The Sany STC500 has a rugged, fabricated
high tensile steel chassis held together by
a strong integrated welding structure which
forms a solid base on which to manage
the full capabilities of the 50 tonner. The
additional structure which gives the unit
its working foundation are the four-point
H-shaped outriggers, independently hy-
draulically controlled for both vertical and
horizontal extension. When fully extended,
the outriggers have a maximum span of
6 m x 7.2 m.
The heart of the drivetrain is a Dongfeng
Cummins ISLe 340.30 turbocharged, six
cylinder diesel engine. With its 6.9 litre
capacity, it has a power output of 250 kW
@ 2100 rpm and a torque of 1425 Nm
@1100 – 1400 rpm. Driving through a
9-speed synchronised transmission, power
is transmitted to the rear, twin driving ax-
les. All 12 wheels on the STC 500 have the
same 12.00R20 tyres size, an affordable
tyre to maintain or replace.
The working end of the Sany STC500 is
the superstructure, comprising boom and
operators cab. The boom itself has a maxi-
mum length of 42.5 m, comprising five high
tensile steel sections which have optimised
strength by virtue of their U-shaped design.
The design has significant weight reduction
with a compensating increase in strength. In
addition, the STC500 is fitted with a standard
16 m fold away fly jib with off sets of 0,15
and 30 degrees. This combination gives the
unit a total lift height of 58.8 m. Standard
equipment on the STC500 is a 2
nd
auxiliary
winch and the Sany Safe Load Limiter (SYML)
with an external robotic light indicator. The
3.5 ton rear mounted counterweight is fixed
therefore eliminating the need for additional
transport for the counterweight.
Morne Jute with his years of experience of
cranes in the local market, is upbeat about
the future of Sany in South Africa and in
concluding said, “Buyers of any form of mo-
bile crane, be it All-terrain, Truck mounted
or Rough Terrain, should always be aware
of the application and be sure of the class
of crane they require before purchasing. A
Sany truck mounted or a rough terrain crane
may be a suitable option in your fleet”.
