A concrete pump truck is a high-efficiency construction machine that integrates concrete transportation and pouring functions. It is widely used in construction fields such as buildings, bridges, and tunnels. Through its onboard pumping system, it delivers concrete to designated locations via the boom pipeline, significantly improving construction efficiency and precision. Below is a detailed introduction and typical technical parameters:

Main Components of a Concrete Pump Truck
- Chassis: Supports the entire vehicle and provides power and mobility (e.g., brands like Mercedes-Benz, Volvo, and Isuzu).
- Pumping System:
– Hydraulic Pump: Drives concrete delivery.
– Delivery Cylinder: Pushes the concrete.
– S-Valve (Distribution Valve): Switches the flow direction of concrete to ensure continuous pumping.
- Boom System: Composed of multi-section folding booms (3-5 sections) and hydraulic cylinders, allowing flexible extension (up to 100+ meters).
- Control System: Intelligent remote operation with real-time monitoring of pumping pressure, speed, and other parameters.
- Hopper and Pipeline: Receives concrete and delivers it to the end of the boom.
Core Features
- High-Efficiency Pumping: Capacity ranges from 30 m³/h to 200 m³/h, adapting to various project needs.
- Flexible Pouring: The boom can rotate 360°, covering a wide range and reducing manual pipe setup.
- Adaptive Technology: Intelligently adjusts pumping pressure to prevent pipe blockages.
- Eco-Friendly & Energy-Saving: Complies with China VI emission standards, with some models supporting electric drive.
Typical Technical Parameters
Max Pumping Height：30m-101m (common: 37m, 56m, 72m)
Max Pumping Capacity：30-200 m³/h (reduces under high pressure)
Boom Sections：3-6 folding sections
Boom Vertical Depth：20-90m (complements horizontal reach)
Delivery Cylinder Diameter：180-260mm (affects pressure & efficiency)
Chassis Engine Power：200-500kW (e.g., Mercedes OM470, ~400 HP)
Hydraulic System Pressure：30-35MPa (higher for high-pressure pumping)
Hopper Capacity：0.6-1.2 m³
Total Weight：30-70 tons (heavier for long-boom models)
Application Scenarios
High-Rise Buildings: Relies on long-boom pump trucks (60m+) for efficient pouring.
Municipal Engineerin: Medium/small pump trucks (30-50m boom) for flexible use in confined spaces.
Bridges & Tunnels: Requires high-pressure pumping to prevent concrete segregation.
Key Considerations for Selection
- Boom Length: Choose based on building height (recommended: 1.2x coverage height + horizontal distance).
- Pumping Pressure: ≥35MPa for high-rise/long-distance delivery.
- Chassis Adaptability: Short-wheelbase chassis for tight spaces.
- Smart Features: Such as blockage warnings and automatic boom obstacle avoidance.
