That is one reason we have Hand Chain Hoists such as the hydraulic hoists invented by lord Armstrong. When lifting a person, the forces required to move them may not move in a straight up or down direction, or side to side, there could be a combination of the both or even rotation forces, all of which will have an impact on a handler’s muscular and skeletal frame.https://www.baotgroup.com/hand....-hoist/hand-chain-ho
