Larsen & toubro limited has incorporated a new hydraulic excavator, model l&t 180 ck, in the 35-tonne class. This is produced by l&t komatsu at their iso 9001 accredited plant, and surpasses the earlier model 170 ck. The new model has greater engine power and productivity, higher operating speed and is more fuel-efficient. It is powered by a cummins 4-cycle liquid cooled, direct injection, 6-cylinder turbocharged diesel engine, which provides 286 hp @ 2000 rpm. The maximum torque is 1,149 nm @ 1,500 rpm. The varidyn hydraulic system offers optimum conversion of engine power into hydraulic power. All hydraulic cylinders of the machine are cushioned to minimise shocks. The operator cabin is spacious with an ergonomically designed seat.
