According to the actual application of the hydraulic automatic grab beam in water conservancy and hydropower projects,the alignment principle and process of the hydraulic automatic grab beam is analyzed. To solve the defects of alignment design in the traditional automatic hydraulic grab beam,a new alignment structure based on " flexible control of lowering speed" is proposed. The " process control" is put forward to realize the alignment between the automatic hydraulic grab beam and the lug of gate. The new structure can improve the alignment device of the traditional automatic hydraulic grab,which could ensure the alignment accuracy and also protect the safety of gate and the automatic grab beam.
