CAPACITY
All units must be designed to carry a uniform live load of at least 200
lbs. per square foot. Written laboratory test data must be submitted on
request.
PORTABILITY
The stage system shall be capable of being completely set-up and
dismantled quickly, without special tools, by two persons of average
physical strength.
CONSTRUCTION
DECKING
A solid, plywood core shall be surfaced with one of the following:
OPTION 1: 1/8" thick tempered hardboard - OPTION 2: polypropylene sheet
- OPTION 3: carpet. The decking shall measure at least " in thickness.
The perimeter of the decking shall be routed to allow the frame to fit
flush with the top surface and cover the edges of carpeting.
FRAME
A 16 gauge, formed steel channel, 1-13/16" high shall be reinforced with
a 16 gauge steel angle welded to the inside of the channel. The angle
shall provide a continuous support to which the decking is secured with
screws placed a maximum of 9" apart. The frames shall completely enclose
the top, bottom and edges of the decking perimeter preventing the
decking and any specified covering from becoming loose or damaged. All
areas where frame members are joined together shall be reinforced with
steel plates attached with rivets.
LEG STRUCTURE
(Fixed Height)
Each leg assembly shall be constructed of 1.05" diameter, 14 gauge steel
tubing capped at the point of floor contact with high impact plastic
glides. The vertical load bearing members shall be joined at the top by
a full width, steel tube to provide maximum support to the stage deck.
The top of each leg assembly shall fold open and closed, rotating within
16 gauge steel saddle clips that are secured with at least four screws.
Leg assemblies shall be braced by friction type braces, equipped with a
spring locking device to secure the legs in the open and closed
position. Braces shall be secured to the leg assembly with rivets and to
the decking using a minimum of six screws and two bolts installed
through the decking. It shall require only three leg assemblies to fold
when opening or closing each riser unit. Legs shall open and close using
only one hand. Gravity ring type brace locks are not acceptable.
LEG STRUCTURE
(Dual Height)
Dual height leg assemblies are to be constructed, attached and shall
fold in similar fashion to fixed height leg assemblies, but shall be
constructed of 1.05" and 1.25" diameter, 14 gauge steel tubing. The leg
assembly shall be constructed to allow the stage height to be positioned
at two different heights having an eight inch differential. Braces shall
open and close with one hand. Gravity ring type brace locks are not
acceptable. Height adjustment shall be made by rotating the leg 180
degrees and engaging it into a locking stud. Stage units shall require
only three leg assemblies to be adjusted to accomplish a change in
height.
COUPLING
Stage units shall be equipped with drop-in type couplings that allow
stage units of the same or different heights to be joined together. All
couplings shall be permanently secured to each unit. Coupling devices
not permanently attached are not acceptable.
METAL FINISH
All metal parts shall be thoroughly cleaned and phosphatized to enhance
paint adhesion. Metal parts are to be finished with a thermofused epoxy
powdercoating. All painted metal components shall be furnished in black
or brown color.
ACCESSORIES
GUARD RAILS
Guard rails shall be furnished to protect the back and sides of the
stage as well as both sides of any stairs to be furnished. Guard rails
shall be constructed of 1" diameter, 14 gauge, powdercoated, steel
tubing. Guard rails shall quickly attach to stages by clamping on to the
frame and bolting through the decking. Bolts and threaded inserts shall
be provided by the manufacturer.
STEPS
Steps shall be surfaced with slip resistant, gray polypropylene. Step
units shall clamp securely to any area of the stage perimeter. Units
shall have ______ levels. Each step shall be 36" wide x 12" deep and
shall have a rise of 8". {OPTIONAL: Hand rails shall be provided for
both sides of the step units.}
CADDIES
Caddies shall be provided to store and transport all stage units to the
event location and safely hold each unit until legs are folded open and
the unit is rotated to the floor. Each caddy shall be capable of holding
6 units.
WARRANTY
All stage components shall be free of defects in materials and
workmanship for a period of ten years. Any defects discovered and
reported in writing within the warranty period shall be corrected by the
manufacturer at no cost to the owner. |
