• The wheeled excavators WE190 – WE210 – WE210 Industrial – WE230 – WE230 Industrial are operation hydraulic machines.
• They essentially consist in a wheeled undercarriage on which a slewing bearing is mounted, which is coupled to the upper frame.
• The upper frame supports the front attachment, the engine, the hydraulic components, the cab, the fuel tank and the counterweight.
• When the operator activates the controls (hydraulic control levers and pedals), the hydraulic pumps rotated by the engine suck oil from the tank and convey it to the control valve; the control valve, in turn, sends it to the relevant users.
• A cooling system keeps the hydraulic fluid at a normal operating temperature.
