A load-balancing device can be used to assist the lifting and lowering of heavy objects. In some examples, a load-balancing device includes a housing, a first movable pulley, a second movable pulley, a stationary pulley positioned between the first movable pulley and the second movable pulley, and a cable wound at least partially around the first movable pulley, the second movable pulley, and the stationary pulley. In operation, a pressurized control fluid may be introduced into a pressure chamber defined between the housing, the first movable pulley, and the second movable pulley. This can cause the first movable pulley and the second movable pulley to move away from the stationary pulley, withdrawing the cable into the housing and lifting a load attached to the cable.
