Product Description of Zoomlion Concrete Pump Truck

I. Product Introduction

II. Main Features

1. Efficient Pumping System: With a maximum theoretical conveying capacity of 180 m³/h and a maximum pumping pressure of 11 MPa, it can quickly push concrete with different slumps, meeting the needs of large - scale continuous pouring and reducing construction interruptions.
2. Flexible Placing Boom: With a maximum placing height of 63 m and a maximum placing radius of 58 m, the multi - section boom moves in coordination. Through intelligent control, it achieves precise positioning, suitable for complex pouring points in high - rise buildings and large - span venues.
3. Reliable Chassis Configuration: The Scania 5P 450 10x4 chassis and the DC13 143 engine output a strong power of 331 kW/1900 r/min, ensuring the mobility of the whole vehicle during transfer and the stability during operation, and adapting to various road conditions in urban and rural areas.
4. Intelligent Control and Maintenance: It integrates an intelligent control system, which can monitor the equipment status in real - time, with fault diagnosis and early - warning functions; the remote operation and maintenance module can assist after - sales service to respond quickly and reduce downtime.

III. Application Scenarios

1. Super High - rise Buildings: Relying on the large placing range, it can efficiently complete the vertical conveying of concrete for core tubes, curtain walls and other parts, covering the construction of buildings over 100 meters.
2. Bridge Cluster Projects: Suitable for the pouring of bridge piers, abutments and beam bodies, precise placing helps in the construction of curved beams and special - shaped piers, improving the quality of bridge construction.
3. Industrial Plant Construction: It meets the needs of continuous pouring of large - area workshop floors and equipment foundations, ensuring the flatness and strength of construction.
4. Municipal Pipe Gallery/Tunnels: In narrow operation spaces, the boom can be flexibly adjusted to complete the concrete conveying for the side walls of pipe galleries and the invert of tunnels.

IV. Technical Specifications

V. Common Problems

1. Boom Movement Hysteresis/Jamming
   • Causes: Hydraulic oil contamination (impurities blocking the valve group), aging and leakage of cylinder seals, and signal interference of the control system.
   • Solutions: Replace with clean hydraulic oil and clean the oil circuit; check the cylinder seals and replace if necessary; restart/calibrate the intelligent control system and check for signal source interference.
2. Sudden Drop in Pumping Pressure
   • Causes: Concrete segregation (aggregate accumulation blocking the pipe), large wear gap of the pumping piston, and failure of the main valve group seal.
   • Solutions: Clean the conveying pipeline and adjust the concrete mix ratio; measure the piston gap and replace if it exceeds the limit; overhaul the main valve group seal to restore pressure stability.
3. Abnormal Noise During Transfer
   • Causes: Loose chassis suspension bolts, unpositioned boom fixing locks, and abnormal tire wear.
   • Solutions: Fully tighten the chassis suspension connection points; check the boom locking device to ensure reliable locking; inspect tire wear and air pressure, and repair or replace if abnormal.
4. Abnormal Increase in Fuel Consumption
   • Causes: Rough driving habits (frequent rapid acceleration, idling), blocked air filter, and serious carbon deposits in the engine.
   • Solutions: Optimize driving operations to reduce unnecessary idling; clean/replace the air filter; perform carbon deposit cleaning and oil circuit maintenance on the engine.
