28Mpa Hydraulic System Concrete Placing Boom with 360° Slewing Angle and 4.2m Stationary Height Spider HG21
28Mpa Hydraulic System Concrete Placing Boom with 360° Slewing Angle and 4.2m Stationary Height Spider HG21
Product Description:
Our Potency HG21 fully hydraulic concrete distribution rod is an intelligent construction machinery designed specifically for efficient concrete pouring. Its core design integrates high-strength structure and advanced hydraulic control system.
The equipment adopts 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, adapting to the flexible requirements of complex construction scenes.
Features:
The hydraulic system is designed with a high pressure of 28 MPa and is powered by a 7.5 kW motor drive. It uses HM46 anti-wear hydraulic oil to maintain system stability.
The operation of the system supports both wired and wireless dual-mode remote control, providing convenient remote control capabilities. Additionally, it features wind speed monitoring functionality to ensure safe operation. Wind speeds should be below 13.8 m/s during fabric placement and 7.9 m/s during installation.
The equipment is configured with a combination of Φ 133 × 4.5 mm conveying pipe and 5" × 3000 mm flexible hose to meet the demands of high-strength concrete conveying. The working temperature range of the equipment spans from -20 ℃ to 48 ℃.

Applications:
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.
