Abstract

This utility model belongs to the field of hydraulic winch technology, specifically a marine hydraulic winch, including a fixed plate. A rotating shaft is fixedly installed in the center of the fixed plate. A groove is formed on the fixed plate and on the outer side of the rotating shaft. A ball bearing is fitted into the inner side of the groove. A rotating disk is fixedly installed on the top of the rotating shaft. A bearing is provided on the fixed plate and on the outer side of the rotating disk. A handle connecting rod is fixedly installed on the bearing, and a second gear is fixedly installed on the handle connecting rod. The bearing on the fixed plate and on the outer side of the rotating disk supports the handle connecting rod, allowing it to rotate smoothly on the fixed plate. The handle connecting rod fixed on the bearing drives the second gear to rotate, which in turn drives the rotating disk to rotate. This allows the hydraulic winch body to rotate flexibly during use, improving the efficiency of steel cable winding and unwinding.
