The effective tire diameter of the front tires is significantly reduced when lifting heavy loads
- The effective tire diameter at the front can be significantly reduced with heavy loads
- The torque requirement when driving empty is around 50% / 50% front/rear. But over 90% front when picking up a load
- For this reason, the front and rear axles are often coupled in terms of drive technology and operate at the same speed
- As a consequence, there is considerably too much slip on the lighter rear-wheel drive with heavy tire wear

Our approach: separate front and rear drives with simultaneous estimation of the effective tire diameter without additional sensors

Realization of the lifting movement by direct control of the hydraulic pump using VECTOPOWER inverters. Estimation of the lifting force and thus the tire flattening using our VirtualSensor technology.
