Hole jacks are used for tensile work rather than lifting. Perforated cylinders, which are especially used as bolt testers, have a very intensive use in the construction industry. Perforated cylinders have different bore diameters according to their tonnage. Jacks with a hole diameter of 21-81mm are selected according to the tensile-tensile load specified in the project. Hollow cylinders with single-acting and spring-return hydraulic system can operate both horizontally and in reverse. It offers faster operation and is easier to use than the old type load return jacks. In short, NSH series perforated hydraulic jacks are ideal for iron ore, bolt and stud pulling-tensioning operations. Perforated cylinders, manufactured using crack-controlled 4140 steel and the highest quality felts, have a 2-year warranty.
