Spider Hydraulic Concrete Placing Boom The Professional Solution for Concrete Work HG21
Our Potency HG21 fully hydraulic concrete distribution rod is a smart construction machine specifically designed for efficient concrete pouring. The core design of this equipment integrates high-strength structure and advanced hydraulic control system.
The device features a three-section hydraulic folding arm structure, with a total fabric radius of 21 meters and an independent height of 4.2 meters to the arm root hinge point.
The arm can be adjusted to angles of 0 ° -90 °, 0 ° -180 °, and 0 ° -220 ° respectively, and supports 360 ° full rotation operation, meeting the flexible requirements of complex construction scenes.
The hydraulic system of this equipment is designed with high pressure of 28 MPa and is powered by a 7.5 kW motor. It utilizes HM46 anti-wear hydraulic oil to guarantee system stability. The operation mode supports both wired and wireless remote control, providing convenient remote control capabilities. Moreover, it features wind speed monitoring function to ensure safe operation, with specific wind speed parameters for fabric placement and installation.
The equipment is equipped with a combination of Φ 133 × 4.5 mm conveying pipe and 5" × 3000 mm flexible hose to meet the demands of conveying high-strength concrete. Its working temperature range is between -20 ℃ to 48 ℃, allowing for versatile operations in various conditions.

In terms of structural design, the boom is developed based on a mature platform for pump trucks. Through finite element analysis, modal testing, and fatigue testing optimization, high-strength steel plates are welded to the same level as the pump truck to ensure long-term reliability.
The mobile version can be quickly transferred through lifting equipment without the need for fixed foundations, significantly improving construction efficiency.
This series of products is widely used in scenarios such as building floors, ship borne projects, and bridge foundations, with both fixed stability and mobile flexibility.
