Moving up
Due to the environments that
rough terrains are working in,
especially for the energy-related
sectors in North America and the
Middle East and more recently
mining sites in South America
and Australia, customers are
starting to require models with
larger lifting capacities.
“This trend is primarily
stemming from the facilities at
jobsites becomes larger due to
continuous growth of scale for
both the energy sector and mining sites,” a
spokesperson from Tadano explains. “This
is the reason why our former largest class
rough terrain GR-800EX/1000XL is the
most popular capacity in Tadano. Among
the five types of our rough terrains, the
GR-800EX/1000XL has the top share by
35 % of sales.”
A spokesperson from Manitowoc
points out another reason for the increase,
“Larger-capacity models offer better tip
heights and multiple boom extension
configurations for improved versatility
and reach. Our new models, such as the
Grove RT9150E and Grove RT770E, have
best-in-class tip heights that have made
the cranes more useful, even where a small
tower crane or an all-terrain crane would
have been used in the past.”
These demands are being experienced
in India, with customers requiring higher
capacity rough terrain cranes with longer
boom length. To meet these needs, TIL,
a provider of equipment for the Indian
construction industry, provides five
different rough terrains with 20, 30, 40, 55
and 75 tonnes capacity. The models meet
India’s BSIII (CEV) emission standard,
which is in line with US Tier III and Euro
Stage 3.
“The latest ranges of rough terrain
cranes have a much longer boom length
compared to the earlier models,” Somnath
Bhattacharjee, president material handling
SRC865/SRC865XL models and the
85 ton (77 tonne) SRC885 rough terrain.
The SRC840 has a 31 m four section main
boom and a 7.9 m to 13.7 m extension. It
has a capacity of 40 US tons (36 tonnes)
at a radius of 3 m. It weighs 32 tonnes
and measures 12 m long, 3.4 m high
and 2.6 m wide.
The SRC865 has a 34.4 m four section
main boom and a 9 m to 16.3 m extension.
Capacity is 65 US ton (58.9 tonne) at a
radius of 3 m. Maximum height with
extension is 53 m. With manoeuvrability
one of the focuses of the design, the crane
weighs 40.7 tonnes and measures 13.7 m
long, 3.3 m wide and 3.7 m high.
Keeping reach in mind, the SRC865XL
has a 42.3 m five section main boom and
a 9.2 m to 16 m extension. The model is
fitted with a large cab and has a maximum
capacity of 65 US ton (58 tonnes) at 3 m
radius. The SRC865XL weighs 44.6 tonnes
and has a length of 13.9 m, a height of 3.7
m and a width of 3.3 m.
Kyle Nape, senior vice president Sany
Lifting Group, North America, Sany
America, says, “We are in development of
a larger rough terrain model for the North
American market. With all Sany global
cranes, we use US-built Cummins engines,
Dana transmissions, Braden winches and
Axletec axles as standard equipment.”
From Manitowoc is the 65 US ton
(58.9 tonne) capacity Grove RT770E
rough terrain crane and the 50 ton
(48.5 tonne) Grove RT550E. Speaking
on the design ideas behind the models,
Michael Herbert, director, product
planning and marketing Manitowoc
Cranes, North America, says, “The RT770E
offers a full-power, Megaform boom with
dual operating modes for structural and
stability load charts. The RT550E offers a
Twin-Lock Megaform boom, which is our
first introduction of this boom technology
to this size of rough terrain crane.”

ROUGH TERRAINS
A Link-Belt RTC-8080 Series II was used
at a ski lodge in the Green Mountains near
Killington, Vermont for a steel erection job.
The rough terrain accessed the jobsite after
climbing steep inclines and traversing water
bars during the lodge’s offseason summer
months. It could travel up an existing ski
trail and the 80 US ton (72 tonne) capacity
rough terrain was used for a 45 piece per
day steel erection schedule for a new lodge
at an elevation of 1,280 m.
