The invention discloses a control method and control system of hydraulic bolt type lifting equipment and belongs to the field of lifting platforms. The control method comprises the steps that when all upper bolts are inserted into corresponding bolt holes, lower bolts are controlled to be pulled out of bolt holes; after all the lower bolts are pulled out of the corresponding bolt holes, piston rods of lifting oil cylinders are controlled to stretch; and the lower bolts are controlled to be inserted into the corresponding bolt holes. By monitoring the stretching-out lengths of the piston rods of the lifting oil cylinders and whether the lower bolts are inserted into the corresponding bolt holes in the hydraulic bolt type lifting equipment, when the hydraulic bolt type lifting equipment is controlled to fall, if it is detected that the lower bolts located between every two adjacent lifting oil cylinders are not completely inserted into the corresponding bolt holes and the stretching-out lengths of the piston rods of every two adjacent oil cylinders do not meet the inequation (please see the specification for the inequation), movement of the lifting oil cylinders and the lower bolts is stopped, so that the situation that the lower bolts and the bolt holes are damaged when part of the lower bolts cannot be inserted into or are not completely inserted into the corresponding bolt holes is avoided.
