Hydraulic Jacks are useful equipments for use in stone quarries. Hydraulic Jacks are basically used for shifting and tilting boulders and 'banks' in quarries. After the initial drilling or cutting is executed on the stone face, the cut 'banks' are upturned by the Hydraulic Jacks. Basically, Hydraulic Jacks are designed with oleo dynamic system for applying thrust on the boulder for upturning. The Hydraulic Jack pistons move forward upon the application of hydraulic pressure and push the boulder. Hydraulic Jacks are manufactured in different sizes and capacities depending upon the load requirement. Multiple Jack Hammers are also used simultaneously in large 'banks'. The lengths of the pistons of the Hydraulic Jacks also differ depending upon the displacement required.
