What is the maximum angle allowed between the lifting cable and vertical when using two lifting lugs?

The maximum angle allowed between the lifting cable and vertical when using two lifting lugs is 30 degrees. This specification is important because as the angle increases, the load on the lifting lugs changes significantly. At greater angles, the forces exerted on the lugs can become uneven, leading to potential stress and failure of the lifting hardware. Maintaining the cable within 30 degrees of vertical allows for a balanced distribution of forces, thus ensuring the safety and integrity of the load being lifted. This standard is often established in engineering practices to minimize risks associated with lifting and handling loads, ensuring safe operations in environments that utilize lifting equipment. Maintaining this limit ensures compliance with safety regulations and best practices in the industry.
