Aluminum cantilever slide gates shall conform
to ASTM Specification F-1184 "Specification
for Industrial and Commercial Horizontal Slide Gates"
and to the following specifications:
ENCLOSED TOP TRACK shall be a single
track and rail aluminum extension weighing 5.25
pounds per foot and shall have a minimum 1-1/4"
wall thickness at any dimension. The track shall
be designed to reduce lateral movement. The top
track shall conceal the truck assembly and protect
it from the elements. Top track shall be formed
to accept the 2" x 2" square vertical
and 1-1/4" x 1-1/4" square diagonal members
of the gate.
BOTTOM TRACK shall be a single
aluminum extrusion formed to accept the 2"
vertical and 1-1/4" diagonal members of the
gate. Wall thickness of bottom track shall be minimum
3/16" in cross section. The bottom frame shall
also be designed to reduce lateral movement.
SAFETY SEAL: Both top and bottom
tracks shall be extended to include a keyway into
which the ends of the filler material (such as chain
link fabric) shall fit and protect both bystanders
and the gate.
GATE FRAMES: Vertical members shall
be made of 2" square aluminum tubing, with
a 1/8" wall thickness, alloy 6063-T6, weighing
1.09 pounds per lineal foot. Verticals shall be
welded top and bottom to form a rigid unit. Diagonal
members shall be made of 1-1/4" square aluminum
tubing, with 1/8" wall thickness, alloy 6063-T6,
weighing .655 pounds per lineal foot. Diagonal bracing
shall be solidly welded in each section (or bay)
to prevent sagging.
TRUCK ASSEMBLIES shall consist
of two (2) heavy duty swivel type trucks having
four horizontal wheels with factory sealed and lubricated
roller bearings. There shall be two (2) high impact
lateral wheels to insure alignment of the truck
in the top track.
HARDWARE: All gate hangers, latches,
brackets, and associated hardware shall be galvanized
after fabrication. Hardware shall meet or exceed
ASTM specifications F 626 & A 153.
GATE POSTS: Gates shall be installed
on 4" OD Schedule 40 galvanized posts weighing
