Abstract: In order to exert a constant pull on a rope attached to a load and wound up on a winch by the motor of a hydrostatic transmission mounted on a floating boat moving up and down, a pressure responsive valve is actuated by a predetermined high pressure in the hydrostatic transmission when the boat and winch are raised, and relieves the pressure in a cylinder chamber of an hydraulic adjusting motor so that the volume of fluid displaced by the pump of the transmission is reduced, whereby the lifting movement is slowed down, and the pull on the rope maintained constant when the boat with the winch is raised by waves to a higher level.
