A component employed in lifting operations, these rigid members serve to maintain separation between multiple sling legs. Acting as a structural element, they prevent compressive forces from acting on the load, ensuring stability during hoisting. For instance, when lifting a wide or irregularly shaped object, the use of this equipment allows the sling legs to remain vertical, distributing the load evenly and minimizing the risk of damage or instability.
The adoption of this method provides crucial advantages in terms of safety and load control. By preventing the inward pull of slings, they reduce stress on the load and lifting equipment, extending their lifespan. Historically, their use has evolved from simple wooden beams to sophisticated engineered structures fabricated from steel or aluminum, reflecting advancements in material science and lifting technology. These advancements contribute significantly to the improved safety and efficiency of lifting operations across various industries.
