Method and arrangement for influencing the gripper filling volume in hoists with twin-motor gripper hoists

摘要

The invention relates to a method for influencing the Greiferfüllvolumens in hoists with Zweimotorengreiferhubwerken (locking mechanism and holding work), a corresponding system for data processing for carrying out the method and a machine on which such a program is stored. The aim is a solution that provides a limitation of the capacity of a designed for full load gripper solely by control engineering measures. For this purpose, it is proposed that in a closing operation of the gripper for a crane operation with reduced filling volume of the gripper an adjustable limit of the time required for holding the gripper is set, which is higher than the moment that would be necessary only for the taut holding of the tethers.
