Abstract

1,216,418. Hydraulic climbing Jacks. BYGGFORBATTRING A.B. 1 March, 1968 [3 March, 1967], No. 10218/68. Heading B8J. A jacking system for lifting a load step-bystep comprises two similar hydraulic climbing jacks 40, 40<SP>1</SP>. A load (not shown) is attached to smooth rods 3, 3<SP>1</SP>. The jacks are operated by a pump 20 which may be manually or power driven. Balancing hydraulic jacks 80, 80<SP>1</SP> are interconnected by a pipeline 24 and function as compensating means to prevent or correct any imbalance of the load on the rods 3, 3<SP>1</SP> such as may be caused by variation of the actual stroke of a jack from its nominal valve. In operation, prior to starting up the pump 20 to pressurize cylinders 4, 4<SP>1</SP> of main jacks 1, 1<SP>1</SP>, the valves 11, 11<SP>1</SP> are opened to permit pressure transfer, cylinders 8, 8<SP>1</SP> of the balancing jacks 80, 80<SP>1</SP> being partly full of hydraulic fluid.
