hydraulic motor control and anti sway control system of gantry cranes in container.

摘要

in the field of container cranes in the following issue is: when the cart is du00c9place, which is suspended on cables under mechanical pru00c9hension swinging in the direction of travel.the systems used to reduce the swing of two disadvantages show: on the one hand, the high number of elements for the transmission of power, which means problems of maintenance; and, on the other hand, the separation of functions, namely, transfer the movement and the reduction of speed.the present invention relates to hydraulic drive motors for independent, autonomous, and to obtain a kinematic chain, and power transmission is simple, robust, reliable and easy maintenance, providing a solution to the problem. in addition, these motors are the two main functions: the production of movement, and the reduction of speed.by means of pressure limiting devices, the pressure peaks during the swing bearing motors are used. the system for controlling the pressure of the engine and thus the movement of swing.
