The Ergopower L II hydrodynamic powershift transmission from ZF Passau transmits engine power up to 400 kW (540 hp) and offers maximum input torque of 2500 N·m (1845 lb·ft) without interrupting tractive force. Designed for dump trucks of up to 50 t (55 ton) payload, the transmission features eight forward and four reverse gears to increase the transmission ratio and improve high-load carrying on off-road surfaces, while a wide overall transmission ratio reduces engine speed. Equal ratio steps allow increased driving speeds at low engine rpm, with reverse operation of 20 km/h (12 mi/h). An integrated primary retarder improves brake performance and can replace the service brake at low speeds, preventing wear; directly mounting an axle drive to the transmission housing creates a compact design.
