Product introduction
Electric hydraulic multi-lobed grab & double-lobed grab is a kind of working device which provides power to hydraulic cylinder through hydraulic power source, thus driving the opening and closing of left and right two buckets or multiple jaw plates to grab and unload bulk materials. Hydraulic grab belongs to hydraulic structural parts, and hydraulic cylinder is the most important driving component. We use international first-line brand hydraulic components for long service life.
Electric hydraulic grab is characterized by grasping big force, high automation, which can work in the bad environment for a long time. It is an ideal loading and unloading tool for bulk ore, scrap steel, garbage, straw, slag and other materials. It is mainly used in iron and steel, mines, coal mine, ports, mineral waste residue and other industries.
