The Schwing distributor gearbox is a critical element in concrete pumps equipped with placing booms. It ensures the precise and reliable transmission of hydraulic power to various boom functions—such as rotation, luffing, and extension/retraction of individual sections. Together with its associated accessories (ACCS), the gearbox allows for smooth boom operation and accurate concrete placement in demanding construction environments.
Key Features
Robust Housing Made from high-strength cast iron or steel, offering durability and protection for internal components in rugged operating conditions.
Precision-Engineered Gearing Utilizes spur, helical, or worm gears—hardened and finely machined—for efficient power transmission and extended lifespan.
Multiple Output Shafts Designed to drive multiple hydraulic motors or actuators, supporting simultaneous or sequential boom movements.
Sealed Design Equipped with high-performance sealing systems to prevent leaks and block contamination, ensuring consistent operation.
Mounting Provisions Includes standardized bolt patterns and flanges for secure attachment to boom assemblies.
Integrated Components May feature oil level indicators, fill/drain plugs, and pressure relief valves for ease of use and maintenance.
Potential Applications
Power transmission to boom rotation mechanisms.
Driving luffing cylinders for vertical articulation of boom arms.
Operating telescopic sections for extension and retraction.
Coordinating complex boom movements for precise concrete placement.
Accessories (Examples Based on Image)
Actual components may vary by gearbox model but commonly include:
Gear Housings Heavy-duty casings (some split-type) to house and protect internal gear sets.
Spur Gears Straight-tooth gears for transferring power between parallel shafts; various sizes for tailored torque output.
Shafts Machined with splines or keyways for proper gear fitting and power transfer.
Couplings/Flanges To connect gearbox outputs to hydraulic motors or auxiliary mechanisms.
Seals and O-Rings For maintaining internal lubrication and preventing hydraulic fluid leaks.
Mounting Brackets/Plates Custom-shaped for firm and stable installation on the boom chassis.
Other Components May include bearings, shims, keys, and retaining rings essential for gearbox assembly and maintenance.
Note
For accurate identification and part ordering, please:
Determine the exact Schwing concrete pump and placing boom model.
Reference the Schwing parts catalog or consult a certified supplier.
Provide the gearbox or component part number whenever possible to avoid mismatches.
