With this electromechanical steering system (image 5), ZF presents the future of steering axles for four-wheel front-drive counterbalance forklifts. ZF is thus advancing the electric forklift, enabling it to follow following the course plotted by the passenger car industry over the last few years: the move from hydraulic steering to energy-efficient electrical steering systems. Steering based purely on electromechanical power is finding its way into ever larger vehicles and higher performance classes, as is the case with automotive applications.
ZF's eSTEER EPS 4 is a type of electromechanical steering for four- wheel front-drive counterbalance forklifts. Thanks to perfectly designed gearing parts, noise pollution is extremely low. Premium, high-quality and long- lasting components obviate the need for maintenance across the product's life cycle.
ZF eSTEER EPS 4 is also very economical throughout the driving cycle, thanks to the power-on-demand feature, which guarantees longer battery life and reduced energy consumption. The newly developed steer-by-wire system functions entirely without hydraulics, meaning that leaks and associated environmental hazards are prevented.
