Abstract: Anchors, clutches, and lifting systems are described herein that increase the size of a shear cone within a precast concrete panel without using multiple clutches and without increasing the complexity of the lift system. A shear cone is the volume within the panel that the anchor and clutch pull on when orienting and positioning the precast concrete panel. Anchors described herein encompass a larger volume of the panel in different ways to produce a larger shear cone. Similarly, the clutches described herein have features that allow a clutch to accommodate the improved anchors. As a result, the anchors, clutches, and lifting systems provide a larger shear cone in the panel to increase the load capacity of the lifting system and reduce the likelihood of failure.
