Cable Tray Bend Fundamentals
Bend Geometry
Cable tray bend calculations consider:
- Arc length based on radius and angle
- Material development length
- Structural integrity requirements
Installation Factors
- Minimum bend radius requirements
- Support spacing considerations
Key Formulas:
Arc Length = (π × R × θ) / 180
Total Bend Length = Arc Length + Straight Sections
Material to Bend = Total Bend Length / 1000
Cutting Angle = Bend Angle / 2
Calculation Formulas
Arc Length:
L = (π × R × θ) / 180
Total Bend Length:
D = Arc Length + Tangent Lengths
Material to Bend:
A = Total Bend Length / 1000
Cutting Angle:
C = Bend Angle / 2
Example Calculation
Ladder Tray 90° Bend:
Width: 300mm
Height: 100mm
Bend Angle: 90°
Bend Radius: 600mm
Arc Length = (π × 600 × 90) / 180 = 942.48mm
Total Bend Length = 942.48 + 200 = 1142.48mm
Material to Bend = 1142.48 / 1000 = 1.142m
Cutting Angle = 90 / 2 = 45°
