摘要
The method involves detecting (6,7) the working pressure in the working circuit of each hydraulic motor (4,5) during the initiation of the closing movement and controlling it via a controller so that the same working pressure exists in both working circuits at the end of the gripper closing process. The arrangement has a sensor in the hydraulic line leading to each sensor. Independent claims are also included for the following: an arrangement for pressure equalization in hydraulic motors for driving the lifting and gripper closing cables of a cable crane.
