EXTRA-LONG HYDRAULIC JACK: This hydraulic jack has a capacity of 50T and a stroke of 12in/300mm, which is more effective than other products to increase the stroke, so that heavy objects can be lifted higher and more convenient to use. ZG3/8 JOINT JACK: Our ram hydraulic cylinders are designed to provide reliable support during operation. Electroplated piston for lifting without jamming, large tonnage of 100T/220462lb, sufficient stroke of 300 mm/12 in. (20/30T jacks fit CP-700 hand pumps, 50/100T jacks fit CP-700-2A hand pumps). HYDRAULIC JACK: This jack offers better pressure retention and greater stability than ordinary hydraulic jacks. In addition, the jack is designed with an electroplated piston rod with a smooth surface for smooth lifting and improved efficiency, while the top of the piston rod is designed with a groove to increase friction and prevent slippage. WIDE APPLICATION: This long jack is widely used in the installation and maintenance of large and medium-sized machinery and equipment in petroleum, electric power, metallurgy, steel, ships, bridges and other industries. MULTI-SECTION HYDRAULIC CYLINDER JACK: This hydraulic cylinder is designed with multiple sections, which is especially suitable for lifting and supporting work in limited space. Please note that the jack piston does not retract on its own after the pressure is released! You must use gravity to press the jack back in, this is not a quality issue., Manufacturer: DINGSHI
