GLOBETRAY Splice Plates are heavy-gauge metal to provide a
connection between tray sections with a resistance of not more than 0.00033 ohms (see NEMA
Standard VE-1). NOTE: All splice plates are supplied in pairs with all necessary hardware.
GLOBETRAY splice connectors are complete with 3/8"
dia. truss-head ribbed shank bolts and serrated flanged nuts. Locking shanks of bolts
prevent rotation while being tightened. Nut and bolts are steel with an electro-galvanized
finish. Bolts should be torqued to 33 ft.-lbs.
ADJUSTABLE SPLICE PLATES
Horizontal vertical adjustable splice plates are provided
to make random-angle connections between sections of tray. A grounding strap is
recommended for electrical continuity. Horizontal adjustable splice plates can be used
with trays of all depths.
SPHA:
SPHA is used on inside angles. Use a fitting divider strip to form an outside rail.
Cadmium plated.
LOAD-REDUCTION FACTORS FOR SPLICE CONNECTIONS
NOTE (1): Since spliced joints normally have a lesser load
capacity than tray sections, splice locations confined to points of minimal stress take
fullest advantage of cable tray strength. Optimum splice locations are at approximate
quarter points (one-fourth the clear span distance from the support), or next best,
between quarter-points and nearest tray support. For these locations allowable loads found
in previous pages of this catalog may be used without reduction.
NOTE (2): IF spliced joints occur at or near midspan, tray
section allowable loads must be reduced, amount depending upon span condition and model of
tray and splice plate. The reduced allowable load can be found by multiplying the normal
allowable tray load from previous pages, by the corresponding "load-reduction
factor" from the chart below
Because cable tray fittings require additional support, the
load-reduction factors below are based on the assumption that spans comprise straight
sections only.
NOTE (3): Splices must be avoided in: (1) single spans, (2)
end spans of multiple spans.
