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. |

a) Allowable concentrated load at middle of span. Allowable
loads are net (weight of tube has been accounted for).
b) Multiple loads, that are symmetrically placed and whose
total equals the tabulated value, may be used.
c) The reaction to each clamp bracket must be limited to a net
value of the clamp's charted capacity.
d) Allowable loads have been limited to 2,000 lbs maximum. |
|
e) Allowable loads are based on 46 ksi minimum yield steel
(A500, Gr. B), the AISC specification and a safety factor of 2.0.
f) Loads in bold (1,067) are governed by applied-load deflection
limit of Span / 240; (e.g., 0.50" for 10' span).
g) Tube's 4" dimension is vertical. Span is horizontal.
h) Tube weights: 4.75 lbs/ft for 1/8" wall, and 6.87 lbs/ft for 3/16"
wall. Weights and thicknesses are nominal. |

a)
Short dimension of tube cross-section is vertical, parallel
to load (minor axis bending).
b) Allowable, net concentrated load, per tube, may be located
anywhere in the span. Weight of tube has been accounted for.
c) Allowable uniform load is the net loading on the tube.
Weight of tube has been accounted for.
d) allowable loads are based on 46 ksi minimum yield steel
(ASTM A 500, Gr. B) and the AISC specification.
e) All net (applied) loads are governed by deflection limit
of Span / 240; (e.g., 0.250" for 5' span)
f) Tube-wall thicknesses are nominal. Minimum is 0.93 times
nominal, per 2005 AISC specification.
g) Allowable loads ("max" loads) arebased on a safety
factor of 2.0. |
