Un open-air DTH drill rig es nuevo equipment upgraded in response to the country environmental protection requirements. Equipado con el motor four-cylinder National III de Yuchai a meet the country requirements for emissions y environmprotectionental. Adoptando zambullidar caminando motor, engineering four-wheel area, increase working pressure e increase climbing pe7511367556750. Incr alivie el tono y boom cylinders a meet el requirements of extreme posiciones.
En el same time, el sistema hidráulico hidráulicom está actualizado para incr facilitar el sistemam f bajo e incr reducir la velocidad de rotación r. Optimize el lifting cylinder a improve reliability. Tla guía rail adopta una instalación inclinada, que es conveniente for operation y observation. The cover adopta thicker profiles y agrega izado r, lo cual es conveniente for para cargar, descargar y izar.
T el tipo KG320H agrega un colector de polvor y adopta el cilindro de captura de polvo – doblers, que are more environm mentalmente fr amigable y r confiable cuando se trabaja con wor.
