Abstract
Abstract An anti-pounding device is provided to prevent the relative movement generated by waves to be transmitted to a tool. A system of pulleys is arranged on a carriage that is fixed to a guide path. A power winch is connected through a pulley to the carriage and accordingly, to a suspended tool to eliminate the relative movement of the boat. The arrangement of pulleys with a movable support can be connected to a tower or crane in a similar fashion with a compensation bar.
