JLG REACHES FOR
Newest boom lift hits more than 185 ft.
JLG, the McConnellsburg, Pa.- based manufacturer of aerial work platforms, has launched
what it calls the world’s largest self-propelled boom lift — the 1850SJ Ultra.
With a maximum reach of 185 ft. 7
in., the 1850SJ delivers more than 2. 9
million cu.ft. of work area and offers
more than 35 ft. more reach than the
company’s next biggest model, the
1500SJ, which was introduced in 2011.
With 19 stories of working height,
the new boom lift moves into applications previously reserved for truck-
With a maximum reach of 185 ft. 7 in., the new 1850SJ Ultra is the largest self-propelled
boom lift manufactured by JLG. The boom is powered by a Deutz TD 3. 6 L diesel engine
rated 99.8 hp.
mounted booms, the company said.
The 1850SJ, which went into production last year, is aimed at specialized
applications, including wind farms and
other energy markets as well as stadium construction and maintenance,
and entertainment and studio-related
work, the company said.
The 1850SJ offers a maximum
capacity of 1000 lb., which should
enable operators to move more tools
and materials to the elevated work-
site, the company said. The five-
section boom is designed to extend
from ground to full height in less than
five minutes. Moreover, the 1850SJ
includes a jib that extends and retracts
from 13 to 20 ft. to provide additional
reach, up-and-over capability and the
ability to telescope into and around
structures, the company said. The jib
also has a 120° articulation range,
and the operator can move just the jib
rather than the whole boom for great-
er maneuverability and more precise
positioning, the company said.
The boom is powered by a Deutz
TD 3. 6 L diesel engine rated 99.8
hp. The four-cylinder engine has a
bore and stroke of 98 x 120 mm. The
boom’s drive and function pumps are
supplied by Danfoss, and Reggiana
Riduttori supplied the drive hubs.
The 59,930 lb. 1850SJ has a horizontal reach of 80 ft. and a maximum
ground bearing pressure of 119.6 psi.
The machine can travel on as much as
a 40% grade and has a top speed of 2. 8
mph, the company said. The axles take
approximately one minute to extend
or retract, and they are able to pivot in
and out — they do not telescope like
extendable axles on other Ultra series
boom lifts, the company said.
JLG said that the new boom lift
does not require an oversized-load
permit, which is a benefit to operators
because oversized permits can be
expensive and take several days to
obtain. Oversized loads also usually
require an escort vehicle. A 53 gal. fuel
tank is designed to enable 24 hours of
continuous operation before refueling,
the company said.
In addition, the 1850SJ incorporates an updated platform LCD display designed to provide more information to the operator. A graphic
display of the operator’s position in
the work envelope is designed to aid
in positioning. The communication
of service codes, engine status, fuel
levels and other messages assists
the operator and service provider
with operation, diagnosis and troubleshooting, the company said. dp
