A.5.1. Maximum torques
All Schlumpf gears are calculated for a torque of 250 Nm.
Short physical excursion: if there is a weight of 100 kg acting on a pedal (equals a power of about 1'000 Newton) with a lever arm of 170 mm length, torque is 170 Newton meter (Nm). This is the torque of a midsize car! The only difference: the engine of this car has more power, because it combines this torque with a high number of revolution of the engine.
That's why all Schlumpf drives can be used on tandems as well as rikshaws and other heavy duty applications.
Please consider that the rear gearing component may allow a reduced torque only.
