✿ Vertical hydraulic jack: safety valve design, thickening stability, flexible lifting and easy operation.
✿ The five major advantages of welding jacks are: integrated welding process for oil leakage prevention, large lifting range of double section pistons, safer safety valve for overloading, easy operation for women, and portability. The product is compact and easy to carry.
✿ Spliceable remote rod saves time and effort: convenient storage, extended pressure rod, and more labor-saving car ordering.
✿ Flexible height adjustment, with free screw height at both ends: the lifting height varies depending on the car style; A section of spiral rod can freely adjust the height; Two stage piston rod pump type height adjustment.
✿ Product details: The piston rod is polished for aesthetic and anti-corrosion treatment, and the adjustment screw is made of excellent steel forging processing. The pressure rod can be connected to save time and effort, and the piston rubber oil plug has a high sealing degree.
♦ Product parameters: ▪ Approved load capacity: 3T ▪ Minimum height: 175mm ▪ Lifting height: 100mm ▪ Adjusting height: 60mm ▪ Maximum height: 335mm ▪ Product material: seamless steel ♦ Precautions: ▪ Before using the jack, be sure to read and understand all the contents of the manual ▪ Overloading the use of jacks is strictly prohibited ▪ The safety valve cannot be adjusted by oneself ▪ Before use, it is necessary to confirm that the support surface is a horizontal hard surface, otherwise it may be dangerous ▪ It can only be used for lifting, and matching jack brackets must be used to support the work object during operation ▪ Overloading is strictly prohibited, and it is not allowed to tilt and lift the working object, otherwise it may cause danger and damage the jack ▪ This machine uses oil as the medium and must be properly maintained to avoid clogging or oil leakage, which may affect the efficiency of use ▪ It cannot be used in places with acid, alkali or corrosive gases ♦ Oil injection method: Place the jack down with the plug facing upwards, open the plug, and then inject liquid oil. The amount of oil injection is determined by standing the jack upright, with the oil level just flush with the oil plug. When using N15 mechanical oil (GB44384) within the temperature range of 5 ℃± 45 ℃, synthetic spindle oil (GB44264) is used between 5 ℃ and 20 ℃.
