over a wide range of temperatures. The undercoat will resist cracking and chipping when exposed to
road vibrations, rocks, and gravel.
PREMIUM ANTI-CORROSION PROTECTION
Anti-corrosion materials will be used for highly corrosive climates. All-steel frame members will be
coated for corrosion protection and a long life. This will also include perimeter stage rail, galvanized
deck hinges, stainless steel screws, and pump compartment and control panel hinges.
PINTLE RING COUPLER
The coupler capacity will be between 9,400 and 60,000 lbs. Capacity of the pintle ring coupler will be

Plywood (FRP), for vandal resistance, weather ability, and superior acoustical properties. Interior rear
wall and end wall panels will be seamless, purlin free one-piece construction. To help reduce damage
from body flexing, these FRP panels must reinforce the structural strength of the unit.
.
City of Rosemead – Mobile Concert Stage Request for Proposal No. 2021-10

EXTERIOR BODY
Sound Shell body panels will be covered with a smooth high gloss coating that will offer a durable
vandal resistant surface and to make maintenance of the Mobile Stage body simple. Color will be
molded into the resin surface of the FRP to prevent scratching and fading of the color. Exterior will be
white, and the interior will be a medium neutral gray to help highlight the flesh tones of the performers
and to remain cool in direct sunlight. The coating will provide weather resistance to alkali, acid, and
UV degradation.
Panels will be bolted to the Sound Shell frame with self-locking and self-sealing. Bolts will be spaced
at a length that will best contribute to maximum structural rigidity. FRP panels will be easily repairable
if damaged in the field.
A heavy aluminum rub rail will extend around the bottom perimeter of the body. The aluminum rub
rail will protect the FRP and the Mobile Sound Shell frame. The rub rail will require no maintenance
or painting when scratched. The aluminum rub rail will be easily repairable in the field.
STAGE DECK
Made from plywood on aluminum or a higher-grade material, a seamless three-part composite, for its
ease of maintenance, weatherproof durability, and superior acoustics. The plywood will be coated
with a rugged weatherproof material to help eliminate the need for periodic refinishing. The top
surface will be textured for added slip resistance.
Deck surface will be free of bolts, rivets, large gaps, and exposed piano hinges at the folding deck as a
trip safety concern. Deck perimeter will have an aluminum channel with provision for stairs, skirting,
or additional deck attachments.
The deck will be medium neutral gray in color to match the interior wall, roof, and end panels. The
deck must remain cool to the touch when in direct sunlight.
NOTE: Dark colored stage decks are not acceptable due to safety concerns.
NOTE: Stage designs that require the set-up of hinged fold-in deck sections to square off the stage
deck to achieve the full rated stage length will not be accept due to time constraints.
HYDRAULIC STAGE DECK
Electrically powered hydraulic cylinders to allow for easy raising and lowering of the folding stage deck
by a person. Welded steel folding deck frame will have adjustable support legs that automatically
deploy out when the platform deck is lowered. Support legs will have both coarse and fine
adjustments for precise leveling of the platform deck.
NOTE: Independent legs, aluminum tubing, and scaffolding jacks are not acceptable since they add
additional time when setting up and retrieving loose parts.
STAGE DECK SUPPORT TRUSS
Full length truss understructure supports fold downstage deck. Hinged truss with links to mainframe
will automatically deploy as the deck is lowered to ensure a level straight deck.
City of Rosemead – Mobile Concert Stage Request for Proposal No. 2021-10

ROOF AND CANOPY
When open, the canopy eve will completely cover and extend 1’-6” past stage deck. Canopies must
be capable of extending at least 1’-6” past the stage deck to provide complete coverage. Anything
below 1’-6” will not be accepted.
HYDRAULIC CANOPY
Precision variable position hydraulic cylinders will have a pilot operated safety check valves to allow
the hydraulically locking canopy to position itself into different positions to enhance the stage
performance visually and acoustically.
Canopy hydraulic lines will be enclosed in steel end columns, at both sides of the stage, to prevent
tampering and potential damage.
Sound shell canopy will have built-in secondary automatic mechanical safety locks as a back-up to the
hydraulic safety check valves to prevent the canopy collapse in the event of a hydraulic cylinder and
line failure.
NOTE: Canopy system must have similar safety features to help prevent the collapse of the canopy
onto the crowd below. If the safety features are considered an equal, provide information on how your
safety features will avoid a canopy failure. Failure to provide this information may cause your bid to
be considered non-responsive.
CANOPY TRUSS STRUCTURE
The steel truss structure will be fully design engineered to handle the load of the roof, lighting & stage
equipment, other equipment, and natural events.
For example, the light & sound equipment will be installed from the ground level and safely lifted
overhead, require a minimum equipment load capacity of 1,200 lb. at the canopy leading edge for
safety. Will not accept the installation of any vertical upright corner post that are used as secondary
supports.
HYDRAULIC SYSTEM
The operation of the Mobile Stage roof, canopy and deck will be a self-contained hydraulic system
which will be operated by a remote-control pendant. The unit will have a locking control panel and a
security latch for the hydraulics and control system. All hydraulic lines will be flexible enough to allow
for stage movement during tow and set-up.
The Mobile Stage Sound Shell mechanical components will include a battery, battery charger, hydraulic
pump, and fluid reservoir which will be located in a locking, weather-tight aluminum compartment.
All mechanical components will be conveniently located for ease of service and protected from
weather conditions.

12VDC ELECTRICAL
The stage will be equipped with all ICC road lights and license plate bracket with light. Marker lights
and stage 12VDC marker lights will have a rugged die-cast aluminum housing for protection. The stage
will have a connector cable, connector, and towing vehicle receptacle. All 12VDC wiring will be run
through a protective loom. All DOT required lights will be LED.
Hydraulic system will be powered by one (1) 12V deep-cycle marine batteries (12VDC) equipped with
a battery charger. The deep-cycle batteries and charger will be in a mechanical locking compartment
at the rear of the stage. The deep-cycle batteries will provide power to the electric hydraulic pump
that operates the hydraulic cylinders and the handicapped lift. Fully charge batteries will open and
close the mobile stage and the handicapped access lift at least a minimum of ten (10) times.
When the power cable is hooked up to the AC electric power, the 12VDC/5 Amp. charger can be
plugged into an outlet in the locking compartment to charge the batteries. After approximately eight
(8) hours of charging, the batteries will be fully charged. The handicapped access lift is 12VDC powered
and will run while the charger is charging.
Neither the deep-cycle batteries nor the charger will require removal from the stage during the
charging process. An extension cord to the charger will provide a maintenance charge without hooking
up the mobile stage main power cable.
110V/60HZ ELECTRICAL SYSTEM
Sound Shell will be equipped with a 125 Amp./220/110V load center with three (3) 20 Amp. breakers
and 50' 6/4 W cable with 15 Amp. Receptacles will be located at each inside end of the start and in the
mechanical compartment. U-ground plug connector.
