The 2.5–3.5t high-voltage lithium battery rough terrain forklifts are an independently developed new series that merge the strengths of the XH series heavy-duty high-voltage lithium forklifts and rough terrain internal combustion forklifts. Breaking away from traditional designs, this next-generation rough terrain forklift features an innovative dual-motor high-voltage drive system and a high-voltage platform inspired by new energy vehicles. This combination delivers both the rugged performance of a rough terrain forklift and the smooth comfort of an electric forklift.
