This results in horsepower greater than ratedpower. The combination of increased torque rise and maximum horsepowerimproves response, provides greater rimpull, more lift force and faster cycletimes. Maximum flywheel power of 128 kW (172 hp) occurs at 1,700 rpm whenpower is needed during the working cycle.IT38G Integrated Toolcarrier specifications15
