Tower Crane Lifting Cylinder

Tower Crane Lifting Cylinder is a heavy-duty hydraulic actuator specifically designed for construction machinery and tower crane systems. It is primarily used to control the lifting, lowering and precise positioning of heavy loads, ensuring safe and efficient operation in high-altitude construction projects.

Features:

The tower crane hydraulic cylinder engineered by Qingdao Micro Precision Machinery delivers superior performance for heavy-load handling, providing exceptional strength and reliability for construction lifting applications. As a robust lifting solution, its precision hydraulic control guarantees smooth and stable operation, while premium sealing components (such as Parker or equivalent) minimize friction and extend service life. Custom specifications including stroke length, mounting styles and pressure ratings are available to meet various project requirements.
