3-phase AC technology with high efficiency factor Energy reclamation during lowering and braking Ergonomic swivel seat Swivelling forks for load pick-up directly from the floor Lift height up to 13000 mm 80 V 3-phase AC technology Constant application of 3-phase AC technology for travel, hydraulics and steering drive is characteristic for the ETX 513–515. The advantages are obvious: Optimum energy consumption through particularly favourable efficiency factor. High efficiency factor of hydraulic system through rpm control of hydraulic motor. Optimised thermal economy allows the use of corrosion-free, heat-resistant plastic containers for hydraulic oil. Excellent efficiency factor for motors. Dynamic movement sequences. Reduced maintenance through omission of components susceptible to wear. Economic efficiency During lowering of the load or empty load pick-up device, energy is fed back into the battery = “regenerative lowering”. The energy is also fed back into the battery when braking the travel movement = “regenerative braking”. The energy reclaimed in this way is available for subsequent energy consumption. The advantages: Longer operating times with the same battery capacity. Shorter battery charging times with at the same time longer battery life. Lower investment costs for smaller batteries and lower energy costs.
