The Vevor Hydraulic Top Link Cat. 2-2, with a working pressure range of 20/18 MPa, generates 4 tons (8818 lbs.) of pushing force and 2.5 tons (5511 lbs.) of pulling force without mechanical gears or levers. It features bidirectional check valves with locking blocks for enhanced sealing and precision control, ensuring minimal hydraulic oil backflow. Constructed from robust 45# steel and coated with corrosion-resistant paint, it ensures durability in harsh environments. The rotating piston rod allows for flexible installation on various tools, and the 1.0 in (Φ25.5 mm) connection hole diameter ensures compatibility with Cat. 2-2 tractors.
