The slewing cylinder is a key hydraulic component in Schwing concrete pumps, enabling the horizontal rotation (slewing) of the placing boom. This controlled movement allows operators to precisely direct concrete flow across a wide area. The category also includes essential accessories such as linkages, mounting hardware, hydraulic blocks, and seals that support installation and proper functioning of the cylinder.
Key Features
Heavy-Duty Hydraulic Actuation: Double-acting cylinder design ensures bidirectional movement with consistent torque output, allowing for smooth and powerful boom slewing.
High-Strength Materials: Cylinder bodies and related components are manufactured from heavy-duty steel to resist stress, fatigue, and environmental wear.
Precision-Controlled Movement: Engineered for smooth, responsive slewing to support accurate boom positioning in tight or high-reach job sites.
Optimized Sealing System: Integrated seals prevent hydraulic leakage under pressure and extend component service life.
Mounting Flexibility: Includes clevis, yoke, flange, or trunnion mount options tailored to fit the boom base and main frame of various Schwing pump models.
Support Accessories: Hydraulic manifolds, pivot pins, rod ends, wear plates, and bushings designed for secure and reliable integration with the cylinder.
Common Applications
Horizontal rotation of the placing boom for precise concrete delivery.
Controlled boom positioning during setup and continuous operation.
Boom movement synchronization with other pump functions in multi-axis operation.
Load management during pumping to prevent boom stress or misalignment.
