Putzmeister® Trunk System & Accessories Series for Concrete Pumps
Engineered for Reach, Precision, and Durability
The Trunk System & Accessories Series by Putzmeister® is the structural and hydraulic backbone of the concrete pump’s boom. Designed for powerful articulation, exceptional reach, and pinpoint concrete placement, this system is vital to job site performance. From high-rise pours to hard-to-reach footings, Putzmeister® ensures precision and safety with every boom movement.
🔧 Key Features & Benefits
Extended Reach & Job Site Access Articulating boom sections enable concrete placement across large areas and over obstacles, improving efficiency on complex pours.
High-Precision Delivery Accurately directs concrete flow to target zones, minimizing waste and maximizing coverage.
Rugged Construction Fabricated from high-strength steel to handle dynamic loads and resist wear from concrete pumping operations.
Hydraulic-Powered Movement Integrated hydraulic cylinders provide smooth, controlled articulation of boom sections for safe and accurate positioning.
Modular Boom Configurations Available in various lengths, section counts, and geometries to meet the demands of different job types and pump models.
Built-in Safety Features Includes design elements that prevent overextension, instability, and excessive wear, protecting operators and equipment alike.
Full Putzmeister® Compatibility Seamlessly integrates with Putzmeister® concrete pump chassis, control systems, and delivery mechanisms.
🧩 Component Overview (Based on Images)
🖼️ Component
🔍 Function
Boom Sections (Tubular Yellow Segments)
Form the articulating arms of the trunk system, designed for reach and strength.
Hydraulic Cylinders (with Bearings)
Drive the extension, retraction, and elevation of each boom section.
Pivot Joints & Hinges
Allow rotational movement between boom sections while supporting dynamic loads.
Wear Pads / Support Plates
Minimize friction and wear between moving parts and at resting points.
Boom Tip Hose Connection (Angled Piece)
The attachment point for the concrete delivery hose—often the final discharge.
Boom Rest or Support Bracket (Curved Part)
Supports the folded boom during transport or idle times.
Rotation Joint (Ring with Bolt Holes)
Enables horizontal slewing of the entire boom assembly for wide-range coverage.
🏗️ Trunk System Function in a Putzmeister® Concrete Pump
The trunk system enables precise and safe positioning of the concrete delivery hose by:
🛠️ Extending/Contracting Boom Segments Hydraulic actuation adjusts reach on the fly.
⬆️⬇️ Lifting/Lowering Boom Arms Controls elevation angle to target upper stories or ground-level areas.
🔄 Slewing the Boom A rotary joint allows horizontal movement for wide area coverage without repositioning the truck.
🪝 Carrying the Hose Provides structural support to guide the flow of concrete from hopper to pour point.
🛡️ Why Boom System Integrity is Crucial
✅ Productivity Delivers concrete where it’s needed—faster and more efficiently.
🔒 Operator Safety Precision control and integrated safeguards minimize the risk of structural failure or accidents.
🔧 Equipment Longevity Robust design reduces wear-and-tear, extending service life and cutting downtime.
🌐 Site Flexibility Adapts to the layout and elevation challenges of diverse job sites.
