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°
