In concrete pouring construction, the fabric radius and number of boom sections of the fabric machine directly determine the pouring coverage, construction efficiency, and on-site adaptability. Many procurement projects often struggle with: what is the required fabric radius for the project? Choose two arms or three arms? What scenarios require an extended arm? Choosing the right boom can reduce the number of equipment shifts, lower labor costs, and avoid blind spots during pouring; Improper selection can result in limited construction and repeated machine movements that delay the project schedule, or in severe cases, insufficient floor space that prevents the deployment of the boom, leading to idle and wasteful equipment.

The selection of fabric radius should first refer to the size of the pouring working face. When selecting, you cannot only choose based on the net size of the floor, you need to reserve a safety margin. It is recommended to reserve an additional 1.5-2 meters of space on the actual coverage area to avoid obstacles such as beams, scaffolding, formwork, and steel bars on site. For example, for the pouring of ordinary high-rise residential floors, most models with fabric radii of 15 meters, 17 meters, and 21 meters are used; Large garage, beam making yard, and large foundation slab can be equipped with 24 meter and 28 meter long arm fabric machines. For construction sites with narrow floors, indoor construction, and limited space, it is not advisable to blindly choose large radius models. Insufficient space for arm deployment may hinder normal operations.

Two section arm and three section arm are the two most common arm forms of hydraulic fabric machines, with significant differences in applicable working conditions. The two arm structure is simple, the boom deployment logic is simple, the failure rate is lower, the maintenance is convenient, the self weight is relatively lighter, and the floor load pressure is smaller. Suitable for open and unobstructed working surfaces, bottom plate pouring, prefabricated component yards, with simple working conditions and few obstacles, pursuing stable, reliable, and low-cost operation and maintenance projects.

The three section R-shaped folding arm is the preferred choice for complex working conditions. Having an additional folding joint makes the arm frame more compact and takes up less space after retracting the arm; Multiple pitch adjustments during unfolding can flexibly bypass obstacles such as beams, columns, walls, and steel structures, eliminate blind spots in pouring, and achieve three-dimensional fabric distribution. For high-rise building floors, basements with a large number of columns, and construction sites with narrow spaces, priority should be given to using a three arm fabric machine. Although the structure is more complex, wireless remote control operation allows for flexible pitch and rotation, and in the construction of complex building structures, the overall construction efficiency far exceeds that of two arm models.

Not all projects require an extended arm fabric machine. The extended arm is generally used for large-area base plates, large factories, bridges, offshore platforms, and large-span infrastructure projects, which require covering a large pouring area at once to reduce the number of times the fabric machine is moved and disassembled. The extended arm has higher standards for the overall structural strength, floor load-bearing capacity, and wind resistance of the machine. It is necessary to calculate the site load and spatial conditions in advance, and cannot be blindly selected.

As a professional manufacturer of concrete material distribution machines, Zhongfan Heavy Industry has a complete product matrix of arm frames, with fabric radii covering 12 to 32 meters. Two section arms, three section R-shaped arms, and non-standard extension arms can be customized according to needs. The arm frame is made of high-strength steel plate welded as a whole, and has undergone stress relief treatment. It is anti fatigue, not easy to deform, and has a six level wind resistance design. It is suitable for various complex working conditions such as high-rise buildings, tunnels, muddy construction sites, and ships.

All arm frames undergo load testing before leaving the factory to ensure the safety and stability of long-term high-frequency pouring operations. The manufacturer‘s technical team can assist in calculating the fabric radius one-on-one based on construction drawings, site conditions, and floor loads, recommend the most suitable number of boom sections, and avoid selecting pitfalls. We provide one-stop concrete pouring solutions from equipment production, on-site installation guidance, operator training, to later accessory supply and after-sales maintenance.

In engineering construction, selecting a material feeder is not only based on the size of the parameters, but also on matching the working conditions of the boom, in order to maximize pouring efficiency and save construction costs. Zhongfan Heavy Industry focuses on the research and production of various concrete fabric equipment, providing reliable fabric equipment for domestic and foreign housing construction, infrastructure, and overseas export projects.
