Versabar Deck Raising System
The systems used to raise the two eight leg platforms utilized thirty-two synchronously controlled, 260-ton hydraulic cylinders to lift the platforms fourteen feet each. The cylinders pin into lower padeyes welded to the existing legs and upper padeyes integral to the split extension sleeve. The 40 1/2 inch diameter, 1 1/2 inch wall extension sleeves capture the legs during the final leg cuts and with the rub rails, limit lateral movement during raising to 1/4 inch. The legs are cut between two bushings installed near the top of the legs. Prior to the lift, the top of the extension sleeve is welded to the upper bushing, and after rising, the bottom of the extension sleeve is welded to the lower bushing. A twelve inch diameter, 1-3/4 inch wall pin inserts into the leg to provide a storm safe condition at all times except when removed to raise the platforms.
