NOTE: Be advised that when rope blocks are used, the load imposed on the supporting structure is increased by the value of the hoisting effort, as well as on the equipment that is used to connect the top hook or eye of the pulley blocks to the structure. There must be a deal of care taken to ensure that the structure, along with all the hook equipment is of adequate capacity.
