Abstract: A regulator to limit the raising, pulling, or stretching load capacity of a lever type hoist to a predetermined maximum. The regulator is operably mounted between the drive input applied via an operating lever and the output drive on which a load is received and/or contained. An adjustably presettable braking friction applied between coaxially interfit components rotationally connects the input and output drives. In the event the input driving force exceeds the imposed braking friction, the hoist is rendered inoperable to raise, pull or stretch the load but continues operable to lower or release the load.
