The Zoomlion ZLJ5410THB 52-meter concrete pump truck, mounted on a Mercedes-Benz chassis, illustrates how a five-axle boom package can combine long reach with urban maneuverability. Its active boom control system is designed to reduce vibration during placing operations, a factor that directly affects jobsite safety and delivery accuracy. The model also offers a useful case study in how used concrete pumps should be inspected, valued and supported across markets.
The ZLJ5410THB is a 52-meter boom pump built on a compact five-axle chassis. The layout allows the unit to maintain a long working radius while remaining practical for city construction sites, where road access and setup space are often constrained. Its boom uses a five-section RZ folding configuration, with a vertical reach of 52 meters and a horizontal reach of 51 meters.
The truck’s core technical feature is Active Boom Control, or ABC, which applies active vibration damping across boom positions. According to the manufacturer’s specification, the system can reduce boom vibration during operation by up to 50 percent, improving stability and safety when concrete is being placed at height or over distance. The pump is rated for a maximum concrete output of 120/70 m3/h and a maximum outlet pressure of 12/10 MPa, with a 365 kW engine.

When evaluating a used concrete pump, brand and model are only starting points. Maintenance records and the condition of core components are more important. A 2013-built ZLJ5410THB with 6,000 hours, for example, represents moderate use. Inspectors should focus on the following areas:
The used heavy-equipment trade is not merely a transaction in machines; it is also a transfer of technical know-how. Specialist suppliers that employ experienced technicians from major manufacturers can operate repair workshops and parts warehouses, giving buyers access to structured refurbishment programs and after-sales support.
That capability is particularly relevant in Southeast Asia, the Middle East and Latin America, where equipment buyers often need documented service histories, reliable parts availability and clear inspection standards before committing capital. For aging pump trucks, the quality of that support can matter as much as the original specifications.
