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. Adopte zambullidar caminando motor, hemmed crawler frame, y engineering four- correa de rueda para increase working e incrustación de. 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. The gyrator adopta un large motor reducer a incrfase el turning arque y velocidad. To incr suelte el lifting cylinder y la cadena, improve el lifting force y reliability. Reinforce la guía rail e incr suelte las placas upper y lower wear of la placa deslizante para extender el service life. Tla guía rail adopta una instalación inclinada, que es conveniente for operation y observation. The cover es f doblado con thicker profiles para increnganche strength y rigidity, y la elevación r se agrega para facilitar la carga, descarga y elevación.
The KG520H tipo agrega un colector de polvor a incrair volume e improve la succión de polvo effect. Adopta el cilindro de captura de polvo – doblers, que are more environmentally friendly y reliable cuando working.
