A screw pin bow shackle is a type of shackle commonly used in lifting and rigging applications. It consists of a U-shaped metal body with a threaded pin or bolt that screws into the body to secure the shackle. The U-shaped body has a bow or curved shape, which provides additional clearance and flexibility when connecting various lifting or rigging components.
The screw pin bow shackle is designed to provide a secure connection point for attaching slings, ropes, chains, or other lifting devices. It can be used in various industries such as construction, maritime, towing, and agriculture. The threaded pin or bolt of the shackle is tightened by hand or with the help of a wrench, ensuring a tight and reliable connection.
When using a screw pin bow shackle, it's essential to ensure that the pin is properly tightened before putting any load on the shackle. Regular inspections and maintenance should be conducted to check for signs of wear, deformation, or damage that may compromise the shackle's strength.
It's important to note that the working load limit (WLL) of a screw pin bow shackle should never be exceeded. The WLL indicates the maximum weight that the shackle can safely handle under normal working conditions. Using a shackle with a WLL that is too low for the intended load can lead to accidents, injuries, or equipment failure. Always refer to the manufacturer's guidelines and industry standards when selecting and using a screw pin bow shackle.
