Installation Typicals - Fastening on Steel Threaded Studs

USAGE / STRUCTURAL DESIGN EXAMPLE
LOADS* — CABLE TRAY AND PIPE
*Loads are typically stated in technical
documents as “Force [kN]”, however it
is more comprehensible to state the loads
as “Weight [kg]” conversion as follows:
1 kg = 9.81 N / (weight to force):
100 kg = 0.98 kN;
1000 kg = 9.8 kN / (force to weight):
1 kN = 102 kg;
10 kN = 1019 kg
Cable tray Width [mm] Load [kg/m] Load [lb/ft]
50 W x 50 H 50 7.7 5.2
100 W x 50 H 100 14.5 9.7
150 W x 50 H 150 21.2 14.2
200 W x 50 H 200 27.9 18.7
300 W x 50 H 300 41.4 27.8
450 W x 50 H 450 61.6 41.4
600 W x 50 H 600 81.9 55.0
900 W x 50 H 900 122.3 82.2
• Load [kg/m] includes the cable tray and cable carried by the cable tray
(by simplified calculation)
• Cable tray weight (steel, t = 1.25 mm) is in the range of 1.5 – 9.8 kg/m
(for width of 50 – 900 mm)
• Cable weight is calculated based on an average filling density of 0.25 kg/m/cm

cable tray cross-section typical cable range from 0.15 – 0.35 kg/m/cm

Pipe Diameter [mm] Load [kg/m] Load [lb/ft]
25 DN x 33.4 OD 25 3.6 2.4
40 DN x 48.3 OD 40 6.1 4.1
50 DN x 60.3 OD 50 9.8 6.6
80 DN x 88.9 OD 80 15.8 10.6
100 DN x 114.3 OD 100 31.0 20.8
125 DN x 141.3 OD 125 45.9 30.8
150 DN x 168.3 OD 150 63.6 42.7
200 DN x 219.1 OD 200 96.9 65.1
• Load [kg/m] includes the pipe and media (by simplified calculation)
• Pipe weight is in the range of 3.0 – 57 kg/m (for diameter of 25 – 200 mm;
with 1 mm pipe insulation)
• Media weight is calculated based on density of water 1.0 kg/l
(per pipe cross-section) density dependent on media (e.g. oil 0.6 – 0.9 kg/l)
Example loads* can be calculated
based on a standard cable tray
with 50 mm height or pipe
(see example tables to the right)
