COVER STORY

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.

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”. b
