The Hydraulic Rock Block Jack, also known as a Quarry Peak Jack, is a specialized hydraulic lifting system developed for stone quarry operations. It is primarily used to move, lift, position, and control large rock blocks during extraction, helping operators perform heavy-duty tasks with greater safety and precision. <\/p>\n

Operating with a high-pressure hydraulic system, the jack delivers a smooth and controlled lifting force, making it suitable for demanding mining environments where reliability and accuracy are essential.Available with a lifting capacity from 500 to 1,000 tons and a working pressure of 1,000 bar, the equipment is manufactured in both electric and pneumatic versions. Its heavy-duty construction, high-pressure piston pump, and pressure control system ensure dependable performance and a long service life. <\/p>\n

This hydraulic jack is widely used for handling dimensional stone such as granite, marble, travertine, and limestone, where it assists in releasing and positioning stone blocks after cutting. It is also suitable for industrial lifting, heavy equipment installation, maintenance operations, and civil engineering projects. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>\n<\/div>\n
