Twin-Path® Adjustable Bridle Slings

Twin-Path® Adjustable Bridle (TPXA with K-Spec® or TPA with polyester):

The Twin-Path® Adjustable Bridle is a tool to find the center of gravity (COG). When the load is lifted, the bridle moves over the COG to balance and level the object. This tool was developed in conjunction with riggers in the field for lifting objects with uneven geometric proportions or off-center balance points.

The Twin-Path® Adjustable Bridle (TPXA with K-Spec® fiber core yarn or TPA with polyester core yarn) is a two-leg bridle made with a Twin-Path® roundsling and an adjustable bridle ring. The sling features a double leg for the heavy side of the load and a single leg on the opposite side. When tension is applied to the Twin-Path® Adjustable Bridle, it self-adjusts until the lifting point is over the center of gravity (COG). This allows the two legs to be adjusted for a level lift without the need for custom slings or hardware. .

The Twin-Path® Adjustable Bridle has a double leg for the heavy side of the load and a single leg on the lighter side.

If the lifting points are an equal distance from the center of gravity, then the Twin-Path® Adjustable Bridle can be hooked up with the double or single leg on either lifting point.

If the lifting points are an equal distance on either side of the center of gravity, then the double leg should be attached to the higher lifting point.

If one of the lifting points is closer to the center of gravity, then attach the double leg to this lifting point. It will have the highest weight concentration. If the Twin-Path® Adjustable Bridle is attached so that the single leg is nearest the center of gravity, the lift cannot be made.

The Twin-Path® Adjustable Bridle should be used where the double leg horizontal angle is greater than 45 degrees. Always connect above the center of gravity. If connections are made below the center of gravity, then the load may turn while lifted.
