It seems like you're asking about anchor bolts, bow shackle safety factors, and G-2130 shackles. Here's some information on these topics:
Anchor bolts are commonly used in construction and structural engineering to secure objects to concrete. There are various types of anchor bolts, including wedge anchors, sleeve anchors, and concrete screws. Each type is designed for specific applications and load requirements. It's important to select the appropriate anchor bolt type based on factors such as the material being anchored, the load capacity, and the installation environment.
The safety factor of a bow shackle refers to the ratio of the breaking load to the working load limit (WLL). It is a critical consideration in ensuring the safe use of shackles in lifting and rigging operations. The safety factor is typically determined by dividing the breaking load by the WLL. For example, a shackle with a breaking load of 20 tons and a WLL of 5 tons would have a safety factor of 4. It's essential to adhere to recommended safety factors to ensure the reliability and safety of lifting operations.
The G-2130 shackle is a specific type of screw pin anchor shackle manufactured by Crosby, a well-known producer of rigging and lifting equipment. The G-2130 shackle is designed for use in applications that require a high-strength, dependable connection point. It is important to ensure that the G-2130 shackle is used within its rated load capacity and in accordance with safety guidelines to maintain safe lifting and rigging practices.
When using anchor bolts, shackles, or any lifting and rigging equipment, it's crucial to follow industry standards, manufacturer recommendations, and safety guidelines to ensure the safe and efficient operation of lifting and rigging activities. Additionally, consulting with industry professionals and suppliers can provide valuable insights into selecting the right equipment for specific applications.
