Features

• Jack Parameters---Tonnage: 10T | Stroke: 4/100mm | Self height: 6.14/156mm | Outer diameter: 2.48/63mm | Internal diameter:1.5/38mm | Weight:7.7lbs/3.5kg | Effective area: 2.46sq.in./15.89cm | Used with Pump: CP-180 | Connector: ZG3/8 male connector
• Longer 4 inch Stroke for More Reach---This hydraulic jack features a 4 - inch stroke. The extended stroke allows for greater height adjustment, making it more versatile in various heavy - duty lifting tasks. Whether you're working on industrial machinery, construction equipment, or other large - scale apparatus, this extra reach can be a real advantage. The hydraulic cylinder inside ensures smooth operation during the extension and retraction of the stroke.
• Smooth Lacquered Surface and Dust-Resistant Cover---The hydraulic ram cylinder features a smooth lacquered surface that not only gives it a sleek appearance but also provides good rust - resistance. Constructed from heavy - duty metal, this hydraulic cylinder jack is built to last. Additionally, it comes with a dust - resistant cover, ensuring that internal components remain clean and in optimal working condition for an extended period.
• Automatic Piston Retraction---Once the pressure is released, the piston of this hydraulic cylinder automatically retracts without the need for external force. This convenient feature simplifies the operation process. After using the hydraulic jack to lift heavy objects, you don't have to manually push the piston back. It's designed with a high - quality hydraulic ram system that enables this seamless retraction, providing users with a hassle - free experience.
• Multi - Angle Usage---This hydraulic ram can be used at multiple angles. Whether it's in a horizontal, vertical, or inverted position, it functions effectively. Its design allows for flexible use in different working environments. The smooth piston, a key part of the hydraulic cylinder, ensures smooth lifting regardless of the angle of use. Plus, its surface is treated to resist rust, maintaining its performance over time.
