Cylinder clamping process in steel cylinder hoisting

The invention provides a cylinder clamping process in hoisting of a steel cylinder, which comprises the following steps of: hoisting a vibratory hammer system to a construction site; the transport ship is parked, and the crane ship moves to the position near the transport ship through the anchor cable of the crane ship; the crane ship translates to enable the hammer set to enter the position over the top of the steel cylinder, an anchor cable of the crane ship is tightened, hooks on the crane ship are loosened till the steel lifting cylinder enters a hydraulic clamp guide groove, then the vibratory hammers are adjusted, and clamps in the two vibratory hammers symmetrically arranged according to the preset positions are tightly attached to a positioning steel plate preset on the steel cylinder; the number of the vibratory hammers is at least 12, and the 12 vibratory hammers ascend and descend synchronously and drive the clamps on the vibratory hammers to conduct high-altitude synchronous clamping at the same h
