TL;DR
A rigging block is the heavy-duty arborist pulley attached to a tree with a rope or whoopie sling that redirects the lowering line during dismantling, letting cut limbs and trunk sections swing and descend under the friction control of a ground device. Unlike climbing pulleys, these blocks are built for the shock loads of falling wood, with working load limits chosen against forces that can multiply the piece's weight several times when it snaps tight.
