1. Comprehensive Product Overview<\/h2>\n
\n
\n

The EPYY11112027 truck crane rear outrigger cylinder<\/strong> is a specialized vertical actuator integrated into the rear chassis stabilizers. Its primary function is to extend the outrigger pads to the ground, leveling the machine and transferring its weight to a stable footprint. This stabilization jack cylinder<\/strong> is the backbone of safe lifting, ensuring that the crane’s center of gravity remains secure even when working at maximum outreach.<\/p>\n

Built with a \u03a670mm bore and \u03a655mm rod, this model offers an exceptional strength-to-weight ratio. It serves as a high-performance aftermarket replacement for global mobile crane brands, featuring a 640mm installation distance and a reinforced mounting block design optimized for the dynamic vibrations of active job sites.<\/p>\n

    3. Structural Principles & CAD Blueprint<\/h2>\n
    \n
    \n

    The EPYY11112027 functions as a vertical double-acting hydraulic jack. Integrated into the rear stabilizer boxes, it uses system pressure to extend the outrigger beam pads downward. By establishing firm ground contact, it ensures that the chassis remains horizontal, providing the necessary leverage for the crane’s telescopic boom to function safely.<\/p>\n

    Hydraulic Performance:<\/strong> Supplying 20MPa to the \u03a670mm bore generates the stable force required to level medium-to-heavy mobile equipment. The thick \u03a655mm rod is specifically engineered to provide extreme columnar strength, preventing any risk of buckling when the cylinder is under full compression from the machine’s rear weight.<\/p>\n

    Blueprint Anatomy:<\/strong> The CAD drawing details a robust mounting block design at the cylinder base, which distributes load evenly into the outrigger beam. A specialized spherical rod end allows the outrigger pad to adapt to sloped or uneven ground, preventing destructive lateral forces on the internal seal matrix.<\/p>\n<\/div>\n

    Anti-Buckling \u03a655mm Rod<\/h3>\n

    The high-tensile 55mm rod is induction-hardened to provide unparalleled columnar strength, critical for preventing buckling under full vertical load.<\/p>\n<\/div>\n

    \n
    \u2699\ufe0f<\/div>\n

    Compact 24kg Integration<\/h3>\n

    The ultra-slender build minimizes rear-chassis weight, maintaining the machine’s center of gravity for safe road travel between jobsites.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

    5. Elite Structure and Material Craftsmanship<\/h2>\n
    \n
    \n

    Establishing stability for high-reach lifting requires uncompromised metallurgy. As an elite Heavy-Duty Outrigger Cylinder Manufacturer<\/strong>, we utilize ST52.3 (E355) high-yield strength seamless steel to ensure the EPYY11112027 outlasts the equipment it serves.<\/p>\n

    The \u03a670mm internal bore is roller-burnished to an absolute mirror finish of Ra 0.2\u00b5m. This minimizes dynamic friction during outrigger deployment, preventing thermal seal degradation even in dusty environments where abrasive grit is present.<\/p>\n
