    Parameters
    Truss Parameters
    Diameter of top chord steel bar φ6~φ14mm
    Bottom chord steel bar diameter φ5~φ14mm
    Diameter of web bar φ4~φ8mm
    Total height of straight truss (F+H)=70~350mm;
    Height from bottom chord to bottom Curved truss C=15~30mm;
    Straight truss F=0~30mm (F value should satisfy 70≤(F+H)≤350mm)
    Plane truss H=70~350 mm
    Bottom width of triangular truss Curved truss A=135~140mm; straight truss b=60, 80mm
    Feet folding length of triangular truss B=30mm

    Raw material requirements
    The upper and lower chords are made of spiral ribbed deformed reinforcing steel bars, which meet the standard requirements of GB14981-2004 "Dimensions, shape, mass and tolerances for hot-rolled wire rods".
    The web bar is made of plain round bars, which meets the standard requirements of GBT 14981-2004 "Dimensions, shape, mass and tolerances for hot-rolled wire rods".
    The maximum speed of the production line (test sample TD3-100): 15-20 m/min for conventional bent truss
    Total equipment power:
    Welding power source: using the latest AC frequency conversion technology, the installed capacity of the transformer is 200kW x 4 units
    Power consumption of welding system: 250 kVA (variable frequency power supply)
    Installed power of motor: 80 kW
    Mode 3000 chiller: ≈ 13 kW (Outsourced equipment, subject to the delivery)
    Actual power consumption of the production line under normal production: about 60kW (motor)
    Power supply: 380V/50 Hz three-phase AC
    Ambient temperature: -5~45 ℃
    Truss length: 2-12 m (optional in 2-6 m)
    Water-gas-liquid parameters:
    Cooling water flow: ≥100 L/min (On the premise that the cooling effect of the equipment can ensure the normal circulation of the cooling water, the cooling water must be pure water, and antifreeze must be added when the temperature is below zero.)
    Compressed air pressure: ≥0.6 MPa
    Compressed air flow: ≥1 m3/min
    Hydraulic pressure: 16 MPa
    Dimensions of production line: ≈45000×5000×4500 mm (L×W×H)
