Product Description Product DescriptionCore jack is a kind of hydraulic lifting equipment, mainly used to lift heavy objects. It is composed of hydraulic pump, oil cylinder, piston rod and base and other main components. When used, hydraulic oil is injected into the cylinder through a manual pump or an electric pump, and the piston rod rises under the action of oil pressure, so as to achieve the purpose of lifting heavy objects. The core jack has the characteristics of compact structure, easy operation, large bearing capacity, etc., and is widely used in construction, bridge, ship, machinery manufacturing and other industries. During use, it should be ensured that the jack is placed smoothly and overloaded to avoid use to ensure safe operation.

Finally, the oil nozzle of the tension cylinder and the top pressure cylinder return oil at the same time, and the top pressure piston returns to reset under the action of the spring force.In order to ensure the accuracy of tension, post tension jack should be matched with oil pump, pressure gauge and external high pressure hose to calibrate "oil pressure value - output force". In the calibration, the active working state of the jack shall prevail, and the classification shall be recorded. The average value of the three measurements shall be taken, and the chart shall be made as the basis for the tension. Installation Instructions1. Before using the core jack, check whether the components are in good condition, especially the wearing parts such as piston rod, cylinder and seal ring, to ensure that they are in good condition.2. During use, ensure that the jack is placed smoothly and avoid tilting or shaking to prevent accidents.3. Avoid overload. The core jack has a certain bearing capacity, which may cause equipment damage or safety accidents.4. When using the core jack, ensure that the operator has the appropriate skills and knowledge to avoid equipment damage or personnel injury caused by misoperation.5. After a long time of use, the quality and quantity of hydraulic oil should be checked, and the hydraulic oil should be replaced or supplemented in time to ensure the normal operation of the equipment.6. When storing the core jack, it should be placed in a dry, ventilated, non-corrosive gas environment to avoid moisture, heat or corrosion.Company ProfilePackaging & ShippingFAQ Q1: Warranty terms of your machine?A1: One-year warranty for the machine and technical support according to your needs.Q2: Will you provide some spare parts for the machines?A2: Yes, of course.Q3: What about the voltage of products?
