The pulley acts as part of the dynamic force equalization system that distributes loads evenly through the strap and prevents adverse force vectoring. Its unique design also allows dynamic loading of the cervical spine with stabilizing straps that detach if the correct angle of force is not maintained. This assures good technique and prevents axial loading during lifting.
