N
itrogen plays a key role in servicing and maintaining
aircraft. Unlike oxygen, nitrogen is an
inert gas and therefore is not flammable. Nitrogen
is used in low pressure (up to 320 psi) applications for
aircraft tire inflation and high pressure (up to 3500 psi)
applications to service struts, accumulators and other
components.
Most commonly used for inflating tires, Semmco's Nitrogen
SMART Trolley offers three demountable cylinders.
Compared to other Semmco nitrogen trolleys, such as the
Nitrogen Trolley - 2 Cylinder Demountable, the SMART trolley
is considered an entry-level option with a more compact and
efficient design.
" It's a really good, cost-effective, entry-level product for us
in quite a competitive market, " says William McOnie, sales
and business development manager - USA, Canada and
South America.
Perhaps its most unique feature is its pivoting cylinder
cradle. On some trolleys, the cylinders are positioned horizontally.
On the SMART trolley, the cylinders, standing upright,
can be rolled onto a pivoting cradle. As a result, no lifting of
the cylinders or other lifting equipment is required. Once the
cylinders are in place, the cradle then is reclined to about 135
degrees and the trolley is ready to roll. To take cylinders off
the trolley, the cradle again is pivoted to 90 degrees.
" It's a lot easier and more efficient, " McOnie says, noting
each cylinder can weigh approximately 70 pounds.
McOnie points out having the SMART trolley reduces the
need to bend and lift, and therefore reduces back pain and
workplace injuries.
" The cradle design is very clever, " he says. " When we
designed it, we were able to shave off some components,
which are a nicety in the standard trolley, which enabled us to
call back some material costs and offer a slightly more competitive
price to the customer. "

The Semmco Nitrogen SMART
Trolley is designed to carry
three nitrogen cylinders, which
are mounted on a cylinder
cradle for safe, quick and easy
loading and unloading.
The design is also smaller, lighter weight and easier to
maneuver around compared to the standard trolley, he adds.
In fact, the SMART trolley, which fits up to three cylinders
is actually lighter than the standard trolley with two cylinders,
which is made with more steel.
The use of three cylinders is not required with the SMART
trolley but gives customers more capacity than a standard
two-cylinder trolley. McOnie says Semmco customers generally
prefer having a two- or three-cylinder capacity.
Several safety features have been incorporated into the
SMART trolley. To prevent overinflation, there's automatic
shutoff. The control panel also is designed with color coding
(blue for low pressure and yellow for high pressure), as well
as different hose and fitting sizes. Only the low pressure hose
can connect to the low pressure fitting and the high pressure
hose can only connect to the high pressure fitting.
The weight of the trolley without cylinders is 195 kg (about
430 lbs.). Dimensions are about 2 m (6.75 feet) by 1.22 m
(about 4 feet) by 1.33 m (4.36 feet). The trolley is made with
