Descripción del Producto
Fabricada en Hefei con precisión de empresa conjunta, esta Hitachi ZX200-3G de 2014 ofrece rendimiento de 20 toneladas mediante hidráulica japonesa probada y un motor turboalimentado ISUZU AA-6BG1T. Con potencia nominal de 110 kW a 2100 rpm, el motor de 6 cilindros refrigerado por agua acciona bombas de pistones axiales variables duales que suministran 194 l/min cada una, generando presión de trabajo de 34.3 MPa para ciclos de excavación ágiles. La fuerza del cucharón alcanza 151 kN mientras que el brazo entrega 109 kN, respaldado por un cucharón retroexcavador de 0.91 m³ y geometría optimizada de pluma/brazo (pluma tipo H de 5.68 m, brazo de 2.91 m).
Especificaciones Técnicas Principales:
