Product Description
This heavy-duty Luffing Cylinder is purpose-built for crane boom angle adjustment, serving as the primary force component that
directly controls the boom’s luffing motion. Rated for a working pressure range of 20-28MPa, it is constructed with a high-grade
27SiMn steel cylinder barrel, known for its exceptional strength, toughness, and resistance to high pressure and impact. The piston
rod is made of 42CrMo steel, precision-machined and treated with wear-resistant chrome plating, ensuring long-term durability
under heavy loads and continuous reciprocating motion. Unlike general-purpose hydraulic cylinders, this luffing cylinder is
engineered to meet the strict safety requirements of crane operations. It features precision sealing systems to eliminate internal
leakage under pressure holding, ensuring stable boom positioning even during long-duration lifting tasks. The design incorporates
advanced anti-eccentric load technology, effectively reducing side-force damage and extending service life. It is widely used in
mobile cranes, truck cranes, and tower cranes, providing reliable and smooth luffing performance to support high-altitude and
heavy-load lifting work. OEM and custom specifications are available to match various crane models, ensuring a perfect fit and
optimal performance.
