Threaded Combination Lifting Loop was specifically designed for inclined lifting forces up to 90 degrees. This makes it ideal to use when sockets are fixed into the sides of units to facilitate tilt up lifting when turning a panel from horizontal to the vertical plane.
Due to the use of high tensile steel components in the manufacturing process of the Combination Threaded Lifting Loops, it is imperative that welding of the lifting device and excessive heat sources are avoided.
See figure 27 and table 25 for specific dimensions.
**Use and Operation**
After visual inspection the Threaded Combination Lifting Loop should be threaded fully into the lifting socket. The loop should be threaded in until the base of the loop makes full contact with the concrete around its full perimeter. Check that the base of the lifting loop and the contact surface of the concrete are parallel with each other. If this criteria is not met, then damage to both the concrete and the lifting socket could occur.
