In one embodiment, an apparatus includes a hoisting system having a hoisting line, a sleeve positioned on the hoisting line, and an an- ti-two-block sensing device installed about the hoisting line so as to allow the hoisting line to move through the anti-two-block sensing device. The an- ti-two-block sensing device includes a detector positioned to detect a sleeve component when the sleeve is present within the anti- two-block sensing device. Additional systems, devices, and methods are also disclosed. 3 26 , 34 32 11 ir) GC © ei M ,-1 IN ,-1 © ei 14 36 28 30 O
