I often see the difference between Hitachi 200-2 and 200-3 in the forum. Today, the editor of China Machinery will give you the knowledge of Hitachi EX200. First of all, we have to figure out one thing. Hitachi 200 excavators have two types: EX200 series and ZAXIS200 series (often referred to as ZX200).
EX is Hitachi’s earlier name for excavators. ZX series is an upgrade of EX, full name ZAXIS. ZX is developed by Hitachi on the basis of improving the reliability of the original EX hydraulic control system.
It is a relatively novel machine recently. Based on the EX, the electronic control equipment is simplified, the pump displacement angle sensor is directly discarded, and the main control valve is simplified.
Added an integrated shuttle valve, electronic diagnosis and storage system. In the component design, the arms and walking brackets are also strengthened.
