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.
