation scenarios. Welded with high-strength alloy steel, its cross symmetrical structure bears balanced force and realizes four-point synchronous lifting, perfectly solving the problems of easy tilting, imbalance and uneven stress in single-point and two-point lifting, greatly improving the stability and accuracy of large regular workpiece lifting. The cross structure can effectively expand the lifting stress range, disperse heavy load pressure, avoid deformation damage caused by local stress concentration of workpieces, and fully protect the structural integrity of workpieces. With an accurately centered central lifting point and uniform surrounding lifting points, it features accurate positioning and stable lifting, which can effectively control the workpiece lifting posture and eliminate shaking, rotation and offset, meeting the needs of high-precision assembly operations. Having passed non-destructive testing and heavy-load pressure testing, it has a stable structure, accurate load-bearing and a safety factor far exceeding the industry standard, adapting to the lifting operation of large workpieces of different tonnages. With a simple and firm overall structure, reasonable self-weight and convenient installation, it can be matched with various cranes with strong versatility. The surface anti-corrosion and rust-proof treatment adapts to various indoor and outdoor working conditions, with wear resistance and fatigue resistance, enabling long-term high-frequency stable operation. It is the core equipment for high-precision and high-safety lifting of large regular workpieces.
