ECCENTRICITY CORRECTING DEVICE OF WIDTH DIRECTION POSITION OF SLAB

摘要

PURPOSE: A position of a crane is corrected by measuring eccentricity of a slab standing by on a roller table, and a gripping position by the eccentricity is controlled. CONSTITUTION: An eccentricity correcting device is provided to correct an eccentricity of width direction of a slab when picking up the slab on a roller table using a cross arm. A slab eccentricity detecting device is installed in both sides of the roller table to measure an eccentricity of the slab before gripping with a pickup crane. A gripping position measuring member is installed in a center beam connecting a forward and a backward cross arm. A crane position controlling member calculates the position of the pickup crane.
