1 Two
Spanning Angles or Spanning Channels required per Suspension
Clamp System, purchase though your local vendor.
2 Angles and Channels are back-to-back, but spaced apart by Suspension Clamps.
3 Allowable net load, per pair, may be located anywhere along the span. Weight
of angles or channels has been accounted for.
4 Angle dimensions are listed "Vertical Leg" x "Horizontal Leg" x "Thickness".
5 No values below 500 lbs. are listed. Allowable loads have been limited to 2,000
lbs. maximum. |
|
6
Allowable loads are based on 36 ksi minimum yield steel and the
AISC specifications.
7 A single load equal to the tabulated capacity or multiple loads with a sum
equal to the tabulated capacity is allowable.
8 Live Load Capacities based on Safety Factor of 2.0.
9 Loads in bold (528) are governed by deflection limit of Span/ 240; (e.g., 0.500''
for 10' span).
10 Tabulated values are based upon the additional bracing provided by Suspension
Clamp System.
11 Tabulated loads based on vertical loading only. |
