New smart dozers provide faster working and greater efficiency - Mike Woof reports

Chinese dozer development 1171 Shantui continues to develop its dozer line, following on from the unveiling of the top-of-the-range SD90 model late last year. The 105tonne SD90 with its 708kW diesel features a 45m3 blade and is still in development, with a launch date still to be announced. However the company is now offering the latest version of its proven SD32 platform, the SD32PLUS bulldozer. This machine is part of the new PLUS range of improved bulldozer models Shantui is now offering, featuring upgraded operator controls, new 196 Cummins diesels, and more robust hydraulics. The company claims that its SD32PLUS is its most technologically advanced bulldozer so far. The SD32 models weigh in at just over 37tonnes and are powered by diesels rated at 235kW. Meanwhile the SD22E extended track bulldozer is a modification of the firm’s existing SD22. Performance and reliability have been increased while fuel consumption and maintenance needs have been reduced. The machine’s extended track length helps reduce ground pressure, although the machine is said to offer high manoeuvrability. The SD22E is designed for earthmoving operations on soft ground and is available with various engine options including units from 2731 Weichai Power, Weichai Deutz, Cummins and Shangchai. This 24.6tonne dozer is powered by a 162kW diesel.
