PURPOSE: A rotation system of hydraulic accessories is provided to increase rotation torque necessary for power supply by changing the deceleration ratio of a motor and to simplify the assembling process of each component by improving the structure. CONSTITUTION: A rotation system of hydraulic accessories includes: a torque converter engaged with a driving shaft of a hydraulic motor(150), having at least two and more multi-step gears; a rotator(420) interlocking to rotation of the torque converter, mounted inside a housing(100) rotatively, having a path for supplying hydraulic pressure to nippers(200); and a connector combined to the lower end of the rotator and installed to remove a body(300) in one direction. When the hydraulic motor is operated, a gear of the driving shaft rotates a first gear unit of the torque converter. A second gear unit integral with the first gear unit is rotated to interlock the rotator. Then, the body joined with the connector is rotated. The nippers are laid on the desired working position, and compressed oil is supplied to a hydraulic cylinder(210). Thereby, the hydraulic cylinder is operated. The rotation system of hydraulic accessories transfers power necessary for rotation by changing the torque conversion ratio of a motor. In addition, the rotation system obtains excellent assembling and disassembling work efficiency by improving the structure of the connector.
