Cable Tais Chaw thau khoom Information

Load xeem raws li EN 61537: 2007
Q = UDL (uniformly faib load)
Safety Factor = 1.7
L = intermediate saib ntsoov txog
F = deflection = 1/100 ntawm lub intermediate ncua (max.)
S = splice qhov chaw
hais loadings thov kom me me steel khoom tsuas .
Besca lub load xeem yog nyob rau hauv raws li EN 61537: 2001. Nyob rau hauv cov tswv yim cov ntsiab lus no npog tas mus li / multi
luv sib, tusyees loaded raws qhov ntev ntawm, thiab thoob plaws rau tag nrho cov dav ntawm lub tais. Qhov kawg spans nyob rau hauv
these installations should be reduced to 0.75 of the intermediate spans.
DEFLECTION: Besca’s load and deflection figures are in accordance with EN 61537:2007, with the characteristic
deflection of Unistrut Cable Tray limited to span/100 and load figures inclusive of a safety factor of 1.7.
ACCESSORIES: To ensure adequate support, accessories should be supported locally.
COUPLERS: The loading and deflection tables for Unistrut Cable Tray assume that the couplers are located at the
most onerous position within the span (i.e. mid span). To maintain the load/deflection figures stated in the tables,
the couplers should not be located in end spans or over support locations. Straight couplers were utilized for the
testing of the medium and heavy duty cable trays. Only one pair of couplers should be used per span.
