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.
EX series EX200-2/3 are all imported. From the perspective of pump and engine connection, EX200-3 has an independent transmission mechanism, and the position of pump control solenoid valve (high speed) in the pump is different from EX200-2; -3 increases The forearm recovery pressure sensor. PVC and EC controllers can be used in common.

The ZX series has ZX200 and ZX200-3, but does not have the ZX200-2 model. Hitachi ZAXIS 200-3 uses a new generation of engine · OHCR valve engine 122 kW (166 PS) / 2,000 min-1 (rpm) compared with ZAXIS200, the power is 11% higher than that of ZAXIS 200, increased high pressure common rail electronic control fuel injection system, cold EGR *System LL.If there are deficiencies and errors, please correct me.
