DBZ 112 P2 -15- ABSTRACT OF THE DISCLOSURE An apparatus for lifting precast concrete panels includes a lifting body having a forward portion adapted to engage in an anchor head, a latch yoke pivotally connected to a rearward end of the lifting body and including a safety latch cooperating with the forward portion of the lifting body to lock an anchor head to the forward portion, a release yoke pivotally attached to the lifting body for movement between locked and release positions and including a cam effective during movement of the release yoke to its release position to cause the latch yoke to pivot to a release position, and a lifting bail pivotally attached to the forward portion. The release yoke includes a safety pin block extending from a rearward portion thereof adjacent the rearward end of the latch yoke. The latch yoke and safety pin block include bores which are in registry with each other when the apparatus is oriented to a locked position. A safety pin is inserted into the bores and prevents relative pivotal movement between the latch yoke and release yoke, and is removable from the bore by a lanyard which is pulled by a worker.
