This hydraulic hood tilt cylinder serves as the power unit for cab tilting system. It outputs stable hydraulic thrust to lift and support the cab for engine inspection and maintenance. The cylinder adopts precision honed tube and high-performance sealing assembly, effectively preventing hydraulic oil leakage under frequent lifting operations. Its solid piston rod and reinforced joint structure resist impact and bending deformation. The surface anti-rust coating protects the cylinder from mud, rain and salt spray erosion in harsh road environments. Each cylinder undergoes pressure and load testing before delivery. It solves slow lifting, oil leakage and insufficient support issues, an essential replacement part for cab tilting system repair.
