Product Features

Core System Components

The system employs an integrated “pump-material-control” architecture, consisting of a concrete pump, an automatic metering cart, a variable-frequency drive system, load cells, and a PLC controller. Concrete is delivered directly into the reinforced steel cage through sealed pump lines, avoiding contact with the ground and preventing splashing, thereby reducing waste and pollution.

Automatic Metering and High-Precision Weighing

Integrated load cells monitor the concrete weight inside the mold in real time, automatically stopping pumping when the preset value is reached. This eliminates the inaccuracies of manual estimation, ensuring precise material usage and uniform wall thickness for every pipe pile or utility pole.

High-Precision Variable Frequency Drive and PLC Integrated Control

Utilizing variable frequency speed control combined with PLC control, the system achieves precise coordination between the flatbed truck’s speed, pumping rhythm, and mold position. Parameters are entered via a touchscreen for one-touch automatic operation, with support for switching between manual and automatic modes.

Concrete Pumping Equipment Configuration

Standard configuration includes the HBT60/1613S concrete pump with an S-valve structure, which minimizes directional change impact and reduces the risk of pipe blockages. It supports flow rates of 20–100 m³/h, outlet pressures of 4–16 MPa, and horizontal delivery distances of 1,000–1,200 m.

Encoder and Position Detection

An encoder is mounted on the main shaft of the transfer car, providing real-time position feedback to the PLC. The control screen displays the transfer car’s position, travel distance, and pouring points, enabling precise multi-section placement for long forms.

Robust Structure and Weather-Resistant Design

Designed for high-dust, humid, and vibrating environments, key components include cast steel bases, double-row sprockets, and wear-resistant parts. Piping systems feature reliable sealing and low failure rates, making them suitable for long-term continuous production.

Product Applications

Automated Concrete Placement for Pile Production

Used for closed-loop pumping and placement of PHC piles and prestressed piles. Concrete is injected directly through pipes into the closed mold; the system automatically stops when the target weight is reached. This ensures no leakage at the joints, no indentation of the skirt plate, and uniform wall thickness in the finished product.

Closed-Loop Pumping for Prefabricated Utility Poles

Suitable for tapered utility poles, uniform-diameter utility poles, and utility poles with flanges. Pumping occurs after the mold is closed, eliminating the slurry leakage and wall thickness deviations associated with traditional open-loop placement. It also supports flexible sequencing with pre-tensioning before pumping.

Precast Component Production Line Integration

Serves as the core placement module for automated precast component production lines, integrating with curing kilns, feeders, vibrating tables, and other equipment. Supports PLC integration with MES systems to enable production volume tracking and quality traceability, requiring only a small number of operators per shift.
