Custom hydraulic system consisting of (4) 150 ton 36 inch stroke pull cylinders that was designed and supplied \u00a0to launch crane onto a barge on the Elizabeth River. This crane was \u00a0to assist in the beginning of the Tunnel Construction, \u00a0the total distance the crane was launched was 150 ft . \u00a0the most disfficult challenge was keeping \u00a0all 4 cylinders within tolerance while siding it 36 inches at a time. Until it got i onto the barge. A 4 point synchronous manifold equipped with flow control valves made this possible , the crane safely launches onto the barge.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Our client safely and accurately slid the crane onto a barge using a 600 ton synchronous jacking system with four 150 ton pull-cylinders with a 36\u2033 stroke.\u00a0<\/p>\n

Precision controlled raising or lowering of a tower crane. Digitally controlled monitoring and recording of movement, maintaining levelness and reducing internal stress.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Our client used an 800 ton synchronous jacking system, comprising of four 200 ton 9ft stroke double-acting jacks and was able to raise and lower the tower safely into place.<\/p>\n

Using a 2000 ton synchronous, jacking system consisting of eight 250 ton 12 inch stroke double-acting cylinders our client was able to raise the crane 24 inches whilst maintaining a 1\/8\u2033 tolerance across all eight jacks.<\/p>\n

The old slew bearing was removed and replaced. The crane was then lowered back down maintaining the same 1\/8\u2033 tolerance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
