Chinese manufacturer Sany launched a 110 ton capacity telescopic boom crawler crane, the SCC8100TB, at the ConExpo show in Las Vegas, USA, 4 to 8 March. It has a 156-ft. five section, full power boom with a pair of single stage double acting extension cylinders. To save weight and increase capacity, a synthetic fibre rope is used instead of a wire one inside the boom on the extension and retraction system. A heavy duty version of the crane with a four section boom will also be offered. A swing away jib is standard and jibs are available from 35 to 59 ft. long.
It has the company’s distinctive UltraCab operator cabin. Power is from a 224 kW Cummins QSL9-C300 Tier 4 Interim (Tier 4 Final by the end of 2014) diesel engine driving Rexroth hydraulics. Line pull with the 24 mm hoist rope is 15.7 tons. The width of the crawler undercarriage can be altered by hydraulically moving the track frames.
The basic machine, in Series 1 configuration, weighs 50 tons, is 53 ft. long, 11 ft. wide and 10.5 ft tall without crawlers. The crawler track frames are 26 ft. long, 3 ft. wide and 4.1 ft. tall. Each weighs 12.7 tons. As Series 1 it can travel on three trucks. An extra truck is used for the Series 2 configuration with an extra 22 tons of counterweight.
