A screw pin chain shackle is a type of shackle that features a removable pin or bolt that can be screwed in and out of the shackle body. This design allows for easy attachment and detachment of the shackle from lifting or rigging equipment.
Screw pin chain shackles are commonly used in various industries and applications, including lifting, rigging, towing, and general purpose use. They are available in a range of sizes and weight capacities to accommodate different loads and requirements.
When using a screw pin shackle, it is important to ensure that the pin is securely tightened before lifting or applying load.
Regular inspection and maintenance should also be conducted to check for any signs of wear, deformation, or damage that may compromise the shackle’s integrity.
THE MAIN COMPONENS OF A SCREW PIN SHACKLE
Body: The body of the shackle is typically U-shaped or bow-shaped, providing the main structure of the connection point.
Screw Pin: The screw pin is a threaded rod that passes through the ends of the shackle body.
It has a head or handle on one end for easy turning and a threaded portion on the other end that engages with the shackle body.
The screw pin can be tightened or loosened by rotating it, allowing for quick and secure connections.
