Heavy-duty electric counterbalanced forklifts, with a load capacity of 6-18 tons and a lifting height of 3-8 meters, do not simply replace diesel engines with electric motors, but thoroughly optimize the hydraulic system. Independently developed variable speed load-sensitive dedicated control system, large closed-loop feedback of hydraulic parameters, torque prediction and direct torque control, global power matching, on-demand oil supply, and reduced throttling and overflow losses. Imported electronic control is used, and the vehicle is equipped with lithium batteries as standard, with a stable system, strong power, and greater safety and efficiency.Non-standard customized solutions can be provided according to customer requirements.
