3 Sections Boom Arms and 4.2m Stationary Height Hydraulic Spider HG21 Placing Boom for Precise Concrete Placement

Product Description:

Our Potency HG21 fully hydraulic concrete distribution rod is a smart construction machine meticulously crafted for efficient concrete pouring. Its core design seamlessly incorporates a high-strength structure and an advanced hydraulic control system.

The equipment 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 offers adjustable angles of 0°-90°, 0°-180°, and 0°-220°, along with 360° full rotation capability, making it well-suited for the diverse demands of intricate construction sites.

Features:

The hydraulic system of the equipment adopts a high-pressure design of 28 MPa, powered by a 7.5 kW motor drive, and utilizes HM46 anti-wear hydraulic oil to maintain system stability.

The operation of the equipment supports both wired and wireless dual-mode remote control, allowing for convenient remote operations. Additionally, it is equipped with wind speed monitoring function to ensure safe operation, with specific wind speed requirements during fabric placement and installation.

The equipment is designed 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. It offers a wide working temperature range from -20 ℃ to 48 ℃ to handle various operating conditions.

Technical Parameters:

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.
