we build each tank
contour a semi-rectangle and continue this unique shape the full length
of each tank, through the canbox. This method provides a trim low profile
and low center of gravity to minimize load shifting in transit.
Featured with our nude, canopied meter box and other
tank styles. Side delivery offers protection from oncoming vehicles, while
the covered working area protects the driver during inclement weather.
Combined with a full rear head on side-access tanks
to keep interior equipment clean and dry. The open, quick entry, canbox
area makes it easy to reach the hose, meter, and pumping components.
to absorb chassis twisting and the movement of a live payload. This is
accomplished by making extra thick tank bottoms and positioning heavy
duty supports along each tank bottom to reinforce the mounting rails at
all stress points.
That's our term for our extended deep scoop on all
baffles and heads. They are flanged around the entire perimeter for additional
strength and welding reinforcement. This technique gives you a stronger
tank and increases load stability. All heads are die pressed at our own
plant using proprietary Boston tooling and machinery.
materials, and extra welding and finishing work at all payload stress
angles and corners. High performance steel resists impact damage and corrosion,
and our aluminum tanks make equal claims to workmanship and durability.
Both our aluminum and steel tanks are finished smooth for a lasting paint
or decal bond.
For all designs, we provide easy access to the tank
and working delivery equipment. Auxiliary components, such as fenders
and bumper guards, are easily removed should repair be needed.
Meets or exceeds all Federal/State standards and regulations.
The design and fabrication of the tank flashing provides vent protection
in case of turnover. All Boston tanks are warranteed for five years from
defects under customary delivery usage.
key to correct tank construction lies in bottom materials, head/baffle
materials, and design. BOSTON's engineering provides strength at the area
over the truck frame where stresses are most prevalent and carries it
up through the tank via the heads.
ALUMINUM AND STEEL TANKS MEET OR EXCEED DOT 406 CONSTRUCTION REQUIREMENTS:
AXLE ALUMINUM TANK:
.313" extruded mounting subframe
.216" heads & baffles
.173" side shells & top
.313" extruded mounting subframe
.216" heads & baffles
.173" side shells top
supports (inriggers) at every head and baffle, plus cradles up to side
shells (outriggers) on tandem chassis or on tanks destined for rough service
usage. This combination of thicker tank material plus design additions
that provide better and longer lasting service (inriggers, outriggers,
cadmium plated tie down bolts) have been the key to Boston's growth, longevity,
and lack of warranty problems.
Boston tanks feature deep dished, semi- rectangular heads and
baffles for strength and a low profile center of gravity. Baffle openings
are reinforced and offset to prevent product surge. A wide range of
head sizes allows custom fabrication to various chassis wheelbases.
Radius sides provide tank strength and large smooth panels for customer
Thick bottom section has 96" rolled radius for strength.
Wide longitudinal box type sub-frame mountings continuously welded
to the tank bottom. End caps add extra support. Aluminum mounting
extrusions feature support feet to cradle the bottom and wood sill
retainer flanges. Steel mountings have internal vertical gussets for
strength. Mountings also serve as hose carriers for 3" drop hoses.
Brackets are attached to both steel and aluminum mountings at each
end to retain the hard wood sills.
Overturn rails are designed and constructed in accordance with DOT
406 specifications and provide protection for manholes and vents.
Overturn rails are full length, continuously welded and can be used
for vapor recovery. Expanded metal completely covers the inside walk
area. The tank top has four (4) 1 1/2" flashing drains to drain
rainwater no matter how the tank is pitched.
The tank has Betts Industries DOT manholes with two (2) vents
in each cover for increased venting. Each compartment includes an
aluminum seal/calibration rod.
Fenders are short leg "Jeep" style bolted to heavy duty
mounting brackets which provide protection from road salt and spray.
All lights, wiring, and switches are vapor proof. The lighting system
is Betts Industries "Sealed Lighting System" with non-corrosive
light housings with lexan lenses. Chassis wiring is connected inside
a non-corrosive junction box. Hose reel wiring is vapor proof with
solenoids and circuit breakers enclosed within junction boxes.
Stainless steel continuous hinges and high quality hardware is used
on accessory equipment.
A wide front ladder with large top step landing and grab rail is standard
on all tanks. A rear ladder with grab rails is available at no extra
||EXTERNAL TANK SUPPORT
Formed cradles or inriggers support the tank bottom and mounting sub-frame
under every head and baffle. External bolsters or outriggers with
pads are an additional standard feature for tanks mounted on tandem
chassis or tanks destined for demanding service.
The rear DOT 406 bumper consists of 1/4" steel rectangular tubing
built into the truck frame with 1/4" 406 frame pan and 1/4"
406 vertical panels. The size of the tubing depends on the capacity
of the tank. An auxiliary bumper of 1/4" steel double formed
channel is bolted to the 406 assembly for added rear end protection.
Standard width is 78" with 96" full width bumper available.
An aluminum auxiliary bumper is optional.
Made of 3/4" cadmium plated steel with double spacer bars for
added holding power. DOT 406 steel box channel tie down restraints,
engineered for each size tank and bolted to truck frame, compliment
the tie down arrangement. These specially designed tie downs enable
each tank to resist movement in any direction. BOSTON employed the
services of an MIT engineering consultant to design this tie down
system. Spring mount front tie downs are standard on tandem vehicles.
Hard wood sills with front taper relief are custom cut in order to
cushion each tank we make.
